GeoPlan relied on the integrity of the attribute information within the original data. LCCODE and LUCODE values were screened to ensure that they belonged to the set of legal FLUCCS values for this data layer, as defined in the SJRWMD 2004 Photointerpretation Key.

The source imagery was obtained from December 2003 to March 2004 and used to produce orthophotos with a one meter ground resolution. Imagery was acquired at 0.62 meter ground sample distance (GSD) resolution. Flight height maintained during mission was 20,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was captured with 20% sidelap between all adjacent flight lines. The SJRWMD project area was divided into 5 flight blocks due to necessary base station and flight line length requirements. The imagery was obtained and processed by all digital means beginning with data acquisition using a Leica ADS40 Digital Airborne Sensor. The orthophotos are available in GeoTIFF form. The projected coordinate system is UTM zone 17 N, NAD 83 HARN, GRS 80, Units Meters. Differences between the District FLUCCS and the statewide FDOT FLUCCS. Every effort is made to keep the District's classification system consistent with the statewide system and those of adjacent districts (SF, SWF, and SR). The classes in the District system use the same names, code numbers and descriptions as the FDOT FLUCCS, in almost all cases. Definitions have been modified or expanded to meet the District's requirements, or to provide necessary clarification to PI's and users. Significant departures from the FDOT FLUCCS are noted in the PI Key pages and in the attached table fluccs_all_layers. One significant difference between the District and Statewide FLUCCS is with the 3000 category - formerly Rangeland. This level 1 class has been re-named to Upland Non-forested, to better conform to actual mapping practices and landscape conditions. The District realized that many of the herbaceous and shrub areas mapped as 3000s do not meet the FDOT definition of rangeland - they tend rather to be open non-forested areas in urban or rural contexts other than range. A detailed explanation of this change is found at the 3000 PI Key page. A minor change was made to the 4300 class, changing from 'Upland Hardwood Forests, Continued' to 'Upland Mixed Forest'. However none of the active codes used in these categories are changed from the FDOT version. This change creates a more logical system for the District's purposes. Users should also note that the definition of 'Forested' vs. 'Non-forested' has been changed. The District system requires 25% rather than 10% canopy closure to be considered Forested.

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.

This layer is based upon 2004 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.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:

The following steps were conducted onsite by staff of Kyra InfoTech, Inc, to create the 2004 layer. See Statement of work and purchase order specifications (District Purchase order # PO038177) for further details. 1. For each DOQQ, the photointerpreters will create a 2004 layer by modifying a copy of the 2000 layer according to thematic and boundary changes indicated by the 2004 DOQQs. 2. All mapping shall be from screen digitizing color-infrared (CIR) 3.75' Digital Orthophoto Quarter Quadrangles (DOQQ), in ArcGIS 9, with an adjacent digital stereo capable imagery and software for inspecting the digital imagery. 3. All mapping shall be conducted while consulting the ancillary data. 4. All classification will be in keeping with specifications listed in the PI Key. If the PI Key is unclear or incorrect, or if the photointerpreters have questions regarding appropriate classification, the internal District photointerpreter will make the decision. 5. The 2004 layer will have two land use classification items: LCCODE and LUCODE. LCCODE will be used for land cover, while LUCODE will be used for land use; item values will differ only when land use and land cover for any given polygon differ. Detailed guidelines for application of this dual coding scheme are discussed in the PI Key. The contract was initiated Sept. 2004, work began November 2004, and work Sept 2006. Adapting the use of Geodatabase for update and editing of data as well as technical issues with software and hardware slowed the project down in its early phases. Process Date: September 30, 2006 All phases were QA'ed by the SJRWMD photointerpretation specialist. Comments were sent to the photointerpreter(s) who then revised the data accordingly. Process Date: September 30, 2006 Spatial data was checked for topology errors against the following rules: No gaps between polygons No overlapping polygons A cluster tolerance of 0.05 meters was used. Where substantial overlaps or gaps existed, an SJRWMD photointerpretation specialist was consulted and the errors corrected. Process Date: October 2006 The Land Use/Land Cover code combinations were checked for all features against the modified FLUCCS code. Illegal code combinations were corrected. Process Date: October 2006 The landuse/land cover data in quarter quad areas around the periphery of the SJRWMD boundary were checked for completeness. If changes to the LULC data for the quarter quad were a result of changes to features shared by complete, neighboring quarter quad data, the features for the quarter quad in question were clipped and deleted. Process Date: October 2006 The GeoPlan Center downloaded the original St. John River Water Management District datasets (see below) from the following FTP site on May 21st, 2008. ftp://www.sjrwmd.com/disk6b/lcover_luse/luse2004/ lulc2004_alachua.zip lulc2004_baker.zip lulc2004_bradford.zip lulc2004_brevard.zip lulc2004_clay.zip lulc2004_columbia.zip lulc2004_desc.dbf lulc2004_duval.zip lulc2004_flagler.zip lulc2004_indian_river.zip lulc2004_lake.zip lulc2004_marion.zip lulc2004_nassau.zip lulc2004_okeechobee.zip lulc2004_orange.zip lulc2004_osceola.zip lulc2004_polk.zip lulc2004_putnam.zip lulc2004_seminole.zip lulc2004_st_johns.zip lulc2004_st_lucie.zip lulc2004_union.zip lulc2004_volusia.zip Each county was downloaded and unzipped. Next the counties were merged to create one district wide layer. Next the district wide layer was dissolved (single part) on both the LUCODE and LCCODE, 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 354563 to 333954 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 LCCODEs. 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 a table join was performed between the lulc2004_desc.dbf and the district-wide layer based on the CODE field in the lulc2004_desc.dbf, and the LUCODE field in the shapefile. Once joined the layer was exported. in order to permanently append the lulc2004_desc.dbf table information. Next the records in the attribute table were UPPERCASED.
