        specified explicitely with valid values "folium" and "ipyleaflet" .

        In case of folium backend, tiles parameter is passed directly
        to folium.Map() which supports several built-in tilesets

        In case of ipyleaflet, only the tileset name and not the URL is
        currently supported.

        Raster and vector data are always reprojected to Pseudo-Mercator.
        With use_region=True or saved_region=myregion, the region extent
        is reprojected and the number of rows and columns of that region
        is kept the same. This region is then used for reprojection.
        By default, use_region is False, which results in the
        reprojection of the entire raster in its native resolution.
        The reprojected resolution is estimated with r.proj.
        Vector data are always reprojected without any clipping,
        i.e., region options don't do anything.
