DS-777 Annual Model-Forecasted Land-Use/Land-Cover Rasters from 2009 to 2050 for the A2 Climate Scenario for the High Plains Aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Estimates of area and aerial extent of land-use categories are an essential component for computing the water budget of the High Plains aquifer. These raster land-use land class data represent yearly simulated future land use for the High Plains from 2009 to 2050 These data were developed using the FOREcasting SCEnarios (FORE-SCE) of future land cover model (Sohl and others, 2007; Sohl and Sayler 2008) for two (A2 and B2) of the four Intergovernmental [...]

本数据集发布于2016年10月1日美国地质调查局（United States Geological Survey, USGS）科学数据审核、批准与发布政策生效日期之前，该政策详见USGS《勘测手册第502.8章：基础科学实践：科学数据发布的审核与批准》。土地利用类型的面积与空间分布范围估算，是计算高平原含水层（High Plains Aquifer）水收支的核心组成部分。本次提供的栅格（raster）土地利用类型数据，为2009年至2050年高平原区域逐年模拟的未来土地利用情景。本数据集基于未来土地覆盖情景预测模型（FOREcasting SCEnarios, FORE-SCE，Sohl等，2007；Sohl与Sayler，2008）生成，针对四类[……]中的A2与B2两种情景展开。
