2006 Texas Water Development Board (TWDB) Lidar: Northern Cameron and Willacy Counties

Using a LH Systems ALS50 Light Detection And Ranging (LiDAR) system, standard density (1.4 meter ground sample distance) data were collected over areas in Northern Cameron and Willacy Counties, TX (approximately 1021 square miles). Multiple returns were recorded for each laser pulse along with an intensity value for each return. The data are bare earth classified. The data acquisition occurred in 36 missions between December 14, 2005 and February 23, 2006. The data was collected by Sanborn Mapping Company, Inc. for the Texas Water Development Board (TWDB) and the Federal Emergency Management Agency (FEMA).
