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 2000 Photointerpretation Key. The PI Key lists each class used in the 2004 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). See below for a discussion of the use of LUCODE vs. LCCODE. Following is a list of valid LCCODE and LUCODE values. * Codes marked with an asterisk are not used for classification and are listed only for clarification. 1000* URBAN AND BUILT UP 1100 Residential, Low Density - Less than 2 dwelling units per acre 1180 Residential, Rural - Less than or equal to 0.5 dwelling units per acre (one unit on 2 or more acres) 1190 Low density under construction 1200 Residential, Med.

LCCODE *** Each feature is required to have two attributes, one emphasizing land cover (LCCODE) and the second land use (LUCODE). In most cases, these two values are the same. They differ in a minority of cases where separate cover and use values are required in order to adequately describe the mapping unit. The result is a map with dual codes. The LCCODE attribute can be used (mapped, queried, etc.) alone for a land cover emphasis; LUCODE can be used alone for a land use emphasis; or both can be used together. Any polygon described by the following LUCODE values must be assigned a different LCCODE value: 1180 - Rural residential (2-5 acres per dwelling unit) 1650 - Reclaimed mining lands 1670 - Abandoned mining lands 1900 - Open land (urban) 1920 - Inactive land with street pattern but no structures (urban) 2120 - Unimproved pasture 2600 - Other open lands (rural) Any polygon described by the following LCCODE values must be assigned a different LUCODE value: 8340 - Wastewater treatment - but only for those areas associated with the facility other than the buildings / facility itself 8360 - Other treatment ponds (non-sewage). In this case, the LUCODE must be populated with the associated land use or purpose of the ponds, e.g. dairy (2520) or cattle feeding operation (2310). Polygons described by the following LUCODEs may at the discretion of the photointerpreter have differing values for LUCODE and LCCODE: 1700 - Institutional 1730 - Military 1750 - Governmental (Kennedy Space Center only) 1800 - Recreational 1850 - Parks and zoos 2240 - Abandoned tree crops 2310 - Cattle feeding operations 2320 - Poultry feeding operations 2500 - Specialty farms 2510 - Horse farms 2520 - Dairies 8350 - Solid waste disposal

SJRWMD: 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 2009 Photointerpretation Key. GeoPlan relied on the integrity of the attribute information within the original data.

A detailed Photointerpretation Key is available at X:\IR\Documentation\LULC\lu2009_PI_Key\keylist.html The source imagery was primarily flown from December 2008 to March 2009. There are exceptions: see the metadata for the 2009 orthophotos for more details. (to be filled in here later ...) Important note about wetlands: The primary reference wetland occurrence is the SJRWMD Wetland Vegetation layer, which is based on photography from the late 1980s. In editing the 2009 land use / land cover layer, the assumption is that if a feature was identified as a wetland in the Wetland Vegetation layer, it is still considered a wetland, even if the vegetation has been disturbed. Exceptions in developed areas can occur, where the wetland feature has been eradicated or drained, or if prolonged dry conditions appear to have irreversibly impacted the wetland. Changes to 2009 compared to previous layers: 1. In 2009, the use of the 3000 classes (Upland nonforested) is restricted to natural areas, and no longer applies to grassy or herbaceous areas in an urban context. 2. Changes to Rural Residential features (LUCODE = 1180) - In 2004, rural residential classes (LUCODE = 1180) were required to have a different land cover code. In 2009, this rule was changed to require dual coding only if the cover type is forested (4000s), shrub and brush land (3200), or mixed upland nonforested (3300). - If the land use is pasture (LUCODE = 2110 or 2120), then both the LUCODE and LCCODE values should be classed as pasture, not 1180, even if a home is present. - If it appears that the majority of the feature is actively mowed, then both the LUCODE and LCCODE values should be 1180. 3. Changes to Improved Pasture (2110) - In 2009, improved pastures (LUCODE = 2110) may have a different land cover code where wetlands occur within the pasture. In these cases, the LCCODE is usually Wet Prairie (6430). 4. Changes to Unimproved Pasture (2120) - In 2009, unimproved pastures (LUCODE = 2120) must have a different land cover code such as 3100, 3200, 3300 or a wetland class. This change was made based on user feedback. 5. Changes to residential under construction (LUCODE = 1190, 1290, and 1390) - The percent cutoff was changed to 50%, meaning that if the feature is more than 50% complete, it should be classed as the regular residential type, not "under construction". In previous years, the cutoff was 67%. This change was made based on user feedback. - We also allow for "under construction" codes to be used for even very low percentages of completion, at the discretion of the PI. These cases are relatively few, and used where property data shows parcel lots already laid out, and residential use appears very likely, even with no visible construction activity. 6. Surface water collection basins (8370) can be used as both a land use and land cover code. To maintain the new convention that Herbaceous upland nonforested (3100) be used in natural or non-urban settings, 3100 can no longer be used as a cover type in conjunction with 8370.

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 2009 digital orthophotos. Digital orthophotos must meet horizontal National Map Accuracy Standards (NMAS) at 1:12,000 scale. The NMAS specify that 90 percent of the well-defined points tested must fall within 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:

The following steps were conducted onsite by contingent staff to create the 2009 layer. 1. The photointerpreters will create a 2009 layer by modifying a copy of the 2004 layer according to thematic and boundary changes indicated by the 2009 orthophotography. 2. All mapping shall be from screen digitizing color-infrared digital orthophotos in ArcGIS 9.3. 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 2009 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. Work began October 2009, and is ongoing as of 5/11/2010. Process Date: Not complete All phases are QA'ed by the SJRWMD photointerpretation specialist. Comments are discussed with the photointerpreter(s) who then revise the data accordingly. Process Date: Not complete At the completion of each phase, spatial data is checked for topology errors against the following rules: No gaps between polygons No overlapping polygons A cluster tolerance of 0.05 meters is used. Where substantial overlaps or gaps exist, the photointerpreters correct the errors. Process Date: Not complete At the completion of each phase, all Land Use/Land Cover code combinations are checked. Illegal code combinations are corrected. Process Date: Not complete Over 300 multipart features were discovered and exploded using ArcMap 9.3. Process Date: 20100416 Final QC steps - Specific check#1: Removed the "STATUS" and "CHECK_PREVIOUS_YEARS" fields. Only 26580 records (out of 332619 total) had a value of "1" for the "STATUS" field - the rest of the records were NULL. This field was probably used by Dawn for her own checking purposes. Only 14 records (out of 332619 total) had the "CHECK_PREVIOUS_YEARS" field populated. Again, this was probably used at one time by Dawn or Marty for their own checking purposes. Process Date: October 6, 2011 Specific check #3: Dissolved on the fields: LCCODE, LUCODE, EDITOR, EDIT_DATE. Added Acres field and recalculated. Process Date: October 6, 2011 Specific check #4: Manually reviewed all polygons with ACRES value < 0.09. Total=900 polygons. Merged as appropriate after visual inspection. Acres field was recalculated. Process Date: October 19,2011 Specific check #5: Built topology. Checked for Gaps and Overlaps. Fixed all. In some gaps, copied polygons from LULC_2004_UPDATE feature class, as it looked as if these polygons in the 2009 feature class had been accidentally deleted. Acres field was recalculated. Process Date: October 20, 2011 Reviewed all combinations of LCCODE / LUCODE, and edited to correct errors. Process Date: November 2011 The GeoPlan Center downloaded the original St. John River Water Management District datasets (see below) from the following FTP site on January 27th, 2012. ftp://secure.sjrwmd.com/disk6b/lcover_luse/lcover2009/LCLU2009_SJRWMD.zip The district-wide dataset LCLU2009_SJRWMD.shp was originally in NAD_1983_HARN_UTM_Zone_17N projection The district-wide layer was reprojected to the FGDL Albers projection. Next the dataset was renamed from LCLU2009_SJRWMD.shp to LU_SJRWMD_2009.shp Next the records in the attribute table were UPPERCASED. Below is the original SJRWMD file structure: ITEM NAME LCCODE LUCODE EDIT_DATE EDITOR COMMENTS LCCOD_DESC LUCOD_DESC Below is the crosswalk table between the original file structure and the new file structure: ORIGINAL NAME NEW NAME LCCODE OTHER LUCODE FLUCCS EDIT_DATE Deleted EDITOR Deleted COMMENTS Deleted LCCOD_DESC Same LUCOD_DESC Same Additionally GeoPlan added and populated the following fields: SOURCE SOURCE2 FLUCCS_L1 LEVEL1 FLUCCS_L2 LEVEL2 FLUCCS_L3 LEVEL3 FLUCCSCOMP ACRES DESCRIPT FGDLAQDATE AUTOID Next GeoPlan ran the Repair Geometry Command 3x. Next GeoPlan ran the Eliminate Polygon Command on ten features whose area was less than 0.001 Acres. Next GeoPlan ran the Repair Geometry Command 1x. Next GeoPlan reviewed the Data layer and cleaned up some issues within the table in order to make sure that the Land cover code (OTHER) and the Land use code (FLUCCS) had the correct matching Land cover code descriptions (LCCOD_DESC) as well as Land use code descriptions (LUCOD_DESC). Next GeoPlan filled in any missing LCCOD_DESC or LUCOD_DESC attributes with the information found within the SJRWMD 2009 Photointerpretation Key. ftp://secure.sjrwmd.com/disk6b/lcover_luse/lcover2009/lu2009_PI_Key/ Process Date: 20120208
