Download a sample Surfer grid file

fname = 'surfer-grid.grd'
url = 'https://github.com/OpenGeoVis/PVGeo/raw/main/tests/data/{}'.format(fname)
filename, _ = examples.downloads._retrieve_file(url, fname)
dem = SurferGridReader().apply(filename)

Apply a filter to the DEM to have realistic topography

warped = dem.warp_by_scalar(scale_factor=300.0)
warped.plot(cmap='terrain')
