GIS shapefile and summary tables of the extent of irrigated agricultural land use for 11 counties fully or partially within the St. Johns River Water Management District Florida, 2022–23

A Geographic Information System shapefile and summary tables of the extent of irrigated agricultural land-use are provided for eleven counties fully or partially within the St. Johns River Water Management District (full-county extents of: Brevard, Clay, Duval, Flagler, Indian River, Nassau, Osceola, Putnam, Seminole, St. Johns, and Volusia counties). These files were compiled through a cooperative project between the U.S. Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated lands that were verified during field surveying that started in November 2022 and concluded in August 2023. Field data collected were crop type, irrigation system type, and primary water source used. A map image of the shapefile is also provided. Previously published estimates of irrigation acreage for years since 1987 are included in summary tables.

本数据集提供覆盖全部或部分位于圣约翰斯河水资源管理区（St. Johns River Water Management District）内的11个县的地理信息系统（Geographic Information System, GIS）形状文件（shapefile）与灌溉农业用地范围汇总表，涉及县份包括布雷瓦德（Brevard）、克莱（Clay）、杜瓦尔（Duval）、弗拉格勒（Flagler）、印第安河（Indian River）、拿骚（Nassau）、奥西奥拉（Osceola）、普特南（Putnam）、塞米诺尔（Seminole）、圣约翰斯（St. Johns）以及沃卢西亚（Volusia）县，且包含上述县份的全域范围数据。
本数据集由美国地质调查局（U.S. Geological Survey）与佛罗里达州农业与消费者服务部农业水政策办公室联合编制完成。其中形状文件收录了2022年11月启动、2023年8月结束的野外实地勘测验证的灌溉用地位置信息，采集的野外调查数据涵盖作物类型、灌溉系统类型及主要供水水源。数据集同时附带该形状文件对应的地图影像。
汇总表中收录了1987年以来历年已公开发布的灌溉面积估算数据。
