County approves contract for 3-D topographic mapping, surface modeling

The San Diego County Board of Supervisors voted 5-0 July 20 to approve a funding agreement between the county and the U.S. Geological Survey (USGS) for three-dimensional topographic mapping and surface modeling of San Diego County.

USGS will use light detection and ranging (lidar) remote sensing technology to map the portions of San Diego County for which data does not currently exist. The high-resolution elevation data will have applications for studies focusing on infrastructure or the environment.
