Pixel by Pixel: How the USGS, U.S. Forest Service Checked the Work of a Computerized Landsat Mapping Project

About a year ago, scientist Bruce Pengra sat at his desk with a conundrum.

As part of the team working on the reference dataset for the USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative’s land cover mapping project, Pengra was staring at a single speck of satellite data, a nondescript blotch of color representing a 30-meter plot of ground in Washington state....
