2010 U.S. Geological Survey (USGS) Topographic LiDAR: San Francisco Bay, California

Metadata Updated: February 7, 2018

The primary purpose of this project was to develop a consistent and accurate surface elevation dataset derived from high-accuracy Light Detection and Ranging (LiDAR) technology for the USGS San Francisco Coastal LiDAR project area. The LiDAR data were processed to a bare-earth digital terrain model (DTM). Detailed breaklines and bare-earth DEMs were produced for the project area. Data was formatted according to tiles with each tile covering an area of 1500 m by 1500 m. A total of 712 tiles were produced for the project encompassing an area of approximately 610 sq. miles. This metadata relates to LAS that were classified in the following classes: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 7= Noise Class 9 = Water Class 10= Ignored Ground (due to proximity to breakline)

Access Constraints Use Constraints: Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. These data depict the heights at the time of the survey and are only accurate for that time., Access Constraints: None
