 "description": "Land cover and land use in the St. Johns River Water Management District based on 2013-2016 digital orthophotography. This layer is a copy of the 2009 lulc dataset, with updates based on conditions in the 2013-2016 orthophotography. The previous Photointerpretation Key was also revised and updated for this project.Source imagery is county imagery flown primarily by FDOT, at varying dates . The 2014 map used the below imagery:Year Flight Season Counties2013 (Dec 2012 \u2013Mar 2013) Duval2014 (Dec 2013 \u2013Mar 2014) Alachua, Baker, Bradford, Clay, Flagler, Lake, Marion, Nassau,Osceola, Polk, Putnam, St. John\u2019s2015 (Dec 2014 \u2013Mar 2015) Brevard, Indian River, Okeechobee, Seminole, Volusia2016 (Dec 2015 \u2013Mar 2016) OrangeNOTE: Mapping convention made for Marion/Alachua counties. Imagery Dates: Alachua - December 2013 - January 2014; Marion - March 2014 -April 2014. Implications for land cover mapping: We experienced a wetter than average winter, and significant rain fell between Alachua and Marion flight dates. Orange Lake looked very different in areas where the two county imagery datasets overlapped (higher water levels in Marion imagery). We decided on the following mapping convention: always map according to the Marion imagery where it exists.The 2014 data is mapped to the extent of the previous update in 2009 as far as available imagery allowed. There is data to the east of Nassau County (outside our District and Water Basin boundaries) where no imagery was available. The 2014 data extends beyond its previous limit in a few small areas to fulfill an internal staff request.It continues the historical practice of mapping the portion of the Ocklawaha River Basin in Polk County that was transferred to the Southwest Florida Water Management District.NOTE: June 2018 Changes to Dataset:The 2014 dataset was modified in June 2018 based on results from an Accuracy Assessment, These edits changed net acreage counts for some classes as follows:ACREAGE INCREASES: Class 3300 +2.77 ac / Class 4200 +5.12 ac / Class 5200 +7,254.66 ac / Class 5300 +174,082.38 ac / Class 8350 +122.27 acACREAGE DECREASES: Class 1750 -16.64 ac / Class 2110 -100.00 ac / Class 4110 -3.63 ac / Class 4210 -2.00 ac / Class 5100 -181,337.04 / Class 7400 -7.90 ac",
