Collect data from https://www.lds.org/church/temples/find-a-temple?lang=eng.
-
Copy and paste to a spread sheet, format. Title: temple_data. (there is a link to this spreadsheet above)
-
Use batch geocode (Google, 'batch geocode') to find lat and lon coordinates
-
Run python program.
-
Complile images into a .gif using the following terminal commands:
sudo apt-get install imagemagick
