cntms

Tile Map Server reverse proxy with coordinates regularization.

This TMS proxy solves the problems that map services in China geneally have distorted coordinates. It stitches the upstream tiles to make standard EPSG:3857 tiles. This proxy also caches tile images.

Supports: Baidu, Tencent, Gaode, Google, GeoQ, Tianditu, OpenStreetMap and ArcGIS MapServer.

Edit tmsapi.ini to set listen address, port, cache size, and upstream APIs.

Use this software at your own risk.

You can use leaflet.ChineseCRS on Leaflet web maps without this proxy.

纠偏瓦片地图代理，可修复图块中 GCJ02、BD09 等坐标系的偏移。可用于 GIS 软件、网页地图等。

配置文件在 tmsapi.ini。请自行架设服务器，请勿滥用，风险自担。
