FEATURE ATTRIBUTE TABLES CODES AND VALUES:
Item | Item Description | |
OBJECTID |
Internal feature number. |
|
ID |
The link ID in the network structure. |
|
LENGTH |
Length of the segment |
|
FRAID |
The link ID in the network structure. |
|
NET |
Use status.
|
|
RROWNER1 |
The reporting mark of the 1st owning railroad. A mark of 'XXXX' indicates an abandoned link. Rule 260 codes are used where available. A mark of 'DUMX' indicates an added connecting link. |
|
TR1 |
Reporting mark of the 1st railroad having trackage-rights. |
|
TR2 |
Reporting marks of any additional railroads having trackage rights. |
|
TR3 |
Reporting marks of any additional railroads having trackage rights. |
|
TR4 |
Reporting marks of any additional railroads having trackage rights. |
|
BR1 |
The reporting marks of any railroad which does the billing for either |
|
BR2 |
The reporting marks of any additional railroad which does the billing |
|
PREVRR1 |
The reporting mark of the last carrier to own/operate the line if known, rule 260 Code. |
|
PREVRR2 |
The reporting mark of the carrier owning the line in the near post-WWII period, rule 260 Code. If the current owner or subsidiary road owned the line, the mark is not repeated. |
|
ABANDONED |
Abandoned flag
|
|
PASS |
Type of passenger rail flag
|
|
MILITARY |
Type of military interest flag - this code should match the publication 'Civil Rail Lines Important to 'National Defense, September, 2003'.

|
FRA_REG |
FRA region number (Leading zeros count)
|
|
DENSITY |
Density Category for the latest year available, 2003.
|
|
RR_CLASS |
Railroad classification code. Filled for all CLASS 1 railroads and most CLASS 2 & 3.
|
|
SIGNALS |
Type of signaling system.
|
|
LAST_DEN |
The density code for the previous year. This value uses the same values as the latest year's density code above.
|
|
RAILROAD |
Rail name |
|
FROM_FRAID |
The FRA assigned node number at the topological start of the link |
|
TO_FRAIDN |
The FRA assigned node number at the topological end of the link |
|
STFIPS |

The network is not topologically connected. There should be no redundancy of lines or nodes in the data set. The data set is geographically accurate at the 1:100,000 scale. RITA/BTS quality checks were to cross reference the place dataset with the state dataset, to determine that the spatial data and attribute data were accurate |
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 data are created to serve as base information for use in GIS systems for a variety of planning and analytical purposes. |
The horizontal accuracy for these data can be stated as being that associated with data compiled at the 1:100,000 scale. |
This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan |
THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. 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: http://geoplan.ufl.edu/education.html |
