| 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 San Patricio County, TX (approximately 705 square miles). Multiple returns were
recorded for each laser pulse along with an intensity value for each return. The data
acquisition occurred in 6 missions between July 10, 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).
