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>
(Creation of the basin-24 (area) dataset) In Spring of '97, the data was converted from NAD27 to HPGN using the Arc/INFO projection command within Arc/INFO version 7.0.4.
One coverage of the entire state, excluding South Florida was digitized using ARC/INFO. The South Florida coverage was digitized by SFWMD from USGS mylars of 7.5' quads dated 1978-1979 by engineers familiar with the landscape using ARC/INFO 6.1.1. The two coverages were joined to form a statewide coverage using the update command, then polygon slivers were eliminated. Check plots were made. The coverage was converted to Albers Conformal Area projection and exported from the VAX VMS system using ARC/INFO. On the DEC/ALPHA UNIX system, the export file was imported and inserted into the (quad) library. Since the original creation of the WBIDS spatial dataset recommended changes to the linework by basin rotation staff and outside professionals have been incorporated on a case by case basis. These changes are documented in the CHANGES Coolum of the dataset. During August of 2003 the ARC coverage was converted into a Geodatabase to facilitate the editing process in ARCGIS. Geodatabase is joined to Access IWR database to get information in specific waterbodies.

Dataset copied.
- A DESCRIPT field was added based on BASIN_1. - FGDLAQDATE was added based on date downloaded from source. - AUTOID field was added. - Renamed file from WBIDS to wbids_apr08. - Deleted Object_ID field. - Upcased all records in the table
