API documentation,
Baidu Maps offers maps, street view, satellite imagery, and real-time route planning. It is available via the web browser or as a mobile application.
In the web version, search for a location. To select layers, point your cursor to the bottom-right corner and 3 options will appear (i.e., default map view, satellite image, or street view). Select the layer you wish to explore.
Note that the reference number at the bottom left, e.g., "GS(2023)1234", refers to the year when the image was approved for publication by the relevant government authority, China's State Bureau of Surveying and Mapping. This is not necessarily the year when the image was captured.
Street view
Street views are generally available on the road networks, indicated by the thickened routes. For a static preview, place the cursor onto the route. Click to enter street view mode.
Time machine 时光机
The "time machine" function allows you to access older street view images, going as far back as 2013 (if available). From the current street view image, the time machine function is available at the bottom, indicated by a clock icon.
The Enigma of Coordinates in China
Baidu Maps goes even further in its BD-09 coordinates system, applying additional encryption based on GCJ-02.
Where to get the coordinates in Baidu Maps
When searching for a location on Baidu Maps, the BD-09 coordinates are shown in the URL.
To search by coordinates instead, enter the coordinates (longitude first) and check the box for reverse search using coordinates.
3D models
Open-source researchers can cross-reference with other leading mapping services, including AMap (Gaode Maps) and Tencent Map (QQ Maps).
For open-source researchers accessing Chinese map tools from overseas, Baidu Maps is the only tool that provides street view on the web browser. (Street view is not available on AMap, and is only available in Tencent Map's mobile version.)
(Developer API use may be charged)
Web: any modern web browser
Mobile: iOS and Android (basic functionality is available without registering an account)
Developer Platform: email address and account registration
Researchers and developers should consider several limitations:
Geographical Restrictions: The most detailed coverage is limited to China. Little to no data is available for other countries.
Language Barrier: The user interface is only available in Chinese.
Access Speed: International users will experience slower access speeds or need a Chinese IP address to access certain APIs.

Most of the world uses the coordinate system (colloquially known as Earth coordinates), whereas China uses (Mars coordinates). GCJ-02 uses an encryption algorithm that applies random offsets to the latitude and longitude of locations. Obfuscating the geographic data is for .
Another way to search is: . Search for a location and the BD-09 coordinates are shown in the top-right. Note that in Chinese mapping tools, longitude comes before latitude.
A 3D view is available. Baidu Maps also offers an API for building third-party apps that leverage 3D models and live data:
Note that all three mapping tools use (at least in part) the BeiDou Navigation Satellite System 北斗卫星导航系统 for their satellite and positioning capabilities. BeiDou is the global positioning and satellite technology developed by China, and . The exact ways that BeiDou is leveraged depends on the device, the chip, and the location where the mapping tool is used.
Another tool to compare satellite imagery of China is
See the Bellingcat toolkit's page for some general caveats when working with maps and satellite imagery including censorship and content control.
Privacy Concerns: Like many mapping services, Baidu Maps gathers user data, raising concerns about user privacy. (Concerns about Baidu Maps' collection of user data were raised in a and in an , which named all leading Chinese mapping tools among 33 apps for extensively collecting user data, beyond what is relevant to their service provision.)
