Projection issue in backgroundmaps

[dbrakenhoff]

When adding a backgroundmap the result is shifted slightly relative to data that was already in the EPSG:28992 coordinate reference system. By supplying the correct CRS proj string this issue is fixed. nlmod uses this new modified CRS string by default.

For future reference:

import nlmod

extent = [110_000, 120_000, 485_000, 495_000]
ds = nlmod.get_ds(extent, crs=28992)
gdf_opp_water = nlmod.read.rws.get_gdf_surface_water(ds)

f, ax = nlmod.plot.get_map(ds.extent)
gdf_opp_water.plot(hatch="///", facecolor="none", ax=ax)
nlmod.plot.add_background_map(ax=ax, crs=28992)
