How to Setup Geojson as Datasource in TileStache

Question

I have successfully installed TileStache in my server. Now I have a geojson file and want to serve it through TileStache. I am new to TileStache and I can't find a clear explanation of how to setup a Geojson in TileStache. Best explanation I can found is here, but it uses a shp file as the datasource.

I want to know how to set it using a Geojson as the datasource.

Edit

I tried adding a tes layer to the config file, so my config file looks like this:

{
  "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": []
                }
        }
  }
}

When I tried to run using tilestache-server.py -c /etc/TileStache/tilestache.cfg, it gives me error like this:

I can't figure out what is wrong.

Answer 1

ImportError: No module named osgeo

You are missing the GDAL library. It can be quite tricky to install, I got it working on Ubuntu 14.04 by using the PPA ppa:ubuntugis/ubuntugis-unstable, read the instructions in this post over at the GIS Stackexchange.
