[aweinert-MIT]

Create a python 3.x function to calculate the distance between a set of images and ferry terminals.

• Inputs either a N X 1 imagery UUID or an image itself
• Calculate the distance, in units meters, between the latitude, longitude metadata of the image and all nearby ferry terminal.
• Output a N X 4 column of UUID, image latitude, image longitude, distance to nearest ferry terminal, UUID of nearest ferry terminal

setup.sh will needed to be updated to download USDOT: Ferry Terminals. A default data directory titled /data/USDOT-FerryTerminals should be created to store the data.
