About this API

Amap (Autonavi) is one of China's largest electronic map vendors, fully acquired by Alibaba in 2014. Together with Baidu Maps, controls half of China's map market; integrated by countless apps — Ele.me, Taobao, Cainiao, Didi, shared bike apps. Within China, Amap's data accuracy and real-time performance are nearly unmatched (years of navigation business + Alibaba's resource investment). Open Platform API coverage: Web JS API (frontend maps) + REST API (geocoding/reverse, routing, POI search, real-time traffic) + mobile SDKs (iOS / Android / React Native) + mini-program adaptation. China compliance: must use the SBSM-designated coordinate system (GCJ-02 Mars coordinates); raw GPS WGS-84 data needs conversion. Free individual developer daily quota usually suffices for small projects; commercial high-volume needs paid plans.

FAQ

Amap vs. Baidu Maps?+

Amap: more accurate data + more professional UI (strong navigation). Baidu: larger daily user base + mass-market UI. App integration is split roughly 50/50.

How to handle coordinate systems?+

GPS gives WGS-84; must convert to GCJ-02 (Amap/Baidu national standard) for correct display on domestic maps. Amap SDK has built-in conversion.
