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 data was created to serve as base information for use in GIS systems for a 
variety of planning and analytical purposes.

This data is provided 'as is' and its horizontal positional accuracy 
has not been verified by GeoPlan

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'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center

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:
This dataset was created using ESRI event mapping.  The route system is the 
Transportation Statistics' basemap routes.  The event source data are from tabular 
data stored in an Oracle database.  The query used to generate the event source 
data is: 
select * from bridgeno
Process Date: 20081006

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 The data set was originally downloaded in OCTOBER 2008 as the RCI basemap. Specific instructions, created by URS Corporation and the GeoPlan Center, were carried out. 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. -Download the most recent Statewide Personal GeoDataBase -Export from feature class "bridges" to shapefiles -Project the shape file to the standard FGDL projection. -Deleted items OBJECTID_1, OBJECTID,ERRCODE, ERREXPL -Add Descript item based on STRUCTURE Process Date: 20081029
