Dissolve polygons in GeosPandas
PyGeos: ... Arrays of geometries can be operated on with almost zero Python interpreter overhead, leading to performance increases of up to 100 times compared to current shapely or geopandas usage. I aim to keep the API (and performance) of PyGEOS close to that of PostGIS: the de facto standard library of geospatial analysis on large datasets.
