Extracting geodata from OpenStreetMap with Osmfilter

Extracting geodata from OpenStreetMap with Osmfilter

A guest post by Hans Hack

When working on map related projects, I often need specific geographical data from OpenStreetMap (OSM) from a certain area. For a recent project of mine, I needed all the roads in Germany in a useful format so I can work with them in a GIS program. So how do I do I get the data to work with? With a useful little program called Osmfilter.

Part 2 | Code

A few weeks ago, we discovered it’s possible to export WhatsApp conversation logs as a .txt file. It’s quite an interesting piece of data, so we figured, why not analyze it? So here we go: A code-along R project in two steps.

  1. Cleaning the data: That’s what this part is for. We’ll get the .txt file ready to be properly evaluated.
  2. Visualizing the data: That’s what we’ll talk about in part two — creating some interesting visuals for our chat logs.
