Daniel Sorenson has worked for the government for over 30 years. Currently I am a geographer working with the Western Geographic Science Center in Seattle, WA.
Annual National Landcover Database
The Annual National Land Cover Database (NLCD) has harnessed the full Landsat data record to provide timely, long-term, and detailed land surface change information. Annual NLCD uses an ensemble of classification and change algorithms to map, monitor, and synthesize the complexities of land use, cover, and condition change through time.
My primary interested and expertise is in using Landsat and other remotely sensed imagery in map creation and analyze spatial patterns. I am also the content manager for the Western Geographic Science Center.
I started my federal career with the Defense Mapping Agency (DMA) as a geographer in the Geographic Names Branch. I edited the names and legends of maps and charts plus translated the Germanic language maps into English.
As a cartographer with the National Oceanic and Atmospheric Administration (NOAA), I compiled nautical charts, working mainly in the Gulf of Mexico region of the United States.
When I joined the U.S. Geographic Survey (USGS), I started as an assistant supervisor for the Digital Orthophoto Quad (DOQ) program reviewing the completed DOQs. After transferring to Seattle, I have worked mainly on the Trends and National Land Cover Dataset (NLCD) projects, especially being a part of the accuracy assessment of the NLCD product. Currently my main project is working on the Annual National Land Cover Dataset (Annual NLCD).
