Reverse Geocode a Set of Lat-Long Coordinates to City + Country

This tutorial demonstrates how to reverse geocode a set of latitude-longitude coordinates to city and country using Python and the Google Maps API.

I have previously written about my GPS location data from this summer’s travels. The data set, gathered with the OpenPaths app, contains lat-long coordinates and timestamps. Without city or country data, any visualizations would be very simplistic because all I have is coordinates and timestamps. It would be nice to reverse geocode these coordinates to add city and country data to each point. Then, I could create richer, more informative marker popups that include this new geographical information.

Visualizing Summer Travels Part 2: CartoDB

This post is part of a series on visualizing data from my summer travels.

I recently discussed OpenPaths and my goals in visualizing location data from my summer travels. In this post, I’ll explore visualizing this dataset with CartoDB. The OpenPaths data from my summer travels, which I’ll be working with in these examples, is available here and I discuss how I reverse-geocoded it here. CartoDB is a simple cloud-based tool for building web maps. You can import data through their web-based dashboard and quickly turn it into a dynamic map or visualization.

Visualizing Summer Travels Part 1: OpenPaths

This post is part of a series on visualizing data from my summer travels.

Oscar Levant once said, darkly, that “happiness isn’t something you experience; it’s something you remember.” We humans have a way of constructing and reconstructing experiences and memories through the methods by which we recall them. The endlessly repeated anecdote from your vacation in Italy eventually becomes emblematic of the larger trip. The photograph on the wall from your wedding day becomes a synecdoche for the entire event.

I spent the past two months in Europe and documented my travels through a set of photographs which have become emblematic, for me, of packages of experiences from different places. However, they are often skewed and selective, telling only one deliberate perspective of a wider, richer experience. Another way to remember and reminisce about one’s travels is through maps. Where did I go? What path did I take? How did the parts of the trip fit together? The answers to these questions are useful in revealing another perspective of the larger experience.
