Description:
Abstract:
The hydrography data sets were 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 hydrographic data include (1) obtaining 1 meter digital imagery and ancillary data for collecting, interpreting, and classifying the hydrographic 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 hydrographic 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 hydrography, the USGS has created six other base cartographic layers consisting of: roads (FRIRD), miscellaneous transportation (FRIMT), railroads (FRIRR), manmade structures (FRIMS), public land survey system (FRIPL), and boundaries (FRIBD). There are two hydrography data sets, FRIHY contains line, polygon, and node attributed features and the FRIHYX contains point attributed features. The data layers are available at http://rockyweb.cr.usgs.gov/frontrange/datasets.htm

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribution for the hydrography 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_Identification.
Logical_Consistency_Report:
Polygon and chain-node topology present. All areas are closed polygons containing one label point. All arcs have an attribute code, nodes will have an attribute code if appropriate. The data set will have an unattributed polygon if not a hydrographic feature.
Completeness_Report:
Hydrographic feature density consists of flowing water, standing water, manmade hydrographic structures, and wetlands. 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.
Reservoirs and pond/lake attributes are used interchangeably in some areas, with pond/lake being the most frequent and reservoirs representing man-made water bodies. This can be attributed to the map interpreter collecting the data. Both streams and ditches appear as single and double-lined. Polygons smaller than 50 ft. were collected as point features in Coverage FRIHYX. Point features e.g.-wells, springs, windmills, pump stations, gaging stations, and polygons smaller than 50 ft. are collected in the FRIHYX coverage.
See capture conditions in Part 2- Hydrography, Standards for Digital Line Graphs at http://rockyweb.cr.usgs.gov/nmpstds/dlgstds.html
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The hydrographic 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 http://mapping.usgs.gov/standards/

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.
