• isobands: Xarray to GeoPandas Contours: Python library that converts a 2D xarray DataArray into filled contour polygons in a GeoPandas GeoDataFrame, using GDAL for contour generation and supporting explicit levels, equal intervals, or data-driven breaks (e.g. quintiles). Released by Ben Welsh as a spinoff of the Reuters Climate Monitor, with examples rendering the output via MapLibre and OpenStreetMap for web maps. Related: Cartography, Web_Mapping. Keywords: XArray, isobands, contours, GeoPandas, GDAL, Reuters, MapLibre
