/filter/byradius/geometry

URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/filter/byradius/geometry

Calculates which geospatial geometry objects from a table intersect a circle with the given radius and center point (i.e. circular NAI). The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input circular NAI restriction specification is also created if a input parameter view_name is passed in as part of the request.

Input Parameter Description

Name	Type	Description
table_name	string	Name of the table on which the filter by radius operation will be performed. Must be an existing table.
view_name	string	If provided, then this will be the name of the view containing the results. Must not be an already existing collection, table or view. The default value is ''.
column_name	string	Name of the geospatial geometry column to be filtered.
x_center	double	Value of the longitude of the center. Must be within [-180.0, 180.0]. The minimum allowed value is -180. The maximum allowed value is 180.
y_center	double	Value of the latitude of the center. Must be within [-90.0, 90.0]. The minimum allowed value is -90. The maximum allowed value is 90.
radius	double	The radius of the circle within which the search will be performed. Must be a non-zero positive value. It is in meters; so, for example, a value of '42000' means 42 km. The minimum allowed value is 0. The maximum allowed value is MAX_INT.
options	map of string to strings	Optional parameters. The default value is an empty map ( {} ). Supported Parameters (keys) Parameter Description collection_name Name of a collection which is to contain the newly created view. If the collection provided is non-existent, the collection will be automatically created. If empty, then the newly created view will be top-level.

Output Parameter Description

The GPUdb server embeds the endpoint response inside a standard response structure which contains status information and the actual response to the query. Here is a description of the various fields of the wrapper:

Name	Type	Description
status	String	'OK' or 'ERROR'
message	String	Empty if success or an error message
data_type	String	'filter_by_radius_geometry_request' or 'none' in case of an error
data	String	Empty string
data_str	JSON or String	This embedded JSON represents the result of the /filter/byradius/geometry endpoint: Name Type Description count long The number of records passing the radius filter. info map of string to strings Additional information. Empty string in case of an error.
