hydromt.gis_utils.nearest

hydromt.gis_utils.nearest(gdf1: GeoDataFrame, gdf2: GeoDataFrame) → Tuple[ndarray, ndarray]

Return the index of and distance [m] to the nearest geometry in gdf2 for each geometry of gdf1. For Line geometries in gdf1 the nearest geometry is based line center point and for polygons on its representative point. Mixed geometry types are not yet supported.

Note: Since geopandas v0.10.0 it contains a sjoin_nearest method which is very similar and should.

Parameters:

• gdf1 (geopandas.GeoDataFrame) – Source gdf1 and destination gdf2 geometries.

• gdf2 (geopandas.GeoDataFrame) – Source gdf1 and destination gdf2 geometries.

Returns:

• index (ndarray) – index of nearest gdf2 geometry

• dst (ndarray of float) – distance to the nearest gdf2 geometry
