USER NOTES:


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 û Page 1 RCI Office Handbook) 

A note concerning data scale:

Scale is an important factor in data usage. Certain scale datasets
are not suitable for some project, analysis, or modelling 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 section and the Data Source 
Contact section of this documentation. For more information
regarding scale and accuracy, see our web pages at:

FGDL QUALITY ASSURANCE STATUS:

-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 8.3.
-Projected the shape file to the standard FGDL projection.

DATA LINEAGE SUMMARY:

The data set was taken from the the Florida Department of Transportation Transportation
Statistics Office from the following webpage:  http://www.dot.state.fl.us/planning/statistics/gis/default.htm
The data set was originally downloaded in June 2004 as the RCI basemap and specific
instructions, created by URS Corporation and the GeoPlan Center, were carried out using ArcGIS 8.3.
The data set is then to be updated on a regular basis. The data was orginally in UTM Zone 17, Nad83, units meters.
The data was projected to Albers HPGN.
