Last week, we added a new example to our resource library: the Environmental Defense Fund's interactive mapping application of "dirty" heating oil in New York City on a building-by-building level. Because this is a great example of a nonprofit mapping application, I asked the EDF's Kira Marchenese to tell us a little bit more about the data sources, mapping tools, and processes that took place to create this project.
According to the Environmental Defense Fund, heating systems cause 50% more pollution in New York City than cars and trucks. EDF obtained data from the New York City Department of Environmental Protection in early 2009 showing which buildings in the city use the "dirty" No. 4 or No. 6 heating oil, as opposed to the relatively cleaner-burning No. 2 oil or natural gas. This Flash-based map, created from that data, shows a building-by-building status of heating oil in use, as well as pending applications for fuel changes. In addition, this map features an address search widget so that you can look for a specific building directly.
WaterGoodness is a new site allowing users to share and find water quality reports across the United States. The site combines water quality and pollution data from a variety of government sources with visitor reports of their local water quality.
By searching the US Environmental Protection Agency's database, GreenSpaceMap offers visitors the ability to locate environmental threats in their neighborhood or region. Locations like Superfund sites and brownfields are visible once you type in a starting address. This is also an entry in the Sunlight Labs Apps for America contest.
