Southwest Florida Water Management District Land Use and Cover 2017

Southwest Florida Water Management District 20190807 Southwest Florida Water Management District Land Use and Cover 2017 vector digital data https://data-swfwmd.opendata.arcgis.com/datasets/land-use-land-cover-2017 The 2017 land use land cover features categorized according to the Florida Land Use and Cover Classification System (FLUCCS) for the Southwest Florida Water Management District. Update from a 2011 land use land cover dataset using the Florida Land Use, Cover, and Forms Classification System (FLUCCS). Heads up digitized vector edits were made by the photointerpretation of landuse change between 2011 and 2017 orthoimagery. Changes were delineated and updated to the most relevant level 2 (LEV2) when a clear change greater than 1/2 to 2 acres (depending on landuse class rule) was present between 2011 and 2017. Errors of omission and commission present in the 2011 data were not addressed explicitly. This service is for the Open Data Download application for the Southwest Florida Water Management District. This is an update to the FGDL Layer LU_SWFWMD_2011. The 2017 land use land cover features. This service is for the Open Data Download application for the Southwest Florida Water Management District.

In order to assure the accuracy specifications for the project are met, a stratified random sampling method was used to determine estimated error rates. The stratification is designed to evaluate the accuracy of change detection as well as the accuracy of the classification when change is identified. The stratification is outlined as follows: 1) 500 points within change, 50% of sample, 2) 300 points in areas near change (235 foot buffer outside change), 30% of sample, and 3) 200 points in areas without change, 20% of sample. If the accuracy assessment was within 85% of the derived change dataset it passed the defined quality standards. There are no significant omissions. Errors within the original 2011 FLUCCS classification were assumed the responsibility of SWFWMD. Visual inspection of the 2011 linework over the 6-inch digital aerial photographs, at a scale of 1:7,000, was used to verify the positional placement of the linework. Photo interpretation, editing and QC (quality control) were performed directly on screen. Data is estimated to be compliant with the National Map Accuracy Standards for 1:12,000, estimated +/- 33.3 feet. The goal of this project was to update the existing 2011 land use and land cover data layer using 2017 6-inch digital aerial photographs that meet or exceed National Map Accuracy Standards for 1:12,000. 20170101 Ortho2017 None 20170101 ground condition Ortho2017 2017 Imagery imagery used to detect changes in land use between 2011 and 2017 20190807 Land_Use_Land_Cover_2017 None 20170101 ground condition Land_Use_Land_Cover_2017 Final Land Use Land Cover Change Feature Class for 2017. 20190807 cRaster None 20190807 publication date cRaster Change raster produced from automated process that determines land cover change from aerial photography between 2011 and 2017. 20120316 LULC2011 None 20110101 ground condition LULC2011 Initial Land Use Land Cover feature class used to determine changes between 2011 and 2017. 20110101 Ortho2011 None 20110101 ground condition Ortho2011 2011 Imagery imagery used to detect changes in land use between 2011 and 2017 The change raster was developed using eCognition object classification.
