ogr2ogr kml

 将kml文件转换为dxf文件

ogr2ogr -t_srs EPSG:2385 -f DXF lhk_fbd.dxf doc.kml

更新：以上方法会出错，不知道原因
01 未解决
02 多出的字段是因为libkml
03 OGR_SKIP

ogrinfo -al --config OGR_SKIP LIBKML  qyl.kml

ogr2ogr   --config OGR_SKIP LIBKML  -t_srs EPSG:2436 -f DXF qyl.dxf qyl.kml

set a socks proxy with git for the http transport

git config --global http.proxy 'socks5://127.0.0.1:1081'

set a socks proxy for curl: just add proxy=socks5://127.0.0.1:1081 to ~/.curlrc.
