    dct:description "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)" ;
