Texas Hurricane Harvey LiDAR Project

This page includes a summary of the Texas Hurricane Harvey LiDAR Acquisition project, completed for USGS. To view or download LiDAR data in Equator now, click the link below.

The Texas Hurricane LiDAR Project 

LiDAR in Texas was acquired between January 4, 2019 and February 20, 2019 in 69 separate collections.  The project was carried out for the USGS.  In total, 14,512 square miles were surveyed.

LiDAR Data Collection

Fugro was hired to carry out the airborne LiDAR survey. They used a Leica ALS80 sensor for data collection. The data was collected with an aggregate nominal pulse spacing (ANPS) of 0.71 meters. Lidar data was collected in accordance with U.S. Geological Survey National Geospatial Program Lidar Base Specification Version 1.3.
