GENERAL DESCRIPTION:
This dataset from the National Highway-Rail Crossing Inventory Program represents highway-railroad grade crossing intersections where a highway crosses a railroad at-grade. Grade crossings may be public or private. Public grade crossings are roadways that are under the jurisdiction of, and maintained by, a public authority. Private grade crossings are on roadways privately owned, such as on a farm or industrial area, and is intended for use by the owner or by the owner's licensees and invitees.

USER NOTES:
The quality of the inventory can vary because a record of grade crossing location 
is being maintained by each state and railroad that is responsible for maintaining its 
respective information.
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.
Highway-rail grade crossing means a location where a public highway, 
road, street, or private roadway, including associated sidewalks and pathways, 
crosses one or more railroad tracks at grade.

Rail Crossings is a spatial file maintained by the Federal Railroad Administration 
(FRA) for use by States and railroads. The program is to provide information to 
Federal, State, and local governments as well as the railroad industry for the 
improvements of safety at highway-rail crossing.

The spatial quality can vary on who is updating the inventory record.  Quality 
checks are performed on the spatial file.  A process of applying a county bounding 
box limit for a particular State and County is applied.  If the location falls outside of 
the bounding box for the state and county then the record does not get processed 
into the spatial file.

This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. 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:

DATA LINEAGE SUMMARY:
The data is downloaded from the HWY-Rail Crossing Inventory Files.  Quality 
checks are performed on the spatial and attribute data.  The spatial checks were 
described under the positional Accuracy.  The attribute check will review the 
consistence of the attributes.
