Description:

Abstract: The Rail Junctions layer, along with the Railroads layer, is a comprehensive database of the nation's railroad system. The data set covers all 50 states, the District of Columbia and Puerto Rico. No rail lines exist in American Samoa, Guam, Northern Mariana Islands, and the Virgin Islands of the US. This product is a completed deliverable.

Purpose: This Rail Junctions data set provides points representing rail stations, rail interchange junctions, and end points of rail lines along with an optional name for the location for the Homeland Infrastructure Foundation-Level Data (HIFLD) database (https://gii.dhs.gov/HIFLD). This shapefile was manually converted from its original feature class format by the National Geospatial-Intelligence Agency (NGA) Homeland Security Infrastructure Program (HSIP) Team to mitigate automated conversion errors.

Data Quality Information:

Attribute Value Accuracy Information:

Attribute Accuracy Report: No formal attribute accuracy test was conducted. Data from the authoritative sources (as identified in other sections of this metadata) is assumed to be correct and accurate. See also “Overview Description” in the “Entities and Attributes” metadata section.

Logical Consistency Report: Data were extracted from sources (identified in the SOURCE field) and other open source documents, records, and websites to populate the attribute fields. During quality control, attributes were checked to ensure that they fell within the expected ranges or had expected/valid values. Text attribute values were checked for spelling and usage consistency. No topology tests were conducted. All records were verified to occur within the spatial domain of the shapefile.

Completeness Report: Data is complete.

Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: None; all efforts are made to place the geographic representation of the facility, terminal, station, or control point on-entity using the best available imagery from a wide variety of sources.

Vertical Positional Accuracy:

Vertical Positional Accuracy Report: None; dataset contains no vertical data.

Lineage:

Process Step:

Process Description:

Authoritative data sources are identified through open source research. That data is then acquired and transformed into a usable data format. The properly formatted data then goes through preprocessing steps that includes a geocoding operation to give spatial context to the data. The data goes through further refinement using remote sensing techniques. After preprocessing, every record goes through a review process and each point is moved to an on-entity network location based on interpretation of the best available imagery and open source information.
