Why Collaborative Development Works in a Proprietary World

by Jeffrey Warren

Public Laboratory is made up of a diverse group of contributors, some working from their homes or garages, some from their workplaces or even university labs. What brings us together is the idea that open-source, collaborative development can result in inexpensive and accessible environmental sensing. But to many, the way our community operates can be disorienting. We've approached these unique challenges in several ways. Most people are familiar with collaborative development of textual works, such as co-authorship, or even mass co-authorship in projects such as Wikipedia. Software development is textual as well, and such communities are made possible by carefully...

Taking Steps Toward DIY Spectrometry, So Citizens Can Test for Pollutants

by Jeffrey Warren
2011 Knight News Challenge Winner

Several Public Laboratory groups have emerged around the development of new tools for measuring contamination and quantifying ecologic issues. Among them is an informal spectrometry working group, which is attempting to create an inexpensive spectrometer. Such an instrument offers the possibility of detecting and even quantifying contaminants such as polycyclic aromatic hydrocarbons, or PAHs -- exactly the kind of toxic residue which has resulted from the BP oil spill, and identified in concentrations of up to 4.5 percent at the bottom of the Gowanus Canal in Brooklyn, N.Y. While this is an ambitious and even speculative project, the idea that...

Creating a Participatory, Open Source Map of an Entire Country

by Jeffrey Warren

For the past few weeks I've been working from Tbilisi, Georgia -- the other Georgia -- with a fascinating organization called OpenMapsCaucasus (OMC for short), which has been hard at work creating the first participatory, public domain road map of an entire country. Created by JumpStart International, and building on previous mapping work in the West Bank and Gaza, OMC employs dozens of GPS-wielding mappers who work in teams across Georgia to collect, process and publish map data. The OMC office in Tbilisi is abuzz with tech-savvy students, GIS wizards, and a fun-loving and coffee-fueled atmosphere. The sheer amount...

DIY Mappers Offer Remarkable Images of Gulf Coast Oil Spill

by Jeffrey Warren

Last week, as the mainstream press reported on the worsening environmental and economic crisis that is the British Petroleum spill in the Gulf Coast, I and a small group of DIY mappers flew down to New Orleans to coordinate a grassroots, citizen effort to map the spill. Instead of helicopters and satellites, we deployed a new generation of low-cost tools, including weather balloons and kites with cameras attached. Since arriving, we've managed to mobilize small teams of Gulf Coast residents. Thanks to the fishermen and charter boat captains whose livelihood is at stake, we've been able to get teams...

Helium Balloons with Digital Cameras Create Grassroots Maps

by Jeffrey Warren
2011 Knight News Challenge Winner

I'm getting ready for day five of a two-week workshop for high schoolers at Beaver Country Day School in a suburb of Boston. The subject is my project, Grassroots Mapping, which helps teach people -- often young people -- around the world how to be activist cartographers and how to make their own maps. There's a twist, however: Instead of just marking a Google Map, or walking around with a GPS tracker, we construct simple capsules to hold a cheap digital camera, and send the whole package up on a helium balloon or a kite. The images are then...
