Open Data from OpenTreeMap: Visualizing temporal data with CartoDB’s Torque

I just wrote up a meaty Labs post on my idea to visualize tree, species, and user edits over time within exported data from PhillyTreeMap.org, and already covered all the joining, formatting, converting, and uploading necessary to get to this point, along with some simple visualizations at the end. If you haven’t read it, go ahead. I’ll wait here. Because with this post I’m diving straight in to the temporal visualization features of CartoDB’s Torque.

Briefly, though, to reiterate: What are my goals for visualizing the 2 years of PhillyTreeMap user edits over time? I wanted to create something parallel to Mark Headd’s homicide data visualization (also done with Torque) but that told a story over time that was more uplifiting. (What’s more uplifting than trees?) I also hoped my visualization would give us a rough idea of what neighborhoods and areas around Philadelphia have the most active PhillyTreeMap user edits, as well as what times of year seem most active. One could use that knowledge to determine and plan where or when to do outreach about PhillyTreeMap or the programs of our partners, like PHS Tree Tenders. What neighborhoods don’t have many user edits? When does participation drop off? On the flip side, where and when are urban forestry efforts succeeding in engaging the community? A time based spatial visualization can help us answer those questions – and look really cool in the process!
