Abstract:
The Public Land Surveys 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: (URL:http://rockyweb.cr.usgs.gov/frontrange/datasets.htm)
Procedures involved in compiling the PLSS data include (1) Obtaining the Digital Line Graph (DLG) vector data by 1:24,000-scale USGS quadrangle tiles, (2) merging the 1:24,000-scale quadrangle tiles into one seamless data set, and (3) 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 boundaries 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 boundaries 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 PLSS, the USGS has created six other base cartographic layers consisting of: roads (FRIRD), miscellaneous transportation (FRIMT), railroads (FRIRR), manmade structures (FRIMS), boundaries (FRIBD), and hydrography (FRIHY). The PLSS coverage FRIPL contains line and polygon attributed features. The data layers are available at http://rockyweb.cr.usgs.gov/frontrange/datasets.htm

CODES: PLSS OVERLAY 
This document lists the codes specific to the 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.

The Public Land Survey System (PLSS) data in this coverage originated from 7.5-minute USGS Digital Line Graph PLSS files in North American Datum 1927. These files were paneled together into a single coverage and the coverage was re-projected to North American Datum 1983. No attempt was made in the coverage to clip overshoot data or extend undershoot data resulting from the datum shift.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribution for the PLSS data was verified for consistency throughout the demo project area. Check plots were used to compare attribution and spatial extent. See Part 3, Attribute Coding of Standards for Digital Line Graphs at (http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html)
Logical_Consistency_Report:
Polygon and chain-node topology present. All areas are closed polygons containing one attributed label point. Arcs have an attribute code if appropriate.
Completeness_Report:
The Land Survey System (PLSS) and other special surveys within, and exclusions within, and exclusions from, public domain lands are shown on USGS quadrangle maps. Survey corners, lines, and areas within the public domain States are mapped and collected as DLG-3 data. The data was converted to the FRIPL data set. The attributed lines, and polygons reflect the translated attribution described in the Supplemental_Information section. Nodes (PLSS section corner or PLSS closing corner) are unattributed.

Overview_Description:
Entity_and_Attribute_Overview:
FRIPL 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.
