The coding scheme is a modified Florida Land Use/Land Cover and Forms Classification System (FLUCCS). A detailed discussion of the coding scheme can be found in the SJRWMD 1995 Photointerpretation Key (PI Key). The PI Key lists each class used in the 1995 land use / land cover layer, along with a detailed description, keys to photointerpretation, a list of similar classes, special mapping conventions if they exist, a sample DOQ image, and a field picture. SJRWMD staff may access the PI Key through GISDOC (Data, Data Users Guides, 1995 Land Use / Land Cover). For those outside the SJRWMD, the PI Key has been added to the GIS export library on CD#6. The files can also be accessed with a web browser on the SJRWMD web site: www.sjrwmd.com. Follow the links to Data, Geographic Information Systems, Download GIS Data; then locate the 1995 Land Use / Land cover entry in the table, select the download link, and select the lu95_pi_key link. The file keylist.html is the master file from which users can link to all the land use codes. Following is a list of valid LUCODE and LUCODE2 values.

The data layer covers the entire area within the SJRWMD jurisdiction plus about two miles beyond the SJRWMD boundary. The photography for the DOQs upon which this layer is based was flown by the National Aerial Photography Program (NAPP) from Jan 1994 through Dec 1995 with the bulk of photos taken in 1994. See the item DOQ95_INFO in the attribute table of gislib.img_idx_doqs for specific photo dates. An online Data User Guide is available (GISDOC, Data, Data User Guides). It contains information about completed quality assurance efforts, known problems with the data layer, and plans to update and improve the data.

This data layer was developed to support many of the District's critical projects or programs, including Pollution Load Reduction Goal Development, Land Acquisition, Land Management, Water Supply Planning, Floodplain Management, and Surface and Ground Water Quality Monitoring. Wetlands identified in this layer should only be used for general reference, not for legal purposes or detailed analysis. Local determinations always require field inspection.

SJRWMD: This layer is based upon 1994/1995 digital orthophoto quarterquads. Digital orthophoto quadrangles and quarter-quadrangles must meet horizontal National Map Accuracy Standards (NMAS) at 1:24,000 scale and 1:12,000 scale, respectively. The NMAS specify that 90 percent of the well-defined points tested must fall within 40 feet (1/50 inch) at 1:24,000 scale and 33.3 feet (1/30 inch) at 1:12,000 scale. To create the data, the orthorectified images were displayed on a computer screen at varying scales of about 1:12,000 or less.

DATA LINEAGE SUMMARY:

This dataset was developed using an on-screen digitizing approach to capture land use/cover information. Orthorectified images (DOQ) converted from 1:40,000 scale color-infrared photography were displayed on a computer screen at a scale of approximately 1:12,000. This on-screen digitizing approach also utilized stereoscopes for viewing the source photography, together with ancillary information including soils, FEMA floodplains, land parcels, etc. to assist the photointerpretation efforts. Process Date: This data layer has been through an extensive review process collaborated by the GIS Division and the contractor, Geonex Inc., to correct major discrepancies using the National Wetland Inventory (NWI), SJRWMD wetland vegetation, and the 1990 land use/cover datasets. This review effort was focused especially on the categories of waters (5000's) and wetlands (6000's). Process Date: Enviromental Sciences Division staff conducted a review of coding in the east central Clay County area, with a focus on agricultural land uses. As a result, the LUCODEs for 14 polygons were changed, primarily from field crop (2150) to improved pasture (2110). See for GIS Division staff for details. Process Date: 20000307 Division of GIS staff revised LUCODE values for 1.8% of the total polygons, representing 2.9% of the total area: 1. Added an item REV to the attribute table identifying polygons that were revised. A value of A indicates an attribute change only (LUCODE or LUCODE2); no arcs were revised. 2. Submerged aquatic vegetation: Moved submerged aquatic vegetation codes (6450) to LUCODE2 and populated LUCODE with the appropriate waterbody code. 3. Indian River Lagoon basin: Changed estuaries miscoded river (5100) to estuary (5400). 4. Lakes and Reservoirs: Many lakes were coded as reservoirs, and some reservoirs were coded as lakes. These were revised appropriately. 5. Commercial and Services: Collapsed all 1400 level 3 codes other than 1460 and 1480 into 1400. 6. Extractive: Revised codes 1650-1670 to be consistent with FLUCCS and the rest of the state. 7. Fixed miscellaneous erroneously coded polygons. A complete and detailed listing of the changes is available upon request, as well as summary files listing the frequency and total area of each land use class before and after the revisions. Process Date: 20000801 Layer inserted into SDE and Metadata imported. Process Date: 20020219 The GeoPlan Center downloaded the original St. John River Water Management District datasets (see below) from the following FTP site on November 22nd, 2011. ftp://www.sjrwmd.com/disk6b/lcover_luse/luse1995/ lulc1995_alachua.zip lulc1995_baker.zip lulc1995_bradford.zip lulc1995_brevard.zip lulc1995_clay.zip lulc1995_columbia.zip lulc1995_desc.dbf lulc1995_duval.zip lulc1995_flagler.zip lulc1995_indian_river.zip lulc1995_lake.zip lulc1995_marion.zip lulc1995_nassau.zip lulc1995_okeechobee.zip lulc1995_orange.zip lulc1995_osceola.zip lulc1995_polk.zip lulc1995_putnam.zip lulc1995_seminole.zip lulc1995_st_johns.zip lulc1995_st_lucie.zip lulc1995_union.zip lulc1995_volusia.zip Each county was downloaded and unzipped. Next the counties were merged to create one district wide layer. The newly created district-wide dataset was originally in NAD_1983_HARN_UTM_Zone_17N projection The district-wide layer was reprojected to the FGDL Albers projection. Next the district wide layer was dissolved (single part) on the LUCODE, to remove the feature lines created at the county boundaries, this was done to create a more uniform district wide layer. The district wide feature count went from 272,609 to 265,949 features upon completion of the dissolve. PLEASE NOTE: A few of the polygons found on the interior of the counties were dissolved into adjoining polygons with the same LUCODE and LUCODE2. Next a summary was run on the original district wide LUCODEDESC, with a min on the LUCODE in order to create a crosswalk table called lulc1995_desc.dbf Next a table join was performed between the lulc1995_desc.dbf and the district-wide layer based on the LUCODE field in the lulc1995_desc.dbf, and the LUCODE field in the shapefile. Once joined the layer was exported. in order to permanently append the lulc1995_desc.dbf table information. Next the records in the attribute table were UPPERCASED.
