rnet.coordinates.idw_query

rnet.coordinates.idw_query(points, crs, *paths, r=0.001, p=2, return_xy=False)

Query elevations of two-dimensional points via IDW interpolation.

Parameters

pointsndarray, shape (N, 2)

Points whose elevations are queried.

crsint

EPSG code of CRS in which point coordinates are represented.

*pathsstr

Path(s) to TIF file(s) storing elevation data.

rfloat, optional

Search radius for nearby points in degrees. The default is 0.001.

pint, optional

Power setting for IDW interpolation. The default is 2.

return_xybool, optional

If True, \((x, y, z)\) coordinates are returned. Otherwise, only \(z\)-coordinates are returned. The default is False.

Returns

elevationsndarray, shape (N,)

Array of elevations where elevations[i] is the elevation at points[i].
