Title: Spatial digital database for the geologic map of Oregon
Geospatial_Data_Presentation_Form: vector digital data
Series_Name: U.S. Geological Survey Open-File Report
Publication_Place: Menlo Park, California
Publisher: U.S. Geological Survey
This report publishes a geologic digital spatial database (ORGEO) for the geologic map of Oregon by Walker and MacLeod (1991) which was originally printed on a single sheet of paper at a scale of 1:500,000 and accompanied by a second sheet for map unit descriptions and ancillary data. The spatial digital database (GIS) provided in this report supersedes an earlier digital edition by Raines and others (1996).
This report is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic process and mineral resource information for use in spatial analysis in a geographic information system (GIS). This database can be queried in many ways to produce a variety of geologic maps. This database is not meant to be used or displayed at any scale larger than 1:500,000 (for example, 1:100,000).
The digital geologic map of Oregon consists of a single coverage (ORGEO) which contains map units and lines. The feature attribute tables include a geologic linework table, ORGEO.AAT, that relates to the ORGEO.CON (contacts and boundaries), ORGEO.ST2 (structures), and ORGEO.REF (source reference) files, and a rock unit table, ORGEO.PAT, that relates to the ORGEO.RU (rock unit) and ORGEO.REF (source reference) files.

The National Mapping Division of the U.S. Geological Survey scanned and vectorized mylar compilation sheets and converted the files to ArcInfo; Gary L. Raines and Katherine A. Connors added a data model and additional attribute data for an initial digital edition (Raines and others, 1996) of the Walker and MacLeod (1991) geologic map of Oregon.
This second digital edition, prepared by Robert J. Miller, represents further revision of Raines and others' (1996) first edition.
