2006 Texas Water Development Board (TWDB) Lidar: Calhoun County
Using a LH Systems ALS50 Light Detection And Ranging (LiDAR) system, 64 flight lines of standard density (1.4 meter ground sample distance) data were collected over areas in Calhoun County, TX (approximately 545 square miles). Multiple returns were recorded for each laser pulse along with an intensity value for each return. The data acquisition occurred in 7 missions between June 26, 2006 and June 28, 2006 and another collection between July 12, 2006 and July 15, 2006. The data was collected by Sanborn Mapping Company, Inc. for the Texas Water Development Board (TWDB) and the Federal Emergency Management Agency (FEMA).
