wradlib.georef.raster.get_raster_elevation#
- wradlib.georef.raster.get_raster_elevation(dataset, resample=None, **kwargs)[source]#
- Return surface elevation corresponding to raster dataset
The resampling algorithm is chosen based on scale ratio
- Parameters:
dataset (
osgeo.gdal.Dataset
) – raster image with georeferencing (GeoTransform at least)resample (
gdal:osgeo.gdalconst.ResampleAlg
) – If None the best algorithm is chosen based on scales. GRA_NearestNeighbour = 0, GRA_Bilinear = 1, GRA_Cubic = 2, GRA_CubicSpline = 3, GRA_Lanczos = 4, GRA_Average = 5, GRA_Mode = 6, GRA_Max = 8, GRA_Min = 9, GRA_Med = 10, GRA_Q1 = 11, GRA_Q3 = 12kwargs (
dict
) – keyword arguments passed towradlib.io.dem.get_srtm
- Returns:
elevation (
numpy.ndarray
) – Array of shape (rows, cols, 2) containing elevation
