USER NOTES:








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)















A note concerning data scale:

Scale is an important factor in data usage. Certain scale 
datasetsare 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.

1:250000 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 analyses. Every 
effort has been made to supply the user with data 
documentation. For additional information, see the 
References sectionand the Data Source Contact section of 
this documentation. For more information regarding scale 
and accuracy, see our web pages 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 2006 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 TM 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: 20060401
