Map projections and features

Compare different map projections and add geographic features.

Why UltraPlot here?

UltraPlot’s GeoAxes supports many projections via proj and makes adding features like land, ocean, and borders trivial via format().

Key functions: ultraplot.subplots(), ultraplot.axes.GeoAxes.format().

fig, axs = uplt.subplots(ncols=3, proj=projs, refwidth=3, share=0)

# Format all axes with features
# land=True, coast=True, etc. are shortcuts for adding cartopy features
