These data include the types and extent of irrigated crops as well as information concerning dry agriculture, wetlands, open water, and urban areas. The annual data published by the program includes a finalized WRLU geospatial information systems (GIS) dataset, geospatial maps, and this report. Once published, the data are used for various planning purposes including approximating cropland water use, evaluating irrigated land losses, conversion to urban lands, planning for new water development, estimating irrigated acreages, and developing water budgets.本数据集涵盖灌溉作物的类型与种植范围，同时包含旱作农业、湿地、开阔水域以及城市区域的相关信息。该项目每年发布的成果包含最终版WRLU地理信息系统（GIS）数据集、地理空间地图与本报告。数据发布后可应用于各类规划场景，具体包括估算农田用水量、评估灌溉用地流失情况、监测灌溉用地向城市用地的转化、规划新水源开发项目、测算灌溉面积以及制定水资源预算。
