Nearly 40 years of USGS satellite imagery shows dramatic changes in the surface features of the Earth, says Ron Beck of the U.S. Geological Survey, who will give a free talk on the topic at 7 p.m. Thursday, July 29, on the USGS campus in Menlo Park.
The talk, "Looking Down on Our Planet," will deal with such topics as changing patterns of land use as seen in urban growth, clear cutting of Amazon forests, and surface mining.
Landsat imagery monitors the environmental impact of human disasters such as the Deepwater Horizon oil spill.
The program will be held in Conference Room A, Building 3, on the USGS campus at 345 Middlefield Road in Menlo Park.
