Google Geocoding API with a Database and Visualization on Google Maps

Hits: 302

Today I will use the Google Geocoding API with a database, and visualize the mapping data on Google Maps. In this project, I have a list of university names with no location information, and I will proceed to add location coordinates to the universities using the Google Geocoding API, load those university names with location data into a database, then visualize that data on Google Maps. Here are the university names in where.data (I added Saint Mary’s University in Halifax in the second row- Go Huskies!):

 

I then run the Python script geoload.py to lookup all of the university entries in where.data, call on the Google Geocoding API to add location coordinates, and place all of this data into a database called geodata.sqlite:

I then run geodump.py to read the database and produce where.js:

Finally, I open where.html to visualize the location markers in Google Maps:
