arcgis.geometry.filters module¶
Functions to filter query results by a spatial relationship with another geometry Used when querying feature layers and imagery layers.
intersects¶
-
arcgis.geometry.filters.intersects(geometry, sr=None)¶ filters results whose geometry intersects with the specified geometry
USAGE EXAMPLE: Select the gas lines that intersect a specific freeway feature, United States Interstate 15. from arcgis.geometry import Geometry from arcgis.geometry.filters import intersects # select a filter feature to construct its geometry rte15_fset = freeway_lyr.query(where="ROUTE_NUM = 'I15'") rte15_geom_dict = rte15_fset.features[0].geometry rte15_geom_dict['spatialReference'] = freeway_sr rte15_geom = Geometry(rte15_geom_dict) # construct a geometry filter using the filter geometry flyr_filter = intersects(rte15_geom, sr=freeway_sr) # query a feature layer for features that meet filter criteria gas_lines_I15 = gas_line_lyr.query(geometry_filter=flyr_filter)
contains¶
-
arcgis.geometry.filters.contains(geometry, sr=None)¶ Returns a feature if its shape is wholly contained within the search geometry. Valid for all shape type combinations.
crosses¶
-
arcgis.geometry.filters.crosses(geometry, sr=None)¶ Returns a feature if the intersection of the interiors of the two shapes is not empty and has a lower dimension than the maximum dimension of the two shapes. Two lines that share an endpoint in common do not cross. Valid for Line/Line, Line/Area, Multi-point/Area, and Multi-point/Line shape type combinations.
envelope_intersects¶
-
arcgis.geometry.filters.envelope_intersects(geometry, sr=None)¶ Returns features if the envelope of the two shapes intersects.
index_intersects¶
-
arcgis.geometry.filters.index_intersects(geometry, sr=None)¶ Returns a feature if the envelope of the query geometry intersects the index entry for the target geometry.
overlaps¶
-
arcgis.geometry.filters.overlaps(geometry, sr=None)¶ Returns a feature if the intersection of the two shapes results in an object of the same dimension, but different from both of the shapes. Applies to Area/Area, Line/Line, and Multi-point/Multi-point shape type combinations.
touches¶
-
arcgis.geometry.filters.touches(geometry, sr=None)¶ Returns a feature if the two shapes share a common boundary. However, the intersection of the interiors of the two shapes must be empty. In the Point/Line case, the point may touch an endpoint only of the line. Applies to all combinations except Point/Point.
