Alex and I will be at this weekend’s Reinvent Green Hackathon in New York City to help attendees make maps and data visualizations. In preparation we have rendered several of the suggested datasets from the New York City open data portal.
These layers may be useful out of the box for your project, or you may wish to tweak them and combine them with other datasources. The TileMill projects we used to create these layers are all available for download on GitHub. To get started working with these layers download TileMill and head over to the help section. If you’re simply in need of a fast street level map, take a look at MapBox Streets. NYC City-wide GIS has also pulled together some useful maps and suggestions that I recommend checking out.
Alex and I will be available for questions and hands on help during the hackathon’s “office hours” on Saturday morning and throughout the weekend. If you have any questions before then, you can find me on Twitter at @ian_villeda.
