Abstract
 Locating Turf in Las Vegas Valley Using Remote Sensing Techniques Track: Remote Sensing Imagery Author(s): Judith Brandt The Southern Nevada Water Authority (SNWA) was established in 1989 by the State of Nevada to secure future water resources of Southern Nevada communities, including the fast-growing city of Las Vegas. Part of the effort to do this involves conservation of water in this dry desert community. Nearly 70 percent of water consumed is "lost" due to outdoor use-primarily irrigation of turf (grass). High resolution (6 inch) color infrared aerial imagery was flown in June of 2006 over the Las Vegas metropolitan area and surrounding communities. SNWA used remote sensing analysis techniques and GIS to determine the amount and distribution of turf and other vegetation within the Las Vegas Valley. Vegetation indices and newer, "non-traditional" classification techniques were employed to accomplish the vegetation and turf data extraction. GIS and common geoprocessing tools were used to examine the relationships between vegetation layers and existing municipal data.
