Overview

These data were collected by Leading Edge Geomatics using a Leica Chiroptera II Bathymetric & Topographic Sensor. The data were acquired from October 22, 2018 through May 31, 2019. The data include topobathy data in LAS 1.4 format classified as created, unclassified (1); ground (2); noise (low or high) (7); bathymetric bottom (40); water surface (41); derived water surface (42); submerged object (43); IHO S-57 object (44); no bathymetric bottom found (45); and bathymetric bottom temporal changes (46) in accordance with project specifications. The project consists of approximately 942 square miles of data along the Gulf shore of Texas from Galveston to Corpus Christi. This full project delivery consists of 3813 1000 m x 1000 m lidar tiles in five blocks: Block 01 delivery consists of 322 1000 m x 1000 m lidar tiles. Block 02 delivery consists of 871 1000 m x 1000 m lidar tiles. Block 03 delivery consists of 789 1000 m x 1000 m lidar tiles. Block 04 delivery consists of 557 1000 m x 1000 m lidar tiles. Block 05 delivery consists of 1274 1000 m x 1000 m lidar tiles. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
