easysnowdata.plotting.add_outline#

easysnowdata.plotting.add_outline(ax: Any, gdf: Any, crs: Any = None, *, label: str | None = None, keep_extent: bool = True, **plot_kwargs: Any) → Any[source]#

Draw gdf (boundaries, basins, glaciers) over a map, in the map’s CRS.

Parameters:

ax – Axes a map was drawn on (by map(), categorical() or points()).
gdf – Polygons or lines; reprojected to the map’s CRS.
crs – The map’s CRS. Defaults to the one finish_map() recorded on ax, else EPSG:4326.
label – Legend entry for the outlines.
keep_extent – Keep the map’s extent rather than zooming out to the whole outlines (a state or country usually reaches far beyond the map).
**plot_kwargs – Passed to geopandas.GeoDataFrame.plot(); the defaults are edgecolor="black", linewidth=0.8 and no fill. Pass column= (with cmap=, legend= …) or facecolor= to fill the polygons as well.

Returns:
