Daniel G. Sorenson
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.
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. I have also been a part of the accuracy assessment of the NLCD product.
I am the content manager for the Western Geographic Science Center.
