VertiGIS Studio Web supports the GetFeatureInfo Identify request for WMS layers.

Identify is supported only when all of the following conditions are met:

•The response contains point geometries only.

•The layer featureInfoFormats is one of the following:

•application json

•application/geojson

•text/xml

If the layer contains multiple supported featureinfoFormats, the WMS layer automatically uses the first supported format detected. Refer to Esri's WMSLayer documentation for more information.

•The response structure matches one of the expected formats described below.

application/json and application geojson

For application/json and application/geojson, the expected response format is:

{
  "features": [
    {
      "properties": {
        "colour": "red"
      },
      "geometry": {
        "type": "point",
        "coordinates": [1, 2, 3]
      },
      "layerName": "layer name",
      "id": "abc"
    }
  ]
}

Data Dictionary

Sample Response: application/geojson FeatureCollection

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": null,
      "properties": {
        "OBJECTID": "12322159",
        "Straßenname": "A 8"
      },
      "layerName": "strassennetz"
    }
  ]
}

text/xml

For text/xml, the expected response format may be either:

•a FeatureInfoResponse containing FIELDS elements, or

•a FeatureCollection

The expected format can be either a FeatureCollection or a FeatureInfoResponse with FIELDS tags. See this article for more information.
