Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The District performed an accuracy assessment on the data to compare in-field classification to photointerpreted map classification. 90 random sample points of polygons coded were generated of which 75 were seagrass and 15 were Tidal Flats. The sites were located in the field with a Global Positioning System (GPS). A 90% accuracy rating for seagrass categories based on the 75 randomly selected seagrass sample points was required.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

For positional accuracy the data meets USGS National Map Accuracy Standards for 1:12000 scale maps.

Process_Step:

Process_Description:

Aerial photography was scanned at 13 microns at 1:24000 providing a 1 foot Ground Sample Distance or 12" pixel resolution digital image and existing Continuously Operating Reference Stations(CORS) in Tampa were used for GPS collection. Seagrass data were stereoscopically photointerpreted from 1:24000 scale natural color aerial photography.The FDOT Florida Land Use, Cover and Forms Classification System (FLUCCS) was used, in modified form, to code features within the 2004 SWIM study area boundary. Minimum mapping unit (mmu) for all classes was 0.5 acres. Ground truthing was performed during the photointerpretation phase to ensure classification accuracy and consistency of PI with existing 2001 seagrass data. Seagrass previously mapped in 2004 within the passes were not delineated in 2006 because of high turbidity. This omission resulted in some 'false' change polygons in the 2006 update. Digital compilation of the new baseline maps was carried out by photointerpreters experienced in seagrass delineation, using Kork Digital Stereo Plotters (KDSP). KDSP allows stereo viewing of the imagery with panning/zoom capabilities so that accurate and detailed photointerpretation can be accomplished.The softcopy stereoplotters have vector superimpositioning capabilities allowing photointerpreters to superimpose digitized linework and labels over imagery during the photointerpretation process.The automatic and interactive editing capabilities greatly simplify and speed up the editing phase of a mapping project. 2001 Seagrass data was referenced as collateral information during the compilation process.

Process_Step:

Process_Description:

Kork Digital Stereo Plotter (KDSP) files were converted to dxf files for exportatation into ARC/Info to run automated validation routines. Quality control checks for digital data consisted of unlabeled, multi-labeled and contiguous polygon errors as well as dangles and sliver polygons. Polygon topology was created and label errors and node errors were run in ARC/Info. Coverage characteristics were adhered to, as specified by the contract (tolerances, projection definition, PAT items etc.). Segment data was extracted using the segment coverage provided by the District. Acreage calculations were derived from the ARC/Info coverages and delivered in EXCEL spreadsheet format.The coverages were converted to a shapefile for final delivery.

Process_Step:

Process_Description:

The shapefile was imported into SDE using ArcGIS 9.2. The feature classes were created with column names, shape type, grid size, and projection information defined during creation. An X/Y Domain and Precision were set at MinX: -700,000; MinY: 2,000,000; Precision: 1000. Z-Values were set at MinZ: -20; Precision: 1000. The Grid Tile Size is 100,000. Data was then loaded into the feature classes from the coverages using the 'Load Data' tool in ArcCatalog 9.2. FLUCCSCODE indexes were created for attributes when there were more than 100 records in the data set.
