Return topography maps (see list below) at model resolution.

Based on gridded elevation data input.

The following topography maps are calculated:

elevtn : average elevation [m]
lndslp : average land surface slope [m/m]

Parameters:

ds (xarray.DataArray) – Dataset containing gridded flow direction and elevation data.
ds_like (xarray.DataArray) – Dataset at model resolution.
elevtn_name (str, optional) – Name of elevation [m] and land surface slope [m/m] variables in ds
lndslp_name (str, optional) – Name of elevation [m] and land surface slope [m/m] variables in ds
method (str, optional) – Resample method used to reproject the input data, by default “average”

Returns:

ds_out (xarray.DataArray) – Dataset containing gridded hydrography data
flwdir_out (pyflwdir.FlwdirRaster) – Flow direction raster object.
