Happy 50th Anniversary to EROS (Earth Resources Observation and Science) Center. #MapMonday

“Since 1972, EROS has worked to map, monitor, and analyze land change across our nation and around the world” (EROS website). This USGS facility is located by Sioux Falls, SD, and is a treasure-trove of satellite images and aerial photographs.”

Documents and photographs concerning the early history of EROS and ERTS (Earth Resources Technology Satellite) can be found in the James G. Abourezk papers in the Archives and Special Collections.

Also, a couple of the archival collections have large aerial photographs that I believe came from EROS. I particularly like the 38” x 38” black and white photograph of the USD campus in 1999.
