Legality

See also: Restrictions on geographic data in China on Wikipedia

According to the Surveying and Mapping Law of the People's Republic of China, private surveying and mapping activities without authorization[a] are illegal in mainland China. "Since at least 2007, it has been effectively illegal for foreigners to operate a GPS device in China."[1]

China's state media has released a string news articles about illegal mapping efforts as a threat to national security. The article also mentions news which had been announced before, that any foreigner collecting geographical data without permission will be "severely punished".

This seems to outlaw the entire OSM project and any participation or contribution. Presumably the government wouldn't go to the hassle of pursuing lawbreakers who have contributed data so far. However, the law may be actively enforced in Xinjiang, Tibet and near sensitive facilities.[2] "Most of the violations publicized so far have involved [research] in Xinjiang. Working in Tibet, meanwhile, has become almost impossible."[1]

Content regulations/Legality of content

There are some less important laws that manage map content in China. In the context of OSM, it makes the project just a bit more illegal.

  • 公开地图内容表示若干规定 ("some rules on the content presentation of public maps") of 2003 by the Bureau Surveying and Mapping (BSM) prohibits military=*, depth=*, and any airport not on a list of airports for public view. Also some stuff about territorial completeness.
  • 公开地图内容表示补充规定(试行)("supplementary rules on the content presentation of public maps, trial version") of 2009 from the BSM prohibits voltage=*, maxheight=*, maxweight=*, maxwidth=*, surface=* and utility=*. Also no prisons, drug rehabs, dams, or any locations more precise than 50 meters.
  • 地图管理条例 ("map management regulations") from 2015 by the State Council prohibits storing map data out of China. That's the entire OSM right there.

Coordinate system

Most online map services in China, including foreign map services that are available in China, use a set of obscured and transformed coordinates system, "GCJ-02", for their maps in order to comply with instructions from relevant departments. Please note that OSM do not use such kind of coordinate system and thus please do not include data manipulated into such coordinate system or use imagery that are transformed into such coordinate when mapping in OSM. There are however tools to convert GCJ-02 into WGS84 available.

Administrative divisions of China

Main article: China/Boundaries

The administrative division is quite strict in China and the importance and size of a place is almost entirely determined by its administrative level. The general OSM classification (with just city, town, village), however, is not really sufficient to reflect these levels. (Further reading: History of the term City (市) in China)

In order to reflect the Chinese administrative division better, a supplementary tag is used to denote this: place:CN=*. The classification (with hopefully self-explanatory names) is for places, not replacing the standard OSM tagging.

地级行政区/Prefecture level

boundary=administrative + admin_level=5 area

7 Prefecture (地区; dìqū)— These were formerly the dominant second-level division, which is why this administrative level is often called "prefecture-level". However, they were replaced for the most part by prefecture-level cities from 1983 to the 1990s. Today, prefectures exist mostly in Xinjiang and Tibet.
30 Autonomous Prefectures (自治州; zīzhìzhōu)— Are prefectures with one or more designated ethnic minorities. These are mostly to be found in China's western regions.
293 Prefecture-level Cities (地级市; dìjíshì)

place=city + capital=5 node — It form the vast majority of prefecture-level divisions. Prefecture-level cities are generally composed of an urban center and surrounding rural areas much larger than the urban core, and thus are not "cities" but municipal in the strict sense of the term.

3 Leagues (; méng)— are effectively the same as prefectures, but they are to be found only in Inner Mongolia. Like prefectures, leagues have mostly been replaced with prefecture-level cities. The unique name is a holdover from earlier forms of administration in Mongolia.

县级行政区/County level

boundary=administrative + admin_level=6 area

place=city + capital=6 node (The capital of the prefecture-level administrative region use capital=5) (DO NOT USE population=* if population is greater than 400,000)

(as of 2021)

1,301 Counties (; xiàn)— are the most common county-level subjects. Counties have continuously existed since Warring States Period, much earlier than any other level of government In China. Sinology literature, xian often translated as "districts" or "prefectures".
117 Autonomous Counties (自治县; zìzhìxiàn)— are counties with one or more designated ethnic minorities. These analogous to autonomous regions (at the province-level) and prefectures prefecture-level).
414 County-level cities (县级市; xiànjíshì)— are, like prefecture-level cities, not "cities" in the traditional sense of the word, since they are actually large administrative regions that cover both urban and rural areas. It was popular for counties to become county-level cities in the 1990s, though this has since been halted.
977 Districts (市辖区; shìxiáqū)— another type of county-level division. These were formerly the subdivisions of urban areas, consisting of built-up areas only. In recent years, however, many counties have been converted into districts, so that today districts are often just like counties, with towns, villages, and farmland.
49 Banners (; )— which are The same as counties except in name. name is a holdover from earlier forms of administration Mongolia.
3 Autonomous Banners (自治旗; zìzhìqí)— which are The same autonomous counties except in name. name is a holdover from earlier forms of administration Mongolia.
1 Forestry Areas (林区; línqū)— a special county-level subject forestry district currently there is only one forestry area (Shennongjia) located in Hubei province.
1 Special Districts (特区; tèqū)— another special county-level subject exclusively located in Guizhou province.

新区/New Areas

国家级新区/State-level new areas

boundary=administrative + admin_level=7 + place=city or place=suburb depending on population and importance

As of 2019, there are 20 New Areas (新区; xīn qū) in China. Although designated as state-level, they are administratively part of prefecture-level Cities (地级市). As they do not replace counties, and their boundaries may cross county boundaries, they are tagged using a different admin_level=*.

乡级行政区/Township level

boundary=administrative + admin_level=8 area

place=town + capital=8 node (a settlement) or

place=suburb node (part of the settlement)

Public Service Centres (公共服务中心; gōnggòng fúwù zhōngxīn)— comparable to 街道 subdivision.*
8,101 Townships (; xiāng)— in smaller rural areas division they are divided into this subject.
966 Ethnic Townships (民族乡; mínzúxiāng)— in a small one or more designated ethnic minorities rural areas division they are divided into this subject.
21,013 Towns (; zhèn)— in larger rural areas division they are divided into this subject.
8,519 Subdistricts (街道办事处; jiēdàobànshìchù)— in a small urban areas division they are divided into this subject.
11 District Public Offices (区公所; qūgōngsuǒ)— are a vestigial level of government. These once represented an extra level of government between the county- and township-levels. Today there are very few of these remaining and they are gradually being phased out.
153 Sumus (苏木; sūmù)— are the same as townships, but are unique to Inner Mongolia.
1 Ethnic Sumus (民族苏木; mínzúsūmù)— are the same as ethnic townships, but are unique to Inner Mongolia.

村级自治组织/Village level

boundary=administrative + admin_level=10 area

In built-up areas
115k Neighborhood Committees (社区居民委员会; jūmínwěiyuánhùi)
  Neighborhoods / Communities attach to others (社区; shèqū) Use place=quarter
  Neighborhoods / Communities standalone (社区; shèqū) Use place=village
Rural
492k Village Committees ((村民委员会; cūnmínwěiyuánhùi)
  Administrative Villages (行政村; xíngzhèngcūn) Use place=village
   Natural Villages / Village groups (自然村 / 村民小组; zìráncūn / cūnmínxiǎozǔ) Use place=hamlet

Conventions

Name tagging

Road Types

NOTE: This classification is considered too vague. Please talk about it in its talk page.

Housing development (Xiǎoqū)

小区 - panoramio (1).jpg

Tag the boundary with place=neighbourhood and optionally landuse=residential.[3]

For roads within the Xiǎoqū use access restrictions to stop through traffic from being routed through. (access=permissive, access=private, or usually, only for motor vehicles motor_vehicle=private)

Examples: [1] way 453297764, way 298474996

Addresses

Not all addresses will be easy to fit in the OSM standard tags, below is a suggested way. If in doubt, use addr:full. For detailed reference see the addr key page.

Generics in Chinese

When one of the following is present in a name, it is customary to translate them when using name:en, instead of just using Pinyin without accents, e.g. 天安门广场 becomes Tiananmen Square, not Tiananmenguangchang. In case English literature uses a different transliteration, this should prevail.

MapWorld Services (in Chinese) Terms and conditions (服务条款)

information sign

For some countries (even everywhere outside mainland of China) the site may just show a blank page reading: 418 - Sorry, your request has been intercepted because it appears to be an attack.

MapWorld Imagery at zoom levels 16-18 may be used as a reference or confirmation for Bing Aerial/Mapbox Satellite (so do not trace directly from MapWorld!). This is a state-run service and the only service in China where true WGS-84-based[4] Web Mercator Projection is provided.

View image levels 16-18 and Bing Aerial/Mapbox Satellite can be referenced alternately. This is the map service of the country's business, and it's the only thing that can be projected.

**According to the terms and conditions, Tianditu cannot be used for mapping or tracing, please acknowledge the potential copyright issues before you make any progress. You may be blocked by administrator.

According to the current terms, the aerial imagery cannot be used for mapping, and the administrator may ban you.

API Key

MapWorld Imagery API will no longer available without validated API Key after January 1st, 2019. A Mainland of China mobile number (+86) is required while sign up.

Usage/用法

  • In JOSM(recommended), open "imagery preference" and add a TMS layer with the following url:
tms[18]:http://t0.tianditu.gov.cn/img_w/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=img&STYLE=default&TILEMATRIXSET=w&FORMAT=tiles&TILEMATRIX={z}&TILEROW={y}&TILECOL={x}&tk=<your ticket(server)>
  • Or in iD, click "customizing backgroud" and enter the same excluding the prefix tms[18]. That will cause empty tiles beyond the level 18, which is not convenient to do some precise edition, and that is why JOSM or other editor can restrict the zoom level is recommended.

Sentinel-2

Most recent imagery available, very helpful for newly developed areas. See Sentinel-2#Usage_in_editors.
