The data release provides a detailed digital field-verified shapefile of irrigated agricultural land-use within Charlotte County, Florida and a table summarizing the results for the 2018 growing season (November 2017 through September 2018). The land-use shapefile and acreage table produced for this study will be compared to the Florida Statewide Agricultural Irrigation Demand (FSAID) Irrigated Lands Geodatabase (IGL), version V (The Balmoral Group, 2017) totals for Charlotte County, in an effort to help validate the irrigated crop acreages estimated in 2015 and to provide a better basis for the next set of estimates in 2020. Field-verified data on crop type, irrigated lands, and acreage summaries provide FDACS a more accurate basis for estimating current and future water demands. Details on the procedures and methodologies used for mapping and field verification in Charlotte County are the same as those used for Polk County, Florida, and can be found in Marella and others (2017).
