Exploring: Remote Sensing
The surface of the Earth is changing rapidly, at local, regional, national, even global scales, with significant repercussions for people, the economy, and the environment. Remote sensing satellites and aircraft monitor the Earth providing information that is broad, precise, impartial, and easily available. In addition to operating the Landsat satellites, USGS provides the Nation's portal to the largest archive of remotely sensed land data in the world, supplying continuous access to current and historical land images worldwide.
Using remote sensing to quantify ecosystem site potential community structure and deviation in the Great Basin, United States
The semi-arid Great Basin region in the Northwest U.S. is impacted by a suite of change agents including fire, grazing, and climate variability to which native vegetation can have low resilience and resistance. Assessing ecosystem condition in relation to these change agents is difficult due to a lack of a consistent and objective Site Potential (...
