What does this data set describe?

Title:
Digital Map of surficial geology, wetlands, and deepwater habitats, Coeur d'Alene River Valley, Idaho.
Abstract:
The surficial geology, wetlands, and deepwater habitats of the Coeur d' Alene River Valley, Idaho were mapped by Arthur A. Bookstrom and Stephen E. Box (1996-1998) onto 1:24,000 scale topographic base maps (stable-base greenline mylars) for input into an Arc/Info geographic information system (GIS).
Supplemental_Information:
These GIS datasets were requested by the U.S. Fish and Wildlife Service and were prepared in conjunction with the Coeur d' Alene Tribe as part of a National Resource Damage Assessment (NRDA) being developed by the U.S. Department of the Interior in conjunction with the Environmental Protection Agency and the Department of Justice.
Geologic features are mapped on the river-channel bottom, its marginal meander ridge, and highlands above the floodplain. Wetland features are mapped according to the Wetlands Classification System of the U.S. Fish and Wildlife Service, which includes riverine, palustrine, and lacustrine systems. Modifiers denote predominant vegetation which indicates frequency and duration of inundation, water depth, organic content, and oxidation of sediments. For detailed descriptions of the geologic and wetland systems data model, please call Arthur Bookstrom (509) 368-3119.

    Entity_and_Attribute_Overview:
    The Coeur d'Alene GIS includes four geospatial datasets: cdasurf, cdahydro, cdanest, and cdapump. The primary dataset, cdasurf, consists of an arc attribute table, cdasurf.aat, that relates to the cdasurf.con (contact) and cdasurf.bnk (banktype) files; and a polygon attribute table, cdasurf.pat, that relates to the cdasurf.map (detailed geologic and wetlands map units), cdasurf.sys (wetland system), cdasurf.cls (wetland class), cdasurf.scl (wetland subclass), cdasurf.fpl(floodplain designation), cdasurf.wtr (water regime), cdasurf.sed (lithology), cdasurf.rdx (oxidation/reduction environment), cdasurf.ph (pH status), cdasurf.agl (agricultural land) files. The cdahydro dataset consists of an arc attribute table, cdahydro.aat, that relates to the cdahydro.sym (hydrologic features) file. The cdanest dataset consists of an arc attribute table, cdanest.aat (canals and moats surrounding waterfowl nesting mounds), and a polygon attribute table, cdanest.pat (waterfowl nesting mounds). The cdapump dataset consists of a point attribute table, cdapump.pat (surfacewater pumping stations).

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

  2. Who also contributed to the data set?

    Arthur A. Bookstrom and Stephen E. Box mapped the surficial geology and wetland system units (1996-1998); Berne L. Jackson (Coeur d'Alene Tribe) scanned the original stable-base 1:24,000-scale maps and created and attributed the GIS with preliminary labels and linecodes. Theodore R. Brandt (contractor) created the master Arc/Info registration file and converted the preliminary GIS to Idaho state plane format. He also digitized in new linework, edited the digital files, and built lookup tables with detailed wetland system, geologic, lithologic, and metal contamination information; Pamela D. Derkey (USGS) provided technical assistance with the geologic-wetland systems data model, metadata, digital documentation, and map projections; Steven R. Munts (contractor) assisted with digital editing; Julie Campbell (USFW) reviewed marsh and lacustrine systems for correctness. She also reviewed vegetation classes and subclasses.

Why was the data set created?

The purpose of these GIS datasets is to show how the distribution of floodborne contaminated sediments is related to potential sources of clean and contaminated sediments, and to hydrologic features that determine patterns of erosion, transport, and deposition. Mapped geologic information indicates the configuration and distribution of surficial geomorphic features and sedimentary deposits that result from erosion, transport, and deposition of unconsolidated sediments. Mapped wetland features indicate the configuration and distribution of surficial hydrologic pathways that guide erosion, transport, and deposition. These GIS datasets are intended to aid in process- oriented interpretation of geochemical and biological data being collected as a basis for natural-resource damage assessment and restoration planning.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Attribute accuracy was verified by manual comparison of the source with hard copy printouts and plots.

  2. How accurate are the geographic locations?

    The horizontal positional accuracy for the digital data in no better than +/- 2 meters based on the digitizing RMS error.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Data is principally from geologic interpretation of color aerial photographs and LANDSAT TM images with field checking by A.A. Booksrom and S.E. Box. Some bedrock geologic information is from Griggs (1973). In general, the minimum mapping unit is approximately 50 square meters.

  5. How consistent are the relationships among the observations, including topology?

    Polygon and chain-node topology present. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
