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.
GeoPlan relied on the integrity of the attribute information within
the original data.
The RCI is a computerized database of physical and administrative data
related to the roadway networks that are either maintained by or are of
special interest to the Department. In addition to data required by the
Department, the RCI contains other data as required for special Federal and
State reporting obligations. The RCI is maintained by District and Central
Office personnel. While there are many other important databases
maintained by the Department (several that contain more highly technical
data such as bridge specifications, highway design, or pavement) the RCI
remains the largest database with over 1 million records.
(Chapter 1   Page 1 RCI Office Handbook)

The FDOT GIS Functional Classification Roadways feature class provides spatial 
information on the assignment of roads into systems according to the character of 
the service they provide in relation to the total road network.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.

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:

DATA LINEAGE SUMMARY:
The data set was taken from the Florida Department of 
Transportation Statistics Office from the following webpage:  
http://www.dot.state.fl.us/planning/statistics/gis/default.htm
The data set was originally downloaded as the 
RCI basemap and specific instructions, created by URS 
Corporation and the GeoPlan Center, were carried out 
using ArcGIS. The data set is then to be updated on 
a regular basis. The data was originally in UTM Zone 17, 
Nad83, units meters. The data was projected to Albers HPGN.

-this layer was created by following the instructions in the word document:
"ArcGIS process for creating basemap.doc"
-the word document steps you through a procedure that is run in ArcGIS.
-Projected the shape file to the standard FGDL projection.
Process Date: 20100201

Data imported to ArcSDE and exported as a shapefile. Process Date: 20100323
