参考文件主要是Shp2osm:https://wiki.openstreetmap.org/wiki/Shp2osm
最主要部分是:
FOR /R .\ %G IN (*_out.shp) DO shp2osm.pl "%~dpnG" > "%~dpnG.osm"
但是想要执行这个命令没想象中的那么简单,还要经过好多步骤!!而且网上也没有这个Shp2osm转换教程,在百度上我这算是首篇教程了吧!下面来听我慢慢讲解吧。
1、shp2osm.pl这个是.pl文件,perl语言文件的源程序的扩展名,所以首先要安装perl,我用的是Win7系统!
安装Perl教程很多,可以百度搜索。https://jingyan.baidu.com/article/4b52d702e3b86afc5c774ba4.html
2、然后用cmd命令行cd到shp所在文件夹路径,执行FOR /R .\ %G IN (*_out.shp) DO shp2osm.pl "%~dpnG" > "%~dpnG.osm"
命令,还需要shp2osm.pl文件!

3、运行报错
需要perl安装模块,在网上搜索资料。
安装模块方法参考:https://blog.csdn.net/czz1141979570/article/details/78697219
第一种方法是从CPAN上下载您需要的模块,手工编译、安装。
第二种方法是联上internet,使用一个叫做CPAN的模块自动完成下载、编译、安装的全过程。
可是安装了两三个模块之后再安装autovivification模块就报错了,c不是内部或外部命令还有link不是内部或外部命令,用这两种方法安装都安装不了!结果又找资料发现了一个神器!perl package manager,在这个软件可以直接安装模块!早知道就不用那么费劲用命令行安装了。
操作步骤:
1、鼠标右键点击选择安装或者卸载;
2、File→Run Marked Actions Ctrl+Enter,然后就执行安装,安装成功就行了!
写到最后:最后执行命令不报错了,需要的模块也安装好了,OSM格式文件便转换成功了。
