DS-777 Annual Model-Backcasted Land-Use/Land-Cover Rasters from 1949 to 2008 for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

Estimates of land use categories are an essential component for computing the water budget of the High Plains aquifer. These raster land-use data represent yearly estimated land use for the High Plains from 1949 to 2008. These data were developed using the FOREcasting SCEnarios of future land cover (FORE-SCE) model (Sohl and others, 2007) and then processed using a Geographic Information System (GIS). The GIS software used to process these data was Environmental Systems Research Institute (ESRI, Inc.) ArcGIS Desktop 9.3.1.

土地利用类别估算数据是高平原含水层（High Plains aquifer）水平衡计算的核心组成部分。本数据集包含的栅格土地利用数据，涵盖了1949年至2008年高平原地区逐年估算的土地利用状况。该数据集依托未来土地覆盖预测情景（FOREcasting SCEnarios of future land cover，缩写为FORE-SCE）模型（Sohl等，2007年）生成，并通过地理信息系统（Geographic Information System，缩写GIS）完成处理。本次数据处理所用的GIS软件为环境系统研究所（Environmental Systems Research Institute, Inc.，简称ESRI）的ArcGIS Desktop 9.3.1。
