Description:
Abstract:
The railroad data set was generated for the Front Range Infrastructure
Resources (FRIR) Project as a base cartographic layer. The data set
contains the project's 45 1:24,000-scale quadrangle demonstration area
that covers the Front Range of Colorado, south from Ft. Collins to the
southern portion of Denver metropolitan area (not including Highlands
Ranch, Douglas County); and west from Denver International Airport to the
eastern foothills of the Rocky Mountains. For more information on this
project, visit the Colorado Front Range Infrastructure Resources Project
web site: http://rockyweb.cr.usgs.gov/frontrange/datasets.htm
Procedures involved in compiling the railroad data include (1) obtaining 1
meter digital imagery and ancillary data for collecting, interpreting, and
classifying the railroad features, (2) compiling the Digital Line Graph
(DLG) vector data by 1:24,000-scale USGS quadrangle tiles, (3) merging the
1:24,000-scale quadrangle tiles into one seamless data set, and (4)
translating and reattributing the features into user-friendly data sets.
The translated attribution is described below in the Supplemental_Information section.
Purpose:
The demand for GIS data has increased recently, especially in rapidly
growing metropolitan areas. Many state, regional, and local planning
agencies require up-to-date transportation networks and other cartographic
base information for various applications including modeling urban growth,
determining land suitability for future development, monitoring land use
changes and impacts on the environment, understanding land use patterns,
and developing policies that could encourage or discourage certain land
use zoning.
Base cartographic layers are part of the USGS FRIR project cooperative
effort to provide qualitative and quantitative information about
infrastructure (aggregate, energy, water, habitat) features needed by
growing urban regions like the Denver metropolitan area. The objective of
the project is to develop GIS information about water and other themes in
such a way that decision makers can use this information to make land use
planning decisions, growth models and will be used by the project
scientists for multiple studies of the changing landscape of the Front
Range and the impact on various resources.
In addition to railroads (FRIRR), the USGS has created six other base
cartographic layers consisting of: roads (FRIRD), hydrography (FRIHY),
miscellaneous transportation (FRIMT), manmade structures (FRIMS), public
land survey system (FRIPL), and boundaries (FRIBD). FRIRR contains line
and polygon attributed features. The data layers are available at
http://rockyweb.cr.usgs.gov/frontrange/datasets.htm
Supplemental_Information:
CODES: RAILROAD OVERLAY This document lists the codes specific to the
railroad coverage as they pertain to item fields. The original
classification system is taken from DLG major/minor attribute codes. The
CAT item specifies the overlay type and takes the place of DLG major
codes. See http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html for
the complete document of DLG attributes.

This data was collected from 1-meter resolution orthorectified scanned
imagery (1997). The IFSAR imagery was used for horizontal accuracy. The data
is revised from the original DLG vector data that was collected at
1:24000-scale within the 40 foot map accuracy standards. See DLG standards
at http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html
The data was collected for government use and represents the results of data
collection for a specific activity. USGS makes no representation as to the
suitability or accuracy of the data for any other purpose and disclaims any
liability for errors that the data may contain. As such, it is only valid
for its intended use, content, time, and accuracy specifications. While
there are no explicit constraints on the use of the data, please exercise
appropriate and professional judgment in the use and interpretation of this
data.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribution for the railroad data was verified for consistency
throughout the demo project area. Check plots were used to compare
attribution and spatial extent with the photography. See Part 3, Attribute
Coding of Standards for Digital Line Graphs at
http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html
See Entity_and_Attribute_Information and Supplemental_Information
Logical_Consistency_Report:
Polygon and chain-node topology present. All areas are closed polygons
containing one label point. All arcs have an attribute code.
Completeness_Report:
Railroad feature density consists of lines with various railroad attributes.
Polygons will carry a railroad yard or have no attributes. There are no node
attributes. The region is considered a representative pattern (feature
density) with capture conditions according to USGS 1:24000 mapping
standards. Use of this data at larger scales may be incomplete.
See capture conditions in Part 2- Railroads (DLG-F), and also Standards for
Digital Line Graphs and at
http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The railroad vector data is within 40 ft. to the ground planimetry. The
original data is from a mosaic of photorevised 1:24000-scale DLGs
derived from stable-base 1:24000-scale USGS topographic maps. Digital
orthorectified imagery at a 1-meter resolution was used to collect
features. Magnitude imagery from IFSAR (Interferometric Synthetic
Aperture RADAR), with a horizontal accuracy of 2.5 meters and vertical
accuracy of 2.0 meters, was used to verify horizontal placement of the
features. The IFSAR imagery was collected by Intermap Technologies. See
National Map Accuracy Standards at

features.
Process_Step:
Process_Description:
Interpretation/Compilation - Features were visually identified,
interpreted, and classified according to the USGS DLG Limited Update
Standards except that data was collected so that 90 per cent of the
well-defined features are within 40 ft. to the ground planimetry. The
data is interpreted and compiled in blocks of 1:24,000-scale
quadrangles. Once completed the data is edge-matched and paneled
together into the seamless demonstration area. Final review of the data
was to verify attribution, add additional attribution, and move features
to geographically match the imagery.

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview:
FRIRR items are used to describe the physical and cultural characteristics
of line and polygon elements. Attribute codes are used to reduce redundant
information, provide enough reference information to support integration
with larger data bases, and describe the relationships between
cartographic elements.
See Supplemental_Information for item definitions.
