Property Details
<String
StringTwo-digit country code. For example: "US".
<String
StringOptional string that denotes the ID of a dataset associated with a particular country.
<Number
NumberOptional integer value where you can limit the number of features that are returned from the geographyQuery. If
null, the server will default to 1000. <Number
NumberOptional integer that specifies the level of generalization of the geometries. A value of 0 returns the most detailed and 6 is most generalized. Some geography layers, like 'countries', do not support returning highly detailed geometries.
Known values:
0|1|2|3|4|5|6Default value:
0<String[]
String[]Array of geography IDs. Use this property to return attributes and/or geometries for standard geographic areas for administrative areas where you already know the ID, for example, if you know the Federal Information Processing Standard (FIPS) Codes for a U.S. state or county; or, in Canada, to return the geometry and attributes for a Forward Sortation Area (FSA). Note: only returns features from layers specified in the geographyLayerIDs property.
<String[]
String[]Array of geography layer IDs.
<SpatialReference
SpatialReferenceDetermines spatial reference for output geometry if returnGeometry is set to true.
<Boolean
BooleanUse this parameter to return all the geometries as points. For example, you could return all U.S. ZIP Codes as centroids. Only applies if the returnGeometry property is also set to true.
Known values:
true | falseDefault value:
false<Boolean
BooleanDetermines whether response will also include geometries.
Known values:
true | falseDefault value:
false<Boolean
BooleanOptional boolean to enable fuzzy search. See the REST API for details about using fuzzy logic.
Known values:
true | falseDefault value:
false<String
StringA where clause for the query. Use this property to query for specific areas, for example, all U.S. counties that contain the word "orange".
Optionally, you can specify to search by ID or by Name, for example:
Optionally, you can specify to search by ID or by Name, for example:
query.where = 'ID:06069'
or
query.where = 'NAME:"Orange County"'.
- Notes
- Use the geographyLayerIDs property to define which layers are being searched. To achieve optimal performance, it is strongly recommended that at least one layer is defined in the geographyLayerIDs property. If no geographyLayerIDs are provided, all standard geography layers will be searched within sourceCountry. This will adversely affect performance.
- If the useFuzzySearch property is set to true, all words submitted with geographyQuery will be searched with fuzzy logic. If it is set to false, a standard text search is performed for all text submitted.
- Searches within the geography query are not case sensitive.
