Grassroots Mapping: How You Can Create Aerial Cartography for Under $100, and Use It to Do Good

by Ben Jervey

March 9, 2011

Of the oil spill work, the Grassroots Mapping team explained:

We're helping citizens to use balloons, kites, and other simple and inexpensive tools to produce their own aerial imagery of the spill… documentation that will be essential for environmental and legal use in coming yeas.We believe in complete open access to spill imagery and are releasing all imagery into the public domain.

I particularly this elementary piece of advice: the rule of thumb is, less than 10 miles per hour of wind is good balloon weather, more than 10 miles per hour of wind is good kite weather. For a look as some citizen mappers working in the notoriously polluted Gowanus Canal area of Brooklyn, OnEarth has a great story and slide show. We'll put together our own slide show soon of the best images from this nascent, crucial movement.
