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.

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 StatisticsOffice from the following webpage:  
http://www.dot.state.fl.us/planning/statistics/gis
The data set was originally downloaded in April 2007 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
