Description:
Abstract:
Land cover and land use in the St. Johns River Water Management District based on 2009 color infrared aerial photography. This layer is a copy of the 2004 lulc dataset, with updates based on conditions in the 2009 photography.
A detailed Photointerpretation Key is available at http://www.sjrwmd.com/gisdevelopment/docs/themes.html
Purpose:
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.
Supplemental_Information:
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 vegatation 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 brushland (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.

Source_Contribution:
The 2009 layer is based on the 2004 land use / land cover layer, with revisions made to accomodate: a) thematic changes dictated by updates to the PI Key and classification system, and b) thematic and boundary changes indicated by the 2009 orthophotos.
Process_Step:
Process_Description:
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_Description:
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.

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.

Overview_Description:
Entity_and_Attribute_Overview:
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.

*** LUCODE VS. 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
