These are now available from ACASIAN for licensing worldwide for commercial and government purposes and academic uses (licences for academic research are with minor exceptions supplied at a 50% discount).
The standard scale/resolution is 1:1M (apart from the Low Resolution Data designed for printable output, which has also been rescaled to match the 1:1m datasets).
The Land-Use Map of China (LUMC) coastlines and international boundaries are standard, although data can be supplied fitted to the Digital Chart of the World (DCW) coastline or other base maps at extra cost of A$750.
Although data are ordinarily shipped in decimal degrees using WGS84 (latitude/longitude, or what ESRI calls a 'geographic' projection), a custom Albers Equal Area projection is available for all China data at no additional charge.
All data are vailable in ARC/INFO Workstation coverages or export format (.e00), ArcView shapefiles, and MapInfo Formats. However, Chinese characters become illegible when coverages are converted into shapefiles.
PRC ADMINISTRATIVE SYSTEM DATA (1:1M High Resolution)
- PR China Administrative Unit Dataset (includes regions for ADM1, ADM2, ADM3, and ADM3.1 - Urban Distrits)
[PRC-ADM]
-
The ACASIAN administrative datasets for China are up-dated on a yearly basis whenever a new edition of the 'Administrative Handbook of the PRC' (Zhongguo Renmin Gongheguo Xingjengqu Huajiance) becomes available. A major up-date is made whenever a new edition of GB/T 2260 'Codes for the administrative divisions of the People's Republic of China' is published. The latest edition presently available to ACASIAN, GB/T 2260 - 2002, published on 2002-05-08 contains Administrative Guobiao Codes current to 2002-10-01, and is the basis for the current major up-date expected to be completed during 2007.
The up-dated China Administrative Dataset will include at least approximate urban district (shixiaqu) boundaries (polygons) in all 275 ADM2 'higher-level municipalities' (dijishi and zhixiashi). There are in total approximately 2,800 regionalised administrative units, including the urban districts (shixiaqu), made from around 4,000 polygons incuding those for off shore islands and various enclaves, digitised from 1:1m or larger scale sources. ADM1, ADM2, and ADM3 regionalised coverages are also included in the administrative datasets, and the Hong Kong and Macao Special Administrative Regions are now incorporated at all levels.
All units are identified with their 2002 Guobiao codes and names in Chinese characters (GB or UTF8 encoded) and pinyin and luomaji romanisation systems.
For equivalent units, population figures from the 1990 census and for the end of 1995 from Provincial Statistical Yearbooks (except for Hubei, for which 1994 figures are available at present). End of year population figures from the household registration system are also available for 1996 and 1999, and 2000 census figures for total population numbers are now included.
A wide range of demographic, economic and agricultural variables may be available for some years, postal codes (see below) are available, and boundary data matching any other date back to 1980 can be produced as required.
The end of year 2000 administrative system of the PRC, as documented in the 2001 edition of the 'Administrative Handbook of the PRC (Zhongguo Renmin Gongheguo Xingjengqu Huajiance) is still the most current version available pending the completion of the update to end of 2000. Versions matching earlier editions of Guobiao Administrative Codebooks (1995 and 1991, current to 01/02/1996 and 01/01/1992, respectively) are standard items.
These administrative data normally use Land-use Map of China coastlines, but can be supplied fitted to the DCW for an extra A$750.
A single- user licence for the up-dated 2002 administrative dataset is A$3,300.
Generic post codes (four significant digits plus two zeros) can be included for an additional charge of A$1,350 when ordered at the same time as the 2000 or 2002 administrative datasets.
Upgrades to the 2002 dataset for those who have previouisly obtained licences for ACASIAN PR China administrative datasets will be A$750. Administrative datasets for the standard earlier dates discussed above are A$750 when ordered with the 2000 or 2002 datasets, or A$3,300 separately. Any other years back into the 1980s, A$4,000 each.
Prices for additional attribute data available on request.
Individual provinces are available separately for A$250 to $750 depending on their complexity, including several variant versions for the Tibet Autonomous Region and Qinghai Province from various and varying sources.
- Administrative Unit Regions matching the PR China 2000 Census
[PRC-Census]
- These data are current as of the census date of 01/11/2000 down to county-level (ADM3), including Counties (xian)
and County-level Municipalities (xianjishi). ADM3_1 Urban Districts (shixiaqu) should be completed for all 'higher-level municipalities' (dijishi and zhixiashi) by mid 2007.
Including the urban districts, there are approximately 2,800 regions made from around 4,000 polygons including offshore islands and various enclaves, digitised from 1:1m or larger scale sources.
These data are also available as of the end of 2002 as documented in the 2001 edition of the 'Administrative Handbook of the PRC (Zhongguo Renmin Gongheguo Xingjengqu Huajiance).
All administrative units are identified by official census codes from Xianji Ji Yishangqu Haomingcheng Daimayu
plus Chinese characters (GB encoded) and pinyin names.
All 2000 data, regionalised at ADM1, ADM2, ADM3, and ADM3.1, A$3,300
- PR China High-Resolution Administrative Dataset for CDC 2000 Census Data
[CDC-CENSUS]
-
The China Data Center at the University of Michigan distributes a CD-ROM containing a large number of PR China 2000 census variables at the 'county-level'. The CD contains quite low-resolution spatial data in an obscure projection to allow the census variables to be displayed in ArcView. The ACASIAN high-resolution spatial data for the PRC administrative system has now been coded and regionalised to match the administrative codes employed on the CDC CD_ROM so that their census data can be incorporated into an ACASIAN high-resolution spatial data in a variety of GIS environments. By agreement with the China Data Center, ACASIAN can supply their census data joined to this dataset if supplied with proof of purchase of the CDC CD-ROM. The single-user licence price of this dataset is the same as for other contemporary ACASIAN PRC administrative datasets, A$3,300, unless the census data are joined, in which case there will be an additional A$700 processing fee.
- Administrative Unit Regions (ADM3) Matching the 1990 and the 1982 PRC Census Dates [PRC-A3C]
- Two coverages, as of 01/07/1990 and 01/07/1982, with county-level boundaries precisely matching published census data.
Total populations for each county-level unit are included, along with Guobiao codes (both the official ones and the alternatives occasionally used by the State Statistical Bureau for census returns) and names in both Chinese characters and pinyin.
1990 boundaries, A$3,300; 1982 boundaries, A$2,500; both dates, A$5,000; combined with other standard dates, above, A$1,000 each or both A$1,500 in addition. Individual Provinces for each census, A$250 - A$750.
PRC ADMINISTRATIVE CAPITAL POINT DATA (Cities, Counties, and Urban Distrits)
- Major 2002 Update - Cities, County Seats, and Urban District Centers for the PRC [PRC-C3]
- Points for year 2002 administrative capitals for counties (xian) and county-level municipalities (xianjishi), including urban district centres shixiaqu chengguan in higher-level municipalities (dijishi), including Hongkong. All points are identified with Chinese character and both pinyin and luomaji romanised names, and are coded with the Guobiao codes of their administative units as of the GB/T 2260 - 2002, which has a currency date of 2002-10-01. Year 2000 census total population figures are supplied and other variables can be supplied under certain circumstances.
A single-user licence is priced at A$1,350, or A$700 when ordered with the high-resolution 2002 Administrative System dataset, above, for a total of A$4,000. Up-grades for those who have obtained a licence for an earlier date, A$350. Generic post codes (four significant digits plus two zeros) can be included with this dataset for an additional charge of A$1,350 (unless that charge was paid for a postcode regionalisation of administrative unit data ordered at the same time).
- Cities, County Seats, and Urban District Centers for Earlier Dates
- Capitals matching any of the 2000, 1999, 1998, 1996, 1992, 1990 and 1982 boundaries, A$1,350 each ($700 additional when ordered with a matching high resolution administrative boundary dataset); all seven dates, A$4,000. Individual provinces for any of those dates, A$150 - A$350. Half price when ordered with a matching set of high resolution boundaries, above.
PRC TOWNSHIP SEAT POINTS (Including points for all Cities, Urban District Centres, County Seats, and Townships: Jiedao, Zhen and Xiang)
- PR China 2000 Census Township Points Dataset
-
The 2000 PRC census data available from the China Data Center, University of Michigan, includes figures for around 51,000 township-level units (jiedao, zhen, xiang, and their variants) plus all higher-level administrative centers. Points representing all of the township seats (xiang and zhen) as well as some accurate urban 'street committee' (jiedao) office locations and approximations for others have now been geo-referenced by ACASIAN, which allows the entire population of the PRC (apart from the Hong Kong and Macao Special Administrative Regions) to be analysed at the ADM4 township level. Most of the 6,000 or so urban street (jiedao) points cannot be located accurately, so they have been arbitrarily grouped within their urban district boundaries and the built up area polygons for their cities, which are included with the township point dataset. In some cases, the 'street' points can be located more accurately within the urban districts and the builtup area polygons in terms of their postcodes. The several hundred township seats that could not be found on any maps have been handled in a similar matter, being located close to their administrative unit captial.
Clients who first obtain the township census data from the CDC may obtain the township points from ACASIAN with those data joined, but depending on the amount of data involved there may be significant additional processing costs. Postcodes will be available for most of these points, apart from some of the 'streets' as described below.
A single-user licence for the full set of 50,000 township level points is priced at A$10,000. Provinces are available separately, at A$350 - A$1,350 depending on their complexity. Contact l.crissman@griffith.edu.au for more information.
- Voroni Polygons for Township Seats (Xiang and Zhen) in the PRC 2000 Census
[TNSP-TP]
-
Thiessen Polygons are constructed in a field of points by dividing the distance between them with lines that inevitably form polygons. When constructed within a set of existing larger polygons, they are called Voroni polygons. These have been constructed within city, urban district, and county boundaries and outside urban builtup area polygons for all township seat (xiang/zhen) points, but not for 'streets' (jiedao). The results simulate rural township boundaries, and allow the CDC township level census data to be displayed in choropleth maps. When incorporated into the 2000 census administrative dataset, the resulting Voroni polygons bring the total combined price to A$15,000, including the township point dataset, above.
- Cities (shi) and All 1990 Officially Designated Towns (zhen) in the PRC [PRC-CT)
- All cities (shi), county seats (xian chengguan), and larger rural towns (zhen) as of the 1990 census (approx. 12,500 in total, including around 10,000 of the largest rural 'towns' in China in addition to the capital city and county seat points).
All points are identified with Chinese character and pinyin (romanised) names and with Guobiao-based codes derived from GB/T 2260 - 1991, current to 1991-05-05.
Supplied with 1990 census figures for Urban-Registered Population, only.
Six-digit postal codes are available for all of these points - see below.
Cities and official towns as of 1990, $3,300. All cities and official towns for individual provinces for any date, A$250 - A$750.
PRC POST CODES
ACASIAN postcode data were produced from the Atlas of Chinese Postal Codes under copyright permission obtained from the publisher,
the Haerbin Cartographic Publishing House.
(Due to copyright restrictions, postal code data derived from the 'Atlas of Chinese Postal Codes' cannot be licenced to clients in PR China, including the Hongkong and Macao Special Administrative Regions.)
Yearly editions of the PR China Administrative Division Handbook
(Xingzhengqu Huajiance) are used for supplemental postcode information, as are other sources as they become available, such as 'The Postal Code Atals of China', Chinese Post Office, 2005.
NOTES ON THE PR CHINA POSTCODE SYSTEM AND ITS RELATIONSHIP TO THE OFFICIAL CIVIL ADMINISTRATIVE SYSTEM
The subject of PR China postcodes is not entirely straightforward. When they were established, the system followed the official civil administrative system of the country only partially, departing from it at both the higher levels and at the level of the then urban districts constituting the ADM3 municipalities (shixiaqu) belonging to ADM2 municipalities (dijishi) as well as the ADM2 municipalities (also shixiaqu) within the ADM1 municipalities (zhixiashi). In this convention for designating
administrative levels of a country, ADM0 is the whole country, ADM1 are the first order divisions, ADM2 are the secondary divisions of ADM1 units, and so
forth. ACASIAN uses ADM3.1 to designate PR China urban districts (qu), which are the subsidiary components of
the ADM3 municipalities (shixiaqu) contained in ADM2 (dijishi) or
ADM1 (zhixiashi) municipalities, so regionalisation at this ADM3.1 level
displays and allows analysis of urban districts (qu) in conjunction with
counties (xian) and county-level municipalities (xianjishi). PR China’s ADM4 divisions are the rural
townships (xiang and zhen) and the urban streets (jiedao).
Essentially the postcode system divides
the larger provinces into two or more postcode divisions having two significant
digits, but the three original ADM1 municipalities (zhixiashi – Beijing,
Tianjin, and Shanghai) and other provinces with relatively small populations
comprise only one such division.
However, in some cases, these highest postcode divisions extend over
parts of multiple provinces. In
particular, the western portions of Neimenggu are joined with divisions that
are predominantly for Ningxia and part of Gansu, and smaller portions of it are
joined to divisions belonging primarily to Jilin and Heilongjiang. A small, non-contiguous portion of western
Hebei belongs to the same division as Beijing, and there are other
non-contiguous parts of divisions in Shanxi and Shaanxi. When Chongqing was separated from Sichuan
in 1997 as a forth ADM1 municipality, the existing postcode divisions were
retained, so one spans parts of both provincial level units.
Because their number is always smaller
than the ADM2 divisions in a province (diqu or dijishi) or in an
ADM1 municipality (shixiaqu or shixiaxian), the two digit postcode
divisions contain multiple ADM2 units.
Provincial capitals and the combined inner urban districts of ADM1
municipalities (perhaps all of the ADM2 municipality, or shixiaqu, that
existed at the time the system was established) have the first two divisional
digits followed by four zeros, the first one or two of which are actually
specific to the particular complex ADM3 municipality (shixiaqu) more or
less representative of the original area of the capital city per se (in
contrast to its eponymous municipality).
However, the third digit for a division may not be specifically applied
to the whole ADM2 administrative area, as it can also extend to neighboring
ADM2 units, or parts thereof.
The closest correspondence of postcodes to
administrative units is at the ADM3 level consisting of counties (xian)
and simple county-level municipalities (xianxiashi). The administrative centers of ADM3 units,
whether county seats (zhen) or cities in the case of ADM3 municipalities
(xianjishi), have postcodes with four significant digits (which can
include zeros as described in the previous paragraph) followed by two
zeros. When applied to their whole ADM3
administrative units, these become ‘generic’ postcodes, as all places within
them have specific postcodes with six significant digits but the same first
four digits. However, multiple
neighboring ADM4 rural townships (xiang and zhen) often share the
same ‘specific’ six digit postcode, and some are assigned uniquely to places
(or sets of places) that are not (or do not include) ADM4 administrative seats,
so the correspondence of postcodes to administrative divisions breaks down at
the ADM4 township level.
The above correspondence between generic
postcodes and administrative units at the ADM3 level does not apply to the sets
of old inner urban districts (shixiaqu, or parts thereof) of larger cities (now
capitals of ADM2 dijishi or ADM1 zhixiashi), which are divided
into significantly more numerous and hence much smaller urban postcode zones, which normally do not
share boundaries with the sets of urban districts (qu, or parts thereof)
which they are distributed across.
However, the specific zone postcodes all have the same generic first
three digits belonging to the capital city of the municipality. The urban equivalents of the rural
townships, 'streets' or street committees (jiedao), take the specific postcodes of the urban
postcode zones in which their administrative offices are located, so different
'streets' can share the same specific six digit postcode.
In the most recent 1997 edition of the
Atlas of Chinese Postal Codes, for certain larger cities even more specific
postcodes are shown for particular urban institutions, such as universities,
government bureaux, or factories (or collections of factories). They may or may not correspond to the first
four or five digits of the urban postcode zones in which they are located, and
some of them have the same final two digits, 49 being typical.
Chinese postcodes are rarely
changed (although some were in 2002), although they can be added to (as with the institutional codes just
described, above) or when new urban postcode zones are added where there were none
before in developing parts of a city, but the field administration units do
change in one way or another at a rate of perhaps 1-2% per year, on
average. Recently, two kinds of changes
have occurred most frequently. The
first involves the promotion of ADM2 prefectures (diqu) to equivalent
ADM2 municipalities (dijishi), which can involve the promotion of remote
prefectural capitals to cities, and/or the creation of at least one urban
district (qu) at ADM3-1 level to populate a new ADM3 ‘complex’
municipality (shixiaqu) which all ADM2 municipalities must apparently
now contain. The second kind of change
is to incorporate counties (xian) or simple ADM3 municipalities (xianjishi)
as additional urban districts in the ADM3 (shixiaqu) units of their ADM2
municipalities by promoting them to urban districts (qu), again with
some possible name changes. This also occurs frequently in the four ADM1 municipalities
(zhixiashi). In some more highly
developed parts of China, the spatial distinction between the ADM2 (dijishi)
municipality and its ADM3 complex municipality (shixiaqu) is nearly gone as the
latter now incorporates all or most of the previous counties and county-level
cities in the ADM2 municipality.
Fortunately, there seem to be no consequences for postcodes in any of
these administrative promotions, as the same old generic codes (four distinct
digits plus two zeros) still apply to the promoted units.
However, when the enlarged ADM3
municipalities (shixiaqu) are regionalised on the basis of the levels of
administrative units, those old generic postcodes get absorbed into the higher
order generic postcodes (three distinct digits plus three zeros) belonging to
their ADM2 (or ADM1) municipality, and will therefore be invisible when ADM3
level administrative units are displayed or analysed. However, when the administrative data are regionalised at the
ADM3-1 level to display or analyse all of the separate urban districts
belonging to the ADM3 municipality (shixiaqu) component of ADM2
municipalities, only the urban districts which were once separate ADM3 units in
their own right will have their own generic postcodes because the older inner
urban districts are divided into some larger number of the urban postcode zones
that do not align with the urban district boundaries.
The solution to this situation, with
respect to GIS spatial data for PR China postcodes, is to regionalise the
administrative data using the generic postcodes (three or four distinct digits
plus zeros), not the official administrative codes. If this is done, then those promoted urban districts that have
their own established generic postcodes (four significant digits) will be
retained as separate regions, whereas the older inner urban districts that
contain smaller urban postcode zones and therefore do not have their own
generic postocodes will be amalgamated under the higher order generic postcodes
(three significant digits) belonging to their ADM2 municipality.
PRC POSTCODE POLYGON/REGION DATABASES
- Generic Postcodes for Counties, Municipalities, and Some Urban Districts
[PRC-PC3A]
- The postcodes in these datasets match the
latest 1997 Atlas of Chinese Postal Codes (Haerbin Cartographic Publishing
House) or newer information from the yearly editions of the PR China
Administrative Division Handbooks and the Internet. As
discussed above, generic postcodes pertain to administrative units at the ADM2 (three significant digits plus three zeros)
and ADM3 levels (four significant digits plus two zeros). The latter also pertain to many ADM3-1 urban districts
which have been promoted from counties or even municipalities over the past decade or more.
These generic postcode datasets have been regionalised using the lowest level of
generic postcodes, not the official administrative code system. They are available as additions to datasets
for the county-level administrative units (regions)
and for any of the dates mentioned above under
PRC ADMINISTRATIVE SYSTEM DATA.
Generic postcode regionalisations
are priced at A$3,300
when obtained alone,
or are provided for an additional charge of A$1,000 when
ordered together with an administrative system dataset (combined price, A$4,300).
- Internal Postal Code Zones for Beijing, Tianjin, Shanghai, Chongqing, Guangzhou, Dalian, and Thirty Other Large Cities
[PRC-SPCZ]
- The larger cities in China, or more precisely the core areas of the larger muncipalities, are divided into a number of urban postcode zones.
Polygon data for these urban postcode zones are identifiable only by their specific postcodes. They have no names, no attributes (such as populations or socio-economic data) are available for them, and in general they do not align with administrative boundaries for urban districts (qu) or urban street committees (jiedao).
Polygon vector data for the internal urban postcode zones are based on maps in the Atlas of Chinese Postal Codes, second edition, 1997.
These polygon datasets, plus matching raster images (.jpg or .img files)scanned from the ACPC, will eventually be available for
the 100 or so largest cities in china. Contact Lawrence Crissman for a current list of available cities.
Although ArcView 3.x shapefiles and MapInfo tab files for the postcode zones can be supplied, they will only match the Atlas of Chinese Postal Codes maps when both are registered in the appropriate UTM zone projections. However, .jpg images of the maps have been registered and rubbersheeted to match vector coverages in other projections, including decimal degrees, for use in ArcGIS (ArcMap or ArcView) 8 and 9. The registered map images are useful in relating the postcode zones to features such as city streets, etc.
Beijing, Tianjin, and Shanghai urban postcode zone data and registered map scans are A$750 each, Guangzhou and similar sized cities are1 A$425 each, and the cost for smaller cities is proportional to their number of postcode zones down to A$150 for places like Dalian. The registered raster images showing main streets, etc., in relation to the postcode zones for use with ArcView or MapInfo in UTM are A$500 and A$300, respectively, down to A$100 for the smaller places like Dalian. However, the map scans registered and rubber sheeted for use with ArcGIS or ArcMap (ArcView 8 or 9) are included with the urban postcode zone polygon data at no extra charge.
Contact l.crissman@griffith.edu.au for a current listing of cities for which urban postcode zone data and registered images are available, and their prices.
PR CHINA POSTCODE POINT DATASETS
ACASIAN has datasets for various collections of points coded with their postcodes, including all current cities, county seats, and urban district centers (approximately 2,800 points), plus all 10,000 or so larger towns (zhen) included in the 1990 census volumes. Work is underway to add post codes to the additional 35,000 or so township seat points (xiang and zhen) for the township 2000 census data available from the China Data Center, University of Michigan. (See 'PR China 2000 Census Township Points', above).
- Generic Postcodes for Administrative Capitals (Cities, County Seats, and Some Urban District Offices) [PRC-PC3C]
-
The generic postcodes belonging to cities, county seats, and urban district offices (plus the urban district offices with specific postcodes) can also be represented by point data for the administrtive centres. When they are ordered at the same time as a generic postcode regionalisation of administrative unit data for any date, there is an additional price of only A$650 for the administrative capitals with their generic postcodes. Ordered separately, postcodes can be included with the PRC Administrative Capital Point Dataset, above for A$1,350.
- Postal Codes for Official Towns (Zhen) Included in the 1990 Census Returns [PRC-PCSZ]
-
The 1990 PR China census returns inclued approximately 12,000 'urban' towns that had some number of 'urban registered population', people whose household registration status allowed them to live in officially designated urban places or who had 'urban' occupations (higher government jobs, professions, etc.) Although they vary widely in size in different parts of China, these official 'urban' towns (zhen) are the largest rural towns in their localities, and some have populations exceeding 50,000 or even 100,000. County seats are almost always such towns (except in Tibet and a few other remote places), in which case they have the same generic postcodes as their respective counties, and are included in the Generic Postcodes for Administrative Capitals dataset immediately above. The other 10,000 'urban' towns (zhen) have 'specific' postcodes (six significant digits), which are often shared with neighboring 'rural' towns (xiang).
Postcodes for the additional 10,000 official towns enumerated in the 1990 censusare A$2,650 in addition to the A$1,350 for the city and county seat points, which are only A$750 when orded with the Administrative System Dataset. So, the combined price for the 12,500 points with postcodes is A$3,400 when ordered with the administrative unit postcode regionalisations, or A$4,000 when orderd without the administrative unit postcode regions.
Post codes for the cities and towns of individual provinces, A$150 - $500 additional.
- Postal Codes for All PRC Townships (xiang and zhen) Included in the 2000 Census Returns [PRC-PCSXZ]
- The PR China 2000 census returns include data for approximately 45,000 rural townships (xiang and zhen including the 12,000 'urban' townships (zhen) in the 1990 census. In 2000, 21,000 of the townships had the official status of zhen, and there were another 6,000 or so ADM4 urban 'street committee' units (jiedao). Although most of the latter are impossible to locate on maps readily available to foreigners, ACASIAN has geo-referenced the location of the towns that serve as the administrative seats of the additional 35,000 2000 census townships. Postcodes are being added to those points, and that work may be completed by the end of 2007.
The single user price for the township seat points with their specific postcodes will be A$15,000. At present, the specific six-digit post codes have been added to the township seat points only for provinces in southwest China, Chongqing, Sichuan, Guiyang, and Yunnan, plus Liaoning. If this dataset is ordered now, free updates will be provided when available until all provinces are supplied
- Point Locations for PR China Urban Postcode Zones and Institutional Postcodes
[PRC-UZC]
-
As discussed above, inner cores of the larger cities in China are divided into a number of urban postcode zones that do not correspond with any of the internal administrative units of their muncipalities. In some situations, it is useful to represent these urban postcode zones with approximate centroid points that can be used with other postcode point data. In addition, in the latest 1977 edition of the Atlas of Chinese Postal Codes, some cities have additional specific postcodes for individual institutions such as universities, hospitals, and government bureaux. There can also be special postcodes typically ending in '49' that are applied to groups of factories, etc.
Centroid points are being created for all urban postcode zones along with points for the institutional postcodes, estimated to total approximately 1,500-2,000. This dataset, to be available soon, will be licenced for single-users at A$2,700.
- All PRC Postcode Points Dataset [PRC- APC]
- In addition to the postal Codes for administrative capitals and township seats, and the center points for urban postcode zones and institutions, there are other rural places in the Atlas of Chinese Postal Codes that have specific postcodes but are not official towns (xiang and zhen).
Those additional points will eventually be added to this dattaset, which will then include point locations for all PR China postcodes.
The single-user licence for all PR China points with postcodes, including urban postcode zone points and institutional postcode points, will be A$20,000 If ordered now, free up-dates will be provided to licencees until all of the postcode point dataets are complete.
CHINA TRANSPORT ROUTES
- China Expressways Dataset
-
A major update of the China Road Transport data has created a new dataset containing all four-lane (or more) divided expressways in PR China. All of the National Main Routes in PR China are included and identified, and when possible the names of expressways are included in pinyin and hanzi. For each province, eight sources of information were used to code each expressway section in terms of whether it was shown as completed, under construction, or proposed. As the sources rarely agreed completely, a judgement was made about the status of each expressway segment as of late 2003, the latest date of any of the sources employed. Nodes along the arcs have been created for all indicated interchanges, service centers, and toll gates, and where possible they are identified with pinyin and hanzi names. The expressways that were included in the China Road Transport dataset have been removed. A single-user licence for the new China Expressways dataset is A$2,500. An up-date based on 2005 sources has now been completed, and will be supplied to anyone licencing PR China expressway data.
- Road Transport Routes of China [PRC-RDS]
- Apart from the expressways contained in the new dataset, above, all routes connecting cities and most of the nearly 12,000 officially designated towns as of the 1990 census are included, distinguished in terms of national and provincial highways, and local roads, paved and unpaved. Route numbers are included for National Highways, only. National and Provincial Highways have now been updated using 2005 sources. Individual provinces available separately.
All data, A$6,500; Individual provinces, A$350 - A$1,350. National Highways, only, A$2,000, National and Provincial Highways, A$4,000.
- Railroad Routes of China [PRC-RLS]
- Complete railroad system of China according to circa 1997-98 sources were originally digitised, but these data have now been updated using new mid-2000s sources. Single and double tracks are distinguished along with narrow gauge, and electrified lines are indentified. Railroad jurisdictions are also attributed. Individual provinces available separately.

CHINA LOW RESOLUTION DATA SETS
Although scaled to 1:1M, these data were either generalised from the high resolution data, described above, or were derived from smaller scale materials in order to create digital cartography that can be used to produce graphical output suitable for publication-sized hard copy. For instance, the coast line depicts only major features, not all small islands that thicken the coastline significantly when printed out at normal page size. Academic discounts of 25%, only, apply to any China Low Resolution Data Sets.

Drainage basins alone, A$750.
Supplied with the Major Rivers and Lakes plus the Grand Canal, as above, or with LUMC main streams. A$1,350.
CHINA PHYSIOGRAPHY
- Contours in meters for any intervals or altitudes [PRC-CON]
- Generated from the USGS 30 Arc Second DEM data, contain unedited anomalies.
Can be supplied with DCW or other base map
coastlines/international boundaries. A$300 per contour level, quantity discounts
for multiple levels.
- Registered DEM images [PRC-DEM]
- Images prepared with set elevation breaks represented with color variations, available in an Albers projection or decimal degrees (WGS84) and registered for use with ARC/INFO, ArcView, and MapInfo, etc. Either DCW or LUMC international boundaries used for clipping. All China, A$250, Provinces and special areas/smanll regions, A$100.
LAND-USE MAP OF CHINA SPATIAL DATA BASES - 1:1M
These datasets were produced under a copyright agreement with the Institute of
Geography and the Science Press, Chinese Academy of Sciences, Beijing. They are now available for commercial purposes as well as academic use and collaboration (the latter is subject to negotiations with the Institute of Geography, CAS).
Academic and other discounts are not available for these LUMC datasets, which are in effect licenced to organisations or research projects on a multiple user basis. Licence costs for large organisations are negotiable.
Most of the information on the 64 1:1,000,000 sheets of the 'Land-use Map of China', produced under the general editorship of Professor Wu Chuan-jun and published by the Science Press in 1990 are available, plus additional ACASIAN assigned drainage basin codes and navigable waterway indentifications.
All data are vailable in ARC/INFO Workstation coverages and export files, ArcView shapefiles, and MapInfo formats.
- Land-use Polygons Covering All of China [CH-LUMC]
- Approximately 165,000 in ten major categories with a total of 55
sub-categories. Coastlines and international boundaries not DCW compatible. Partial coverages for specific areas or individual provinces can be supplied.
All data, A$13,000; provinces A$300 to A$1,500.
- Dense Hydrography for All China [CH-HYLP]
- Approximately 100 Megabytes of data in ARC/INFO coverages (more in most other GIS software formats), includes all
hydrodlogical features on the LUMC including glaciers and marshes, etc. Lines and polygons are coded for display purposes.
Not DCW compatible, but far, far more detailed.
Partial coverages for specific areas or individual provinces can be supplied.
All data, A$13,000; provinces A$300 to A$1,500.
- Additional Hydrography Coding for Navigable Waterways [CH-HYLP_N]
- Only supplied in conjunction with the 'Dense Hydrography' dataset above, these codes identify the navigable waterways of China as shown in a variety of sources and and allow them to be displayed either alone or in contrast to all of the other
waterways and other hydrographic features. All navigation code fields, A$750; portions proportional.
- Additional Hydrography Coding for Drainage Basins [CH-HYLP_D]
- Only supplied in conjunction with the 'Dense Hydrography' dataset above, these codes distinguish the drainage basins identified on the map on page 4 of 'The Population Atlas of China' (Oxford University Press, 1987) plus dozens and dozens more subbasins and some sub-subbasins with 6 digit codes and also coded for display purposes. The mainstreams in each basin, subbasin and sub-subbasin are also identified and coded for display.
The 'Drainage Basin Demarcations for Significant Rivers and Major Tributaries' [PRC-DBS] dataset, described above under China Low Resoultion Data Sets, is included with these codes. All drainage basin code fields, A$1,350; portions proportional.
- Additional Hydrography Coding for Drainage Topology [CH-HYLP_T]
- Only supplied in conjunction with the 'Dense Hydrography' dataset above, these codes identify the the topology of drainage systems in terms of the relations of tributaries to mainstreams within drainage basins.
All topologic code fields, A$5,000;
portions proportional.
- Cities and towns, roads and railroads, and county-level administrative
divisions (ADM3, circa 1980) [CH-CTTR]
