This data is provided 'as is'. GeoPlan relied on the integrity of the original data layer's topology |
This dataset contain all existing rail bridges that cross the hydro features in NTAD's hydropolygon and waterways shapefiles. It should not be considered fully comprehensive as it does not include bridges over hydro features which are not in the two shapefiles mentioned above. It also does not contain rail bridges that crossover non-hydro features. |
GeoPlan relied on the integrity of the attribute information within the original data. |

Railroad Bridges is a spatial file maintained by the Federal Railroad Administration (FRA) and Research and Innovative Technology Administration (RITA)/Bureau of Transportation Statistics (BTS) for use in national and regional spatial analysis |

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.

Using a customized GIS tool, a point was placed where the NTAD 100K rail network dataset intersected NTAD's hydroline (polygon) and waterway (polyline) datasets (when the rail lines crossed the hydroline dataset, two points were created). Each point(s) was then reviewed individually by an analyst, and there was the ability to accept, reject, or have someone else look at the point. If the point was accepted, that point would then be placed in a point shapefile (when there were two points and after it had been accepted, another point was added in the middle of the two originally points). Specific attribute data from the 100K rail line and the hydroline/waterway datasets were then populated into the new rail bridge shapefile. Process Date: 2010 |
