The 3 and 1 arc second data are the SRTM 1x1 degree tiles from NASA. Note: The 3 and 1 arc second grids only extend to latitudes ±60˚ and are only available over land. When these grids are accessed as @earth_relief_01s or @earth_relief_03s we will automatically up-sample the relevant @earth_relief_15s tiles to fill in the missing ocean values. If you just want the original land-only SRTM tiles you may use the special names @srtm_relief_03s or @srtm_relief_01s instead.
Currently, the load_earth_relief() function can load 01s and 03s Earth relief grid, but can't load the original land-only SRTM grid.
It seems easy to add the feature. We just need to add a new parameter use_srtm (default to False) to the load_earth_relief function.
If resolution="01s" or resolution="03s", we check the value of use_srtm to determine the remote file prefix (either earth_relief_ or srtm_relief_).
Are you willing to help implement and maintain this feature? Yes, but volunteers are welcomed.
