We spent yersterday’s Earth Day at our offices in NYC trying to do balloon mapping, a nice way to end an intense EcoHackNYC weekend. It is the second time we co-organized this (un)conference. Last fall we gathered at NYU and this time we met at Parsons.
The event started Friday with a series of 5-minute ignite talks. On Saturday, we divided in small groups and worked on solutions. Here is a sample of some of our favorite geospatial projects.
A five-team group, including three from Vizzuality, worked with a big and interesting dataset of 12 million endangered species trades, to create an interactive visualization called the Species Sphere. All data is fetched from CartoDB and visualized using d3.js. Amazing work done in just 8 hours!
Another group worked on a simple map interface to communicate local demand for community-supported agriculture (CSA). The project is built on Heroku for hosting, MapBox for map tiles, Leaflet for the mapping interface, and jQuery with CartoDB for all the analysis.

This time we also expanded the meeting beyond data and code and we teamed up with The Public Laboratory to add a hardware-hacking to the event. The Public Laboratory has developed a balloon mapping kit that enables you to collect your own aerial photos from up to 1000 ft. Using the open source MapKnitter web-based software, you can stitch the resulting images into a web-viewable map.
The Air Quality Egg team brought also their DYI sensor-box for real-time air column monitoring. It was customized and added to the balloon kit to gain additional capabilities. The system contains sensors to read NO2, CO, temperature, humidity, compass (to calculate wind direction), wind speed, dust (particulate matter), VOC’s, altitude, as well as O3, and streams the data in real-time via XBee to Pachube.com.
It was a great, brilliant event. We are looking forward to the next one!
