Data development is a component of the Efficient Transportation Decision Making Process (ETDM).
For more information about these initiatives an on-line search using keyword 'ETDM' will provide a number of resources. A listing of relevant documents and resources is included under: <http://fdotenvironmentalstreamlining.urs-tally.com/Library/default.htm>.
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>

The incorporated area is mapped in a uniform and consistent method.
County boundaries are used to represent the boundaries of each service provider area, as this is a county-wide function. All counties in the project area are included. Sub areas, if they exist within or between counties, are not included.
The county boundaries available from the US Census Bureau were downloaded from the University of Florida Geoplan website at www.fgdl.org. Attribute fields were deleted and added to conform to sociocultural data specs. The attribute fields were populated based on information received from the Planning Councils. February, 2005 to June, 2005
The polygons from the St. Johns River Water management District representing county boundaries were downloaded and attributed. They were then exported as a shapefile.
GeoPlan received this data, via CDROM, and performed the following: -Reprojected to the FGDL Albers HPGN map projection. -Restructured the attribute table to fit the SCE Data Specification Document Standards. -Merged datasets together to create one FDOT District-wide shapefile. -Added FGDLAQDATE field based on the date FGDL acquired the data from the source. -Added 'DESCRIPT' field based on name.
