This intermediate to advanced level workshop will take new cartographers and show them unique and interesting data visualizations methods and how to create them with open tools and OpenStreetMap data. If you're looking to advance your portfolio, this is a great opportunity to learn from artists and advanced cartographers.
- Advanced TileMill Techniques: TileMill lets you go beyond simple style changes to make heat maps, elevation maps, maps from outerspace, and pirate maps. Learn how to create any map style you can dream up in this session. Presented by Dane Springmeyer, 9:00 am.
- How to Put 2.7 Billion Dots on a Map: OpenStreetMap's collection of GPS traces is full of interesting information about the world, but is very hard to work with because it is so huge. This session will walk through how to make it and other similarly large data sets accessible on the web. Presented by Eric Fischer, 10:00 am.
- Getting to Heatmap: Spatial Interpolation Made Simple: Heatmaps are not just a way for simplifying points. When executed thoughtfully they can yield information not just about spatial clusters, but also patterns and missing values. Methods for turning points into continuous surfaces include: point density, line density, spline, inverse distance weighting, kriging. This session will walk through the advantages and disadvantages of a each, and their underlying assumptions and biases. Expect to leave with an understanding of these techniques and how to apply them. Presented by Stephanie May, 11:00 am.
Space is limited to 24 participants. This workshop is an auxiliary event to the State of the Map US conference taking place at the same venue over the weekend.
