[15], A marker with GCJ-02 coordinates will be displayed at the correct location on a GCJ-02 map. Google Earth also uses WGS-84 to display the satellite imagery. Therefore, the GPS shift problem does not apply.

The latitude is the position relative to the equator, specifying the north-south position. [31][13] Baidu provides an API call to convert from Google or GPS (WGS-84), GCJ-02, BD-09, MapBar [zh] or 51ditu [zh] coordinates into Baidu or GCJ-02 coordinates. Since ``bad = worsen(good)`` is close to ``good``. ][citation needed] However, the open-source "reverse" transformations make use of the properties of GCJ-02 that the transformed coordinates are not too far from WGS-84 and are mostly monotonic related to corresponding WGS-84 coordinates:[33][14], The rough method is reported to give some 1~2 meter accuracy for wgs2gcj,[24] while the exact (fixed point iteration) method is able to get "centimeter accuracy" in two calls to the forward function. geographic information in the People's Republic of China, International Terrestrial Reference System, Spatial Reference System Identifier (SRID), Basic security processes for electronic navigational maps, "Surveying and Mapping Law of the People's Republic of China", "Restricciones al trabajo con información geográfica online en China", "Surveying and Mapping Law of the People's Republic of China— National Administration of Surveying, Mapping and Geoinformation", "China cracks down on illegal online map services to protect state security", "China fines UK students for 'illegal map-making, "China issues new rules on Internet map publishing", "If You're a Foreigner Using GPS in China, You Could Be a Spy", "Why your camera's GPS won't work in China (maybe)", "A package for geocoding, reverse geocoding and coordinate transformations between WGS-84, GCJ-02 and BD-09 coordinate systems", "科研要为祖国和人民服务――记中国测绘科学研究院地图学与地理信息系统研究所党支部书记、所长李成名", "Transform coordinates between Earth (WGS-84) and Mars in China (GCJ-02)", "The Deviation of China Map as a Regression Problem", "make gcj2wgs_exact() much faster, by using fixed…", "The government charges Chinese companies for the "shift correction" feature", "Nokia Here street map and satellite map both use GCJ-02 coordinates", "Apple Shares Google China Map Partner in Win for AutoNavi: Tech", "Google China street map uses GCJ-02 coordinates", "Google China satellite imagery uses GCJ-02 coordinates", "Google.com satellite imagery uses WGS-84 coordinates", "Could you please correct the offset in China due to GCJ-02 coordinate?

The Google.com street map is offset by 50–500 meters from its satellite imagery,[9][19] while the Google.cn map is not. Between 2006 and 2011, the authorities pursued nearly 40 illegal cases of mapping and surveying.

[3], According to articles 7, 26, 40 and 42 of the Surveying and Mapping Law of the People's Republic of China, private surveying and mapping activities have been illegal in mainland China since 2002.

publishing, without authorization, significant geographic information and data concerning the territorial air, land and waters, as well as other sea areas under the jurisdiction of the People's Republic of China. [1] Consequences of the restriction include fines for unauthorized surveys, lack of geotagging information on many cameras when the GPS chip detects a location within China, incorrect alignment of street maps with satellite maps in various applications,[2] and seeming unlawfulness of crowdsourced mapping efforts such as OpenStreetMap. t Foreign individuals or organizations that wish to conduct surveying must form a Chinese-foreign joint venture.[1]. # Represent coordinates with complex numbers for simplicity. First seen in geoChina/R/cst.R (caijun 2014). Authorized providers of location-based services and digital maps (such as AutoNavior NavInfo) must purchase a "shift correction" algorithm that enable… The PRC is a single-party state governed by the Chinese Communist Party, with its seat of government in the capital city of Beijing.

The latitude and longitude of China have been calculated based on the geodetic datum WGS84. Scripts are disabled by your browser. Under One Country Two Systems, legislation in mainland China does not apply in Hong Kong and Macau SARs and there are no similar restrictions in the SARs. a [note 1][34][33] Since the two properties ensure some basic functionality of the coordinate system, it is unlikely that the methods will change with new coordinate systems. The geographic coordinate system enables any place in the world to be located using its latitude and longitude. Technical spatial processing must be applied to electronic navigational maps prior to publication, sales, redistribution, and usage. The law prohibits. [original research? [35] Satellite imagery and user-contributed street map data sets, such as those from OpenStreetMap also display correctly because they have been collected using GPS devices (albeit technically illegally - see Legislation). [22], Despite the secrecy surrounding the GCJ-02 obfuscation, several open-source projects exist that provide conversions between GCJ-02 and WGS-84, for languages including C#,[23] C, Go, Java, JavaScript, PHP,[24] Python,[25] R,[14] and Ruby. google.cn/maps (formerly Google Ditu) uses the GCJ-02 system for both its street maps[38] and satellite imagery.

On the left we have just the map of the area. ][citation needed] The BD-to-GCJ code works in a manner much like the rough method, except that it removes the explicitly-applied constant shift of ~20 seconds of arc on both coordinates first and works in polar coordinates like the forward function does. This poses problems to users travelling across the border, especially visitors not aware of the issue. [4] The media has reported on other cases of unlawful surveys: As a consequence, major digital camera manufacturers including Panasonic, Leica, FujiFilm, Nikon and Samsung restrict location information within China. Some features of this website will not work. The PRC is a single-party state governed by the Chinese Communist Party, with its seat of government in the capital city of Beijing. The latitude and longitude of China have been calculated based on the geodetic datum WGS84. Chinese regulations mandate that approved map service providers in China use a specific coordinate system, called GCJ-02.
