GeoPandas is an open source project to make working with geospatial data in python easier. GeoPandas extends the datatypes used by pandas to allow spatial operations on geometric types.

Geometric operations are performed by shapely. Geopandas further depends on fiona for file access and descartes and matplotlib for plotting.

If you're having trouble running or installing geopandas, it is recommended that you use conda to install geopandas into a new conda environment. When installing the GIS stack, it's recommended that you pull all of the dependencies from a single channel (e.g., only from the default channel or only from conda-forge):

> conda create --name=gis python=3.7 geopandas --channel=conda-forge

Calculate all distances between two GeoDataFrame (of points) in GeoPandas

This is quite simple case, but I did not find any easy way to do it so far. The idea is to get a set of distances between all the points defined in a GeoDataFrame and the ones defined in another GeoDataFrame. import geopandas as gpd import pandas as…
