Water Related Land Use (1986 to 1992)

Water Related Land Use (1986 to 1992) consists entirely of data generated from the "Slide Transfer Method" and there is no irrigation type recorded in the attributes. This layer was combined from multiple basin layers to create the earliest state wide layer. When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated. The water-related land use program is an effort by the Utah Division of Water Resources to quantify the acreages in the state of various land use types, especially those which are irrigated. Prior to 2017, land use was completed for a single basin each year. The present method is able to utilize historical line-work, attributes, and remotely sensed data to estimate acreage changes for the entire state in a single year.1986至1992年水相关土地利用数据集的所有数据均通过「滑动转移法（Slide Transfer Method）」生成，其属性字段未记录灌溉类型相关信息。该图层由多个流域图层合并而成，为犹他州首个全州范围的土地利用图层。若需使用此类合并生成的年度全州范围图层的多个子图层，请务必进行数据校验，避免因该类图层的生成机制导致部分流域出现数据重复问题。本水相关土地利用项目由犹他州水资源局（Utah Division of Water Resources）主导实施，旨在量化统计犹他州各类土地利用类型（尤其是灌溉用地）的面积规模。2017年以前，该项目每年仅完成单个流域的土地利用统计工作；现行统计方法可依托历史矢量线划数据、属性信息与遥感数据，在单年度内完成全州范围的土地利用面积变化估算。
