Query service

The query service or operation is used to get filtered data as a JSON file from the map service. The query is always specific to a layer.

The result of this operation is a feature set. This feature set contains feature objects including the values for the fields requested by the user. For layers, if you request geometry information, the geometry of each feature is also returned in the feature set.

Note:  All the options on the left side are only available in the API. Any user-defined or custom parameters will be ignored.
