Following the Cartography and GIS Dorkshop I gave last weekend I was invited to give a 3 hour open-source Geo demonstration with QGIS, Tile Mill, and MapBox at a Trans-Disciplinary Design class taught by Mathan Rathinam, here at Parsons.  The class is dealing with issues relating to environmental hazards and disaster resilience in NYC, so to make the connection between the class and the Geo tools we used some spatial data from NYC Open Data. We pulled in two datasets; one for hurricane evacuation zones and another for evacuation centers. The zones have a classification from 1 – 6, with 1 being the highest at risk areas prone to flooding and 6 being the least. In the class I demonstrated how to load and style this data in TileMill using a sequential color scheme as demonstrated on Cynthia Brewer’s Color Brewer Cartography guideIn the map above I’ve refined the design a little further, using some advanced labeling with SVG icons from TileMill’s open-source Maki icon repository. I also used the MapBox API to add a “Find My Location” button that will drop an icon based on the user’s IP address.  Additionally, clicking on an icon will reveal it’s full address in the upper right hand corner.  I enjoyed teaching the material to the class and look forward to giving more workshops and demos, hopefully bringing in some guest speakers as well. Thanks again to Mathan and his class for having me, it was a pleasure.
