FEATURE ATTRIBUTE TABLES CODES AND VALUES:

ITEM	      ITEM DESCRIPTION

SHAPE        Data attribute inherent to the ESRI shapefile format,
             which defines the data as a point, polyline, or polygon.

ROADWAY      Road system designation used by RCI as the roadway identifier.

ROAD_SIDE     Side of the road
                  C - Center
                  L - Left
                  R - Right

OFFSET_DIR   Offset Direction (This is relevant only for a divided road, where each side 
             (each direction of travel) has two sides, the inside (closer to the median) and 
             the outside (away from the median).
                  1 - Right and Left
                  2 - Right
                  3 - Left

BEGIN_POST   Start measure of the route in miles from RCI.

END_POST     End measure of the route in miles from RCI.

SHLD_ORDER   Characteristics for outside shoulder type
                  1 - closest shoulder to the roadway
                  2 - next closest
                  3 - farthest

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) 

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.

1:250000 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:

http://www.geoplan.ufl.edu/education.html
This dataset has been updated from the previous version on FGDL 3.0.

FGDL QUALITY ASSURANCE STATUS:

-Download the most recent Statewide ARC/Info basemap coverage 
-Add a Route Event theme using the shldtype info file
-Add a description field to be associated with the shoulder type
 values based on the following values:
      
      SHLDTYPE       DESCRIPT
         0           RAISED CURB
         1           PAVED
         2           PAVED WITH WARNING DEVICE
         3           LAWN
         4           GRAVEL/MARL
         5           VALLEY GUTTER
         6           CURB AND GUTTER
         7           OTHER
         8           CURB WITH RESURFACED GUTTER

-Export from Route Event to Shapefile
-Update the Length field with the length (in meters) for each segment
-Project the shape file to the standard FGDL projection.

DATA LINEAGE SUMMARY:

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/default.htm
The data set was originally downloaded in July 2004 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.
