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, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
view_name string If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing 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

If true, a unique temporary table name will be generated in the sys_temp schema and used in place of input parameter view_name. This is always allowed even if the caller does not have permission to create tables. The generated name is returned in qualified_view_name. The default value is false. The supported values are:

  • true
  • false
collection_name [DEPRECATED--please specify the containing schema for the view as part of input parameter view_name and use /create/schema to create the schema if non-existent] Name of a schema for the newly created view. If the schema provided is non-existent, it will be automatically created.

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_response' 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. The default value is an empty map ( {} ).

Possible Parameters (keys) Parameter Description
qualified_view_name The fully qualified name of the view (i.e. including the schema)

Empty string in case of an error.
