China Coordinate Convertor

中国火星坐标转换命令行工具,用于WGS-84(未偏移坐标), GCJ-02(国家测绘局、高德、谷歌中国地图), BD-09(百度坐标系)三者之间的互相转换,支持文件格式:

  • ESRI Shapefile

  • GeoJSON

    图片名称

安装

推荐使用: pip install coord-convert

或者也可以从源码安装:

git clone https://github.com/sshuair/coord-convert.git
pip install -r requirements.txt
python setup.py install

依赖

  • python3
  • fiona
  • tqdm
  • click

使用方法

注意:火星坐标转换是针对经纬度的转换,因此在进行转换前需要将坐标转换成经纬度;比如web墨卡托(3857)等投影坐标系需要先转成经纬度坐标(4326)

Python API调用

在python程序中调用相应的坐标转换接口

from coord_convert.transform import wgs2gcj, wgs2bd, gcj2wgs, gcj2bd, bd2wgs, bd2gcj 
lon, lat = 120, 40
gcj_lon, gcj_lat = wgs2gcj(lon, lat)
bd_lon, bd_lat = wgs2bd(lon, lat)
print(gcj_lon, gcj_lat) # the result should be: 120.00567568355486 40.0013047896019

命令行调用

火星坐标转换还支持命令行直接对shp、geojson等文件进行转换,比如

~/temp > coord_covert gcj2wgs tests/data/Polyline/polyline.geojson aa.geojson
100%|██████████████████████████████████████████████████████| 219/219 [00:00<00:00, 550.93it/s]

更详细的用法:

convert input china coordinate to another. 
    
    Arguments:
        convert_type {string} -- [coordinate convert type, e.g. wgs2bd]

            wgs2gcj : convert WGS-84 to GCJ-02
            wgs2bd  : convert WGS-84 to DB-09
            gcj2wgs : convert GCJ-02 to WGS-84
            gcj2bd  : convert GCJ-02 to BD-09
            bd2wgs  : convert BD-09 to WGS-84
            bd2gcj  : convert BD-09 to GCJ-02

        src_path {string} -- [source file path]
        dst_path {string} -- [destination file path]


    Example:
        coord_covert wgs2gcj ./examples/data/polygon/polygon_wgs.shp ~/temp/polygon_gcj.shp 

You can’t perform that action at this time.
