intersects#
- intersects(input: GeoDataFrame, other: GeoDataFrame, buffer_on_input: float | None = None) GeoDataFrame [source]#
Select the polygons of the input GeoDataFrame that intersects the other one and return them.
A buffer can be added on the input GeoDataFrame to be sure the intersection is ok. For example, when dealing with polygons and points on their borders, sometimes the points fall a tiny bit outside the polygon boundary and is not considred as intersecting.
gpd.intersects
algorithm applied to whole GeoDataFrames.- Parameters:
input (gpd.GeoDataFrame) – Input GeoDataFrame from which the polygons will be selected
other (gpd.GeoDataFrame) – Other GeoDataFrame from that will intersect the first one
buffer_on_input (float) – Buffer size on thhe input GeoDataFrame
- Returns:
Polygons of the input that intersects the other GeoDataFrame
- Return type:
gpd.GeoDataFrame
