|2006 Texas Water Development Board (TWDB) Lidar: Galveston County
|Using a LH Systems ALS50 Light Detection And Ranging (LiDAR) system, flight lines
of standard density (1.4 meter ground sample distance) data were collected over areas
in Galveston County, TX (approximately 400 square miles). Multiple returns were recorded
for each laser pulse along with an intensity value for each return. The data acquisition
occurred in missions during the fall of 2006. The data was collected by Sanborn Mapping
Company, Inc. for the Texas Water Development Board (TWDB) and the Federal Emergency
Management Agency (FEMA).
