OBJECTID	Internal feature number.
FLUCCS	The land use and land cover classification code as defined in the Florida DOT's FLUCCS classification system. The following represents the original field from the source Water Management District layer.SWFWMD = FLUCCSCODE - The Land Use/Land Cover classification code as defined in the Florida Department of Transportations (DOT) Florida Land Use and Land Cover Classification System (FLUCCS). This is also considered Level 4. SWFWMD uses an adopted classification scheme, for more information on the adopted classification scheme please the Attribute Overview Description Section.

USER NOTES:

The 2005 Land Use/Classification dataset was used as the base starting point, in the creation of the 2006 Land Use/Classification dataset. Photointerpretation (at a scale of 1:12000) and edits (at a scale of 1:8000) were performed on the 2006 Land Use/Classification dataset directly on screen. Quality Control (QC) was performed on screen.

There are no significant omissions.

GeoPlan relied on the integrity of the attribute information within the original data. No statistical accuracy verifications have been done. Based on past projects of a similar nature it is estimated that classification accuracies of between 80% - 90% can be expected. During the edit process, only the FLUCCSCODE was updated. Once the entire area was complete, the LEV1, LEV2, LEV3, and LEV4 attributes were calculated from the FLUCCSCODE. A script was written that updated the FLUCSDESC attribute based on the FLUCCSCODE.

Because water management boundaries do not follow county boundaries, some counties have partial coverage of the land use data. Here is a list of the counties that make up the district, with an indicator of which counties have partial coverage. Alachua County (Partial Coverage), Charlotte County (Partial Coverage), Citrus County, DeSoto County, Glades County (Partial Coverage), Hardee County, Hernando County, Highlands County (Partial Coverage), Hillsborough County, Lake County (Partial Coverage), Lee County (Partial Coverage), Levy County (Partial Coverage), Manatee County, Marion County (Partial Coverage), Orange County (Partial Coverage), Osceola County (Partial Coverage), Pasco County, Pinellas County, Polk County (Partial Coverage), Sarasota County, and Sumter County.

This data layer was created to illustrate the different land uses in the Southwest Florida Water Management District as seen in 2006. This may be useful for future management applications regarding land use change detection.

Visual inspection of the 2006 linework over the 1ft digital aerial photographs, at a scale of 1:8,000, was used to verify the positional placement of the linework. The 2005 land use and land cover data was used as reference data. Photo interpretation, editing and QC (quality control) were performed directly on screen. Data is estimated to be compliant with the National Map Accuracy Standards for 1:12,000, estimated +/- 33.3 feet. The goal of this project was to update the existing 2005 land use and land cover data layer using the 2006 1ft digital aerial photographs that meet or exceed National Map Accuracy Standards for 1:12,000. Land use and land cover boundaries are not always well defined, however, given the use of ancillary data sources (e.g. soils data or National Wetlands Inventory) to determine feature boundaries, it is expected that data acreage should be accurate.

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. 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. For more information regarding scale and accuracy, see our webpage at: http://geoplan.ufl.edu/education.html SWFWMD USE CONSTRAINTS: These data were not collected under the supervision of a licensed Professional Surveyor and Mapper. Use of these data requires a general understanding of GIS.

DATA LINEAGE SUMMARY:

The 2005 Land Use/Classification dataset was used as the base starting point. The 2005 feature class (fc) was copied and renamed to 2006 in a versioned SDE database instance. The 2006 Land Use/Land Cover mapping standards remained the same as last year: 1) it must fit feature boundaries at a scale of 1:12,000, 2) a minimum mapping unit of .5 acres for wetlands and 3) a minimum mapping unit of 5 acres for uplands. The FDOT's Florida Land Use, Cover and Forms Classification System (FLUCCS) was used to classify all features. Ancillary data sources were used to the fullest extent to ensure proper delineation of land use/cover features. These data sources included: 1984, 1990, 1994/1995 color infrared aerial photography; 1990 and 1995, 2004 and 2005 land use/cover, National Wetlands Inventory 1:24,000 maps, NRCS county soil surveys and SWFWMD aerial mapping sheets. Any features that could not be reliably interpreted were field reviewed. Versioning and disconnected editing functions were implemented for the digital update process. From the default SDE version of the 2006 land use data, a QC1 version was created. From the QC1 version, disconnected edit versions were created by each editor covering smaller areas/tiles. Edits were performed on the editor version and when finished it was checked back in to the QC1 SDE version. Any conflicts between QC1 and editors' versions were resolved by accepting the edit changes, or keeping the original line work in QC1. Conflicts were looked at manually to determine which line work to keep. QC1 was subsequently reconciled to Default. Conflicts, if any, were resolved. All children versions were deleted and the database was compressed. QC1 was re-created and the process continued until the district wide update was complete. Land use and land cover features were delineated, on screen, using the 2006 1ft digital aerial photographs as a back drop. Edits were made, using heads-up digitizing in ArcMap, on the feature class in the personal geodatabase created with the disconnected edit function. Line work and labels were added, deleted or reshaped on screen. Topology Rules, no overlaps and no gaps, were created and verified on the personal geodatabase. Process Date: 20070701 - 20071022 The GeoPlan Center downloaded the original Southwest Florida Water Management District datasets (see below) from the following website on May 22st, 2008. http://www.swfwmd.state.fl.us/data/gis/libraries/physical_dense/lu06.htm http://ftp.swfwmd.state.fl.us/pub/gisdata/physical_dense/lu06/ lu06-arcad_ne.exe lu06-arcad_nw.exe lu06-arcad_se.exe lu06-arcad_sw.exe lu06-barto_ne.exe lu06-barto_nw.exe lu06-barto_se.exe lu06-barto_sw.exe lu06-charl_ne.exe lu06-ftmye_nw.exe lu06-gaine_sw.exe lu06-inver_ne.exe lu06-inver_nw.exe lu06-inver_se.exe lu06-inver_sw.exe lu06-kissi_nw.exe lu06-kissi_se.exe lu06-kissi_sw.exe lu06-ocala_ne.exe lu06-ocala_nw.exe lu06-ocala_se.exe lu06-ocala_sw.exe lu06-orlan_nw.exe lu06-orlan_sw.exe lu06-saras_ne.exe lu06-saras_nw.exe lu06-saras_se.exe lu06-saras_sw.exe lu06-stpet_ne.exe lu06-stpet_nw.exe lu06-stpet_se.exe lu06-stpet_sw.exe lu06-tarpo_ne.exe lu06-tarpo_nw.exe lu06-tarpo_se.exe lu06-tarpo_sw.exe Each dataset was downloaded and unzipped. Next the datasets were merged to create one district wide layer. Next the district wide layer was dissolved (single part) on FLUCCSCODE, to remove the feature lines created at the original dataset boundaries, this was done to create a more uniform district wide layer. The district wide feature count went from 271007 to 265803 features upon completion of the dissolve. PLEASE NOTE: It is possible that A few of the polygons found on the interior of the datasets were dissolved into adjoining polygons with the same FLUCCSCODE. 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 records in the attribute table were UPPERCASED.
