Urban Growth: Las Vegas This Landsat image shows Las Vegas in 1973 (population 358,400). Purple areas represent roads and other urban infrastructure. By 2000, Las Vegas (population 1,563,280) had sprawled in almost all directions, especially in the northeast and southeast.

Marshall, C.H. Jr., R.A. Pielke Sr., and L.T. Steyaert, 2003. Crop freezes and land-use change in Florida. Nature, 426, 29-30. 1900-era Land Cover 1993 Land Cover Model difference in minimum temperature Model difference in duration of freeze temperatures Areas where wetlands were converted to cropland had colder minimum temperatures and longer freezing periods. Wetlands once held heat from the day, often keeping area temperatures above freezing throughout the night. Goal: Understand past, present, and future environmental consequences of land change to support better management of their effect on people, environment, economy, and resources

The U.S. must commit to continue the collection of moderate-resolution land imagery. The U.S. should establish and maintain a core operational capability to collect moderate-resolution land imagery through the procurement and launch of a series of U.S.-owned satellites (Landsat 9 and beyond). The U.S. should establish the National Land Imaging Program, hosted and managed by the Department of the Interior, to meet U.S. civil land imaging needs.
