EJSCREEN: Environmental Justice Screening and Mapping Tool | US EPA

220px-Environmental_Protection_Agency_logoIn order to better meet the Agency’s responsibilities related to the protection of public health and the environment, EPA has developed a new environmental justice (EJ) mapping and screening tool called EJSCREEN. It is based on nationally consistent data and an approach that combines environmental and demographic indicators in maps and reports.EJSCREEN users choose a geographic area; the tool then provides demographic and environmental information for that area. All of the EJSCREEN indicators are publicly-available data. EJSCREEN simply provides a way to display this information and includes a method for combining environmental and demographic indicators into EJ indexes.

USGS mashing up data to create new views of country

 The U.S. Geological Survey isn’t walking the mountains and snowy terrain of Alaska to update its 50-year-old maps. 

Nope, USGS is taking advantage of new technology to paint a picture of the nation’s biggest state like never before. 

Kevin Gallagher, the associate director for core science systems at USGS, said over the last 18 months the Department of Interior bureau has been working with a dozen or so other agencies, states and non-profits to create a strategy to fly the state using Interferometrics synthetic aperture radar (InSAR) to get high resolution elevation pictures as well as updating hydrography data and to acquire transportation data. 

“We just now are starting to release digital topographic series for Alaska, so it’s really exciting. We’ve got about 40 percent of state covered with the critical data we need,” he said. “We’ve got it phased out to be a three-to-four year project depending on resources. Some of the maps that are coming out now are a resolution of data like Alaska has never seen, and it will make dramatic improvements to the way we look at the state, the way we manage the state and the decisions we make over the next few years.”
