This video describes how to use the SAC conversion spreadsheet to convert data from a conventional level in angles and distances (polar coordinates) to Cartesian coordinates (northings and eastings). 
 

USGS Hydrologist, Krishangi Groover, lays wire in preparation for geophysical data collection at the U.S. Army's Fort Irwin National Training Center in California.  The metal bits on this wire connect to metal stakes (one can be seen in the foreground), which allows for the transmission of electricity into the ground to measure sediment properties.  This geophysical data

Vegetation grows abundantly on a once-flooded region of the Santa Ynez River. Located 5 ft adjacent from this picture is the actual flowing region of the stream. It is impressive to see the abrupt change in vegetation near stream environments.  Golden grasses, brick red brush, blue sky, and rocks coated white from sun-dried/sun-bleached algae where water used to sustain

The California Aqueduct flowing near Huron, CA in the San Joaquin Valley.  This spot is near one of several USGS land subsidence monitoring stations in the San Joaquin Valley. Land subsidence has reduced the conveyance capacity of the Aqueduct and other water

The USGS maintains and monitors hundreds of streamgages across California, as well as across the Nation. Nearly all data collected by the USGS is made public and most in near real-time. Cities can use the data for flood mitigation and water supply. Understanding the amount of water flowing in the watersheds all across America is essential to everything we do, as water is
