USER NOTES:

This data is provided "as is". GeoPlan relied on the integrity of the original data layer's topology.

This data is provided "as is" by GeoPlan and is complete to our knowledge.

A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare 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. 1:250000 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 analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References sectionand the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at: http://www.geoplan.ufl.edu/education.html

DATA LINEAGE SUMMARY:

Statewide basins coverage was converted into a shapefile and subdivided into 8 smaller units by Joe Hand. Additional basins were created in ARCVIEW (For information on the procedures and rationale used to subdivide the statewide coverage and create these new basins, contact Joe Hand). The eight shapefiles were used as a source for making an updated statewide 305b coverage. Each shapefile was converted into an ARC/INFO REGIONS coverage using SHAPEARC command with the subclass option. Coverages were projected from Decimal Degrees NAD27 to Albers-Hpgn. Topology was rebuilt using the CLEAN command. A tolerance of 1 was used for fuzzy and dangle length. The regions coverages were converted to ARC polygon coverages using the REGIONPOLY command. The eight polygon coverages were mapjoined using the MAPJOIN command. Sliver polygons (coverage-id = 0) were eliminated with the ELIMINATE command. As a final check, the linework of the coverage was checked using each of the individual eight coverages as a backcover in ARCEDIT. Some additional small slivers were deleted manually in ARCEDIT. To assure that each polygon has a unique WBID (water body id), a summary statistics on item WBID was performed in ARCVIEW. There were 18 duplicated WBID'S. They were reassigned unique WBID'S following the guidelines supplied by Joe Hand. A shapefile was made of this coverage. DBASE tables (containing summaries of chemical and biological data) from the 305b report were joined to the attribute table of the shapefile in ARCVIEW. WBID was used as the joinitem. For a full description of the attribute table contact Joe Hand. The shapefile with the joined attribute table was converted into an ARC/INFO polygon coverage using SHAPEARC (with regions option), CLEAN (fuzzy and dangle length 1) and REGIONPOLY commands. This resulted in the 1996 version of the 305b data. The original datset was updated for 1998 using ArcView 3.1 by updating database information and by adding new polygons to accomodate new stations. The 1998 datset was updated for 2000 using ArcView 3.2 by updating database information and by adding new polygons to accomodate new stations. Process Date: 20000101 GeoPlan downloaded this dataset from the data from the Florida Department of Environmental Protection (http://www.dep.state.fl.us/gis/datadir.asp) (1) Projection file changed to FGDL Albers HPGN (2) Upcased all records in the table (3) Added a DESCRIPT field based on BASIN (4) Added FGDLAQDATE based on Geoplan acquisition date Process Date: 20060615
