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 ARC/Info basemap coverage
-Add a Route Event theme using the FACROSS info file
-Project the shape file to the standard FGDL projection.
-Export route event to shapefile
-Select railroad features and export to new shapefile
the following selection string was used to find railroads:
("NAME" LIKE '%RR%' OR "NAME" LIKE '%R/R%' OR "NAME" LIKE '%RAILROAD%'
OR "NAME" LIKE '%RAIL ROAD%' OR "NAME" LIKE '%R.R.%'OR "NAME"
LIKE '%R R %'OR "NAME" LIKE '%CSX%' OR "NAME" LIKE '%METRORAIL%')
-Delete Facility Crossings that got included in the selection set that are not railroads.
-Use ArcToolBox to convert lines to points.
-Add DESCRIPT field based on field NAME
