coord-convert's Introduction

China Coordinate Convertor

**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**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

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 ./tests/data/polygon/polygon_wgs.shp ~/temp/polygon_gcj.shp

coord-convert's Issues

不能转换3857等其它投影坐标系

转换精度有误

从gcj02 -> wgs84，和bd09 -> wgs84，从第5位开始有误，详见测试图片：

该包很好用，唯一的一个瑕疵，希望能尽快修复~

3857-4362

有没有什么方法是能实现web墨卡托3857和4362这两个坐标系的互相转换呢

可以增加对CSV文件格式的支持吗？

影像的转换

使用程序可以进行单点的坐标转换。
大家是如何进行影像的转换的呢？
取4角点坐标，然后仿射变化，实现纠正？
反之都有黑边的情况。

想问大家是如何转换的，谢谢！

Thank you for your help!

A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable.

You are using pip version 19.0.3, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
