ketiga template json

// mapserver template
[resultset layer=propinsi]
{
  "type": "FeatureCollection",
  "features": [
    [feature trimlast=","]
    {
      "type": "Feature",
      "id": "[id]",
      "nama": "[PROVINSI]",
      "geometry": {
      "type": "MultiPolygon",
      "coordinates": [ {
        "type": "MultiPolygon",
        "coordinates": [[shpxy]]
      }
        ] }
    [/feature]
  ]
}
[/resultset]
