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 section and 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>

a - t - Identifies individual subEDAs found in estuaries where subEDAs have been defined (e.g., Chesapeake Bay). Only EDAs have subEDAs. w - Identifies those polygons in an EDA not already assigned to a subEDA. The reamining core of the major EDACDA Watershed. Applies only to EDAs that have subEDAs. x - All other polygons. These include all major watersheds (EDAs) that do not have SubEDAs.
