"The Public Laboratory for Open Technology and Science (Public Lab) is a community which develops and applies open-source tools to environmental exploration and investigation. By democratizing inexpensive and accessible ?Do-It-Yourself? techniques, Public Lab creates a collaborative network of practitioners who actively re-imagine the human relationship with the environment.
The core Public Lab program is focused on ?civic science? in which we research open source hardware and software tools and methods to generate knowledge and share data about community environmental health. Our goal is to increase the ability of underserved communities to identify, redress, remediate, and create awareness and accountability around environmental concerns. Public Lab achieves this by providing online and offline training, education and support, and by focusing on locally-relevant outcomes that emphasize human capacity and understanding."

"Using inexpensive DIY techniques, we seek to change how people see the world in environmental, social, and political terms. We are activists, educators, technologists, and community organizers interested in new ways to promote action, intervention, and awareness through a participatory research model.
This community began as the Grassroots Mapping project, an effort to produce Do-It-Yourself satellite imagery with balloons and kites, most notably during the 2010 BP oil spill. We are now broadening our scope to explore new inexpensive and community-led means to measure and explore environmental and social issues."

""Everybody needs maps, and being able to make your own map is important," Stewart Long, director of geography and data for GonzoEarth mapping services, told me before I had set out on this mission. Long has been doing aerial camera cartography for years, and he's one of the cofounders of the Public Laboratory for Open Technology and Science (Public Lab). It's a nonprofit organization that develops open source, do-it-yourself science tools—tools that have been embraced by environmental scientists, students, and activists.
Public Lab publishes a collection of resources for DIY aerial photography and mapping, as well as instructions on how to create other low-cost tools for environmental science. The organization sells pre-packaged kits through its Web store to help kickstart would-be aerial cartographers in getting their balloon- or kite-based sensor platforms into the skies. A kite from one of those kits was precisely what I was hauling out of Baltimore's shipping channel that November afternoon.
The importance of being able to create your own maps may not be immediately obvious to most people. Google, Apple, Bing, Garmin, and others have made turn-by-turn directions and bird's-eye views into a commodity. But the issue of who owns the skies above us and the images of the Earth we travel is one charged with increasing political baggage—especially as we face a future with skies filled with persistently watching drones mapping the movements of everyone below.
Using commercial maps carries a price tag—whether it's an actual dollar cost or the cost of having what we can see about the world filtered through a government's or company's point of view. Google and Bing have turned satellite and aerial imagery into a commercial geospatial information service that can transform where you are into an advertising platform. Local governments use aerial mapping to check for building code violations and assess property taxes. And increasingly, national governments are "mapping" in a different way, keeping a steady eye on the world below to track the movements of groups and individuals.
But in the hands of citizens, mapping can be a powerful tool as well. It can help us understand what's happening in the environment around us. Mapping is a journalistic tool and a tool of public accountability. With cheap, off-the-shelf components, individuals can create aerial maps for everything from documenting disasters to locating the sources of environmental pollution.
Public Lab's mission was born out of the necessity for such imagery. Starting in the summer of 2010, Long and others affiliated with Grassroots Mapping, a precursor effort to Public Lab, put together kits to help volunteers map the environmental impact of the BP Deepwater Horizon oil spill on the Gulf Coast. "Since 2010, we've mapped over 100 miles of shoreline in the Gulf region," he told me.
Since that effort, other scientists and environmental groups have adopted these techniques of DIY aerial mapping to collect a wide range of data. For example, one of Public Lab's efforts to create low-cost near-infrared digital photography for citizen scientists is giving scientists and farmers what amounts to a poor man's Landsat—a way to monitor vegetation health.
Even NASA has adopted some of the DIY techniques used by Public Lab for its own aerial mapping efforts. At a drone conference this past summer, an engineer from NASA's Goddard Space Flight Center told me that his team was using kites towed behind boats to do coastal mapping. The attraction is easy to explain: kites are relatively cheap, and they can fly over areas where even government drones can't yet fly. And while there are public sources of terrestrial imagery from satellites (such as NASA's MODIS data), their image resolution is limited—plus, satellites can't take pictures under the clouds.
Most commercially available high-resolution satellite and aerial imagery can be expensive to license. And few individuals or small organizations can afford to hire a plane to fly a photographic mission, let alone build their own spy satellite. Even if you have the resources to buy geospatial data from a commercial provider or put your own airplanes or satellites up to collect it, there's still one compelling reason to use the up-close and personal approach of DIY mapping—timing. DIY aerial photography allows for the collection of images on a schedule dictated by events, not by when a satellite will pass over on a clear day or when a plane can be scheduled.
Drones have shifted the economics of aerial imagery a bit, but only for those who are allowed to fly them. While the Federal Aviation Administration figures out how to get its act together on drones and allowing them to fly—probably no sooner than 2015—DIY aerial mappers don't face those kinds of restrictions. And balloons and kites have the advantage of being able to go just about anywhere on Earth, or at least anywhere that's not restricted airspace, without any runway requirements.
"UAVs are highly regulated, but these are systems you can use today, fly and start making maps, reusing materials you already have access to," Long told me as I was preparing to begin my own DIY mapping odyssey. "They're easy to use, and you can easily train others to use them."
With a regular point-and-shoot camera, the Public Lab design can be used to gather gigabytes of relatively high-resolution images that can be stitched together into a massively high-resolution image of the surface below. But add a smartphone and you get a lot more. Time-lapse photography and GPS location apps combined with a phone's cellular data connection can turn a balloon or kite into a real-time surveillance platform for the masses."
