Detailed Description

Continuous Global Positioning System (CGPS) Station P303 in Los Banos, CA. 
A CGPS station continuously measures the three-dimensional (3D) position of a point on, or more specifically, near the earth's surface. For this study, scientists are primarily interested in vertical movement (subsidence and uplift), but horizontal movement can be obtained with CGPS and can also be informative for subsidence studies.  CGPS stations are used to monitor subisdence in California's Central Valley.
