win7下使用TileStache生成geojson格式的Tiles

1.首先安装python2.6并配置环境变量

2.安装Setup tools（方面安装其他软件）和GDAL

3.使用Setup tools安装TileStache，ModestMaps，PIL（TileStache依赖于这两项）

easy_install tilestache easy_install PIL easy_install ModestMaps

4.在下载的TileStache中的文件夹中配置cfg文件

{
  "cache":
  {
    "name": "Disk",
    "path": "/tmp/stache",
    "umask": "0000"
  },
  "layers":
  {
    "postgis":
     {
       "provider": {"name": "vector", "driver": "PostgreSQL",
                         "parameters": {"dbname": "postgis", "user": "postgres","password":"postgres",
                                "table": "mainroad"}}
                        }
     }
  }
}

5.然后用tilestache-seed进行切片

6.结果
