Question

我已成功在我的服务器中安装了TileStache。现在我有一个geojson文件，并希望通过TileStache提供它。我是TileStache的新手，我无法找到如何在TileStache中设置Geojson的明确解释。我能找到的最佳解释是here，但它使用shp文件作为数据源。

我想知道如何使用Geojson作为数据源来设置它。

修改

我尝试在配置文件中添加tes图层，因此我的配置文件如下所示：

{
  "cache":
  {
    "name": "Test",
    "path": "/tmp/stache",
    "umask": "0000"
  },
  "layers":
  {
    "osm":
    {
        "provider": {"name": "proxy", "provider": "OPENSTREETMAP"},
        "png options": {"palette": "http://tilestache.org/example-palette-openstreetmap-mapnik.act"}
    },
    "example":
    {
        "provider": {"name": "mapnik", "mapfile": "examples/style.xml"},
        "projection": "spherical mercator"
    },
        "tes":{
                "provider": {
                        "name": "vector", "driver": "GeoJSON",
                        "parameters": {"file": "tes.geojson"},
                        "properties": []
                }
        }
  }
}

当我尝试使用tilestache-server.py -c /etc/TileStache/tilestache.cfg运行时，它会给出如下错误：

ImportError: No module named osgeo

我无法弄清楚出了什么问题。

Answer 1

ImportError：没有名为osgeo的模块

您错过了GDAL library。安装起来非常棘手，我使用PPA ppa:ubuntugis/ubuntugis-unstable在Ubuntu 14.04上工作，在GIS Stackexchange上阅读this post中的说明。
