Corners established as part of the original government survey are the basis for legal descriptions of real property in Florida. The section corners identified as Verified = “NO” were initially added from a spreadsheet containing State Plane X/Y coordinates transferred from certified corner records by Lee County Property Appraiser. Coordinates were converted from NAD27 to NAD83 using CORPSCON as needed. The verified section corners (Verified = “YES”) are corners that were field verified by a certified surveyor contracted by Lee County. BLM is the Bureau of Land Management ID used to locate certified corner records on LABINS website. Example : T45SR24E500300 is the SW corner of section 23-T45S-R24E. The last 6 digits can be found on the BLM identifier grid/chart on LABINS website, http://www.labins.org/survey_data/landrecords/landrecords.cfmPointNumber is an internal number that was assigned by surveyorX_COORD and Y_COORD are State Plane Coordinates, Florida West, feet LABINSlink hyperlinks to the LABINS recordRecoverySheet is a hyperlink to the Lee County recovery sheet N27 and E27 are the northing and easting, NAD27 datumN83 and E83 are the NAD27 coordinates converted to NAD83

This data layer is St. Johns River Water Management District's (SJRWMD) modification of Florida's Land Boundary Information System's (LABINS.org) Public Lands Survey System (PLSS). It contains added attribute data including Spanish land grant names where applicable. As of 23Jan2012, sections within the Suwannee River Water Management District are represented spatially and tabularly by a layer from SRWMD.

This data set contains polygons representing a section-township-range grid developed from combination of LABINS grid, certified section corners and existing information. While an improvement over existing Section grid data, these data are considered non-final.
