Towill Inc. collected LiDAR for over 3,500 square miles in York, Pickens, Anderson, and Oconee Counties in South Carolina. This metadata covers the LiDAR produced for York County. The nominal pulse spacing for this project was 1.4 meters. This project was collected with a sensor which collects waveform data and provides an intensity value for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to contract specifications: 1-Unclassified, 2-Ground, 7-Noise, 8-Model Key Points, 9-Water, 10-Ignored Ground due to breakline proximity. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the 677 tiles (5000 ft x 5000 ft) that cover the project area. York County was delivered as part of the Tricounty collection however, the lidar report for Tricounty states: "A report covering the York County deliverable was also created and submitted separately". This metadata pertains to York county only. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
