What does this data set describe?

Title:
Geologic map and database of the Roseburg 30 x 60 minute quadrangle, Douglas and Coos Counties, Oregon
Abstract:
This digital map database, largely compiled from new mapping by the authors, represents the general distribution of bedrock and surficial deposits of the Roseburg 30 x 60 minute quadrangle along the southeastern margin of the Oregon Coast Range and its tectonic boundary with Mesozoic terranes of the Klamath Mountains. Together with the accompanying text files as PDF (rb_geol.pdf), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps is 1:24,000, but the Quaternary contacts and structural data have been much simplified for the 1:100,000-scale map and database. The spatial resolution (scale) of the database is 1:100,000 or smaller.

      UTM_Zone_Number: 10
      Transverse_Mercator:

  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    Because these data were created in Arc/Info, polygons are described by tables fitting the pattern cover.pat (here and after, "cover" refers to the name of the Arc/Info coverage). These contain the general attributes AREA, PERIMETER, cover#, and cover-ID. Likewise, lines are described by tables named cover.aat, and contain topological as well as general attributes FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, cover#, and cover-ID.
    Because these data were created using Alacarte, the feature attribute tables also include the attributes LTYPE for lines and PTYPE for points and polygons, as well as SEL, which is used internally by Alacarte to mark features that are selected, and SYMB, which is used internally by Alacarte to symbolize the features for display. Additional attributes that contain scientific information may also be present, and are described in detail here.

Why was the data set created?

This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:100,000) scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the regional scale of this report does not provide sufficient detail for site development purposes. In addition, this map does not take the place of fault-rupture hazard zones designated by the Oregon State Geologist. Similarly, the database cannot be used to identify or delineate landslides in the region.

    Date: 1990 (process 2 of 3)
    The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California, with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The files are in either GRID (ARC/INFO raster data) format or COVERAGE (ARC/ INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 7.x). ARC/INFO export files (files with the .e00 extension) can be converted into ARC/ INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems, such as MapInfo via ArcLink and ESRI's ArcView (version 1.0 for Windows 3.1 to 3.11 is available for free from ESRI's web site: http://www.esri.com). The digital compilation was done in version 7.1.1 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The geologic map information was digitized from stable originals of the geologic maps at 1:24,000 scale. The author manuscripts (pen on mylar and pen on paper) were scanned using a Ideal rasterizing color scanner with a resolution of 600 and 400 dots per inch. The scanned images were vectorized and transformed from scanner coordinates to projection coordinates with digital tics placed by hand at quadrangle corners. The scanned lines were edited interactively by hand using ALACARTE, color boundaries were tagged as appropriate, and scanning artifacts visible at 1:24,000 were removed. The individual digital maps at 1:24,000 were used to create the regional 1:100, 000-scale map in ARC/INFO, and the features that were too small in area or so dense in number and location, were removed from the database to simplify the map.

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

Access_Constraints: none
Use_Constraints:
Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:100,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:100,000 will not yield greater real detail, although it may reveal fine- scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

  1. Who distributes the data set?[Distributor contact information not provided.]

  3. What legal disclaimers am I supposed to read?
