What is Public Laboratory?"Public Lab is a community where you can learn how to investigate environmental concerns. Using inexpensive DIY techniques, we seek to change how people see the world in environmental, social, and political terms"
Why Balloons and Kites?"These tools are being developed to provide a low cost, easy to use, and safe methods for making maps and aerial images. Over the last two years, we’ve built a global community of mappers who are engaged in discussion around the development and use of this tool and others.
Normally aerial maps are made from satellites and airplanes. The balloon and kite ground-based approach introduces an on-demand capability where events or environmental conditions are mapped at a specific moment in time. Our community is particularly interested in applying this to civic and environmental issues."
