Attribute Search and Layer Download
Search for custom geometries by attribute filter, or download complete layer.
|app_id||Yes||A URL-safe encoded string obtained during the application registration. See Acquiring Credentials for information on getting credentials.|
|app_code||Yes||A URL-safe encoded string obtained during the application registration. See Acquiring Credentials for information on getting credentials.|
|layer_id||Yes|| Layer ID identifying the layers to be searched. Can also be a comma separated list of layers. Layer names are not case sensitive. The maximum length of a layer name and the permitted characters can be lookup up in the service via |
|geom||No||full or none. Specifies the geometry representation in the result. Default = full. |
Columns value for the geometry are available as defined variables.
When specified, only geometries where expression evaluates to true will be returned.
Example: filter=RATING > 3 && NAME != 'MyPlace23' && NAME.startsWith('Food')
Parameter value must be url encoded when using special characters.
This filter expression is applied after the spatial filtering, hence only to few geometries. Only for the
|start_geometry_id||No|| To paginate huge responses, this parameter specifies the lowest geometry id to be returned. If geometry ids are not known, then retrieve the first page using zero, and to retrieve subsequent pages then request highest geometry of current page + 1 (it doesn't matter whether this geometry id actually exists or not). Use this parameter together with |
The maximum number of geometries in the response. If more geometries satisfy the search/filter criteria, they will be suppressed.
It is undefined, which of the matching geometries are returned, unless this parameter is used together with
|callback||No||Specifies the function used to wrap the JSON response.|
|meta||No||Send with value=1 to get the response geometries framed with meta information like layer and tile id. Default = no meta data.|
