Geo Distance Calculation using GeoPy Python package

This worklow demonstrates the usage of geopy python package for distance calculation given the GPS coordinates.

The Python Script node uses the python package geopy for distance calculation. The conda environment propagation node makes sure the python environment required for the execution of the Python Script node is made available at the user's system.

The geopy package is not included in the Bundled environment that comes with the Python Script node, which is why we create a new environment with geopy package and ship this environment using the Conda Environment Propagation node.
