This dataset represents structural faults (at the scale of original mapping) and descriptive data and shows the location and type of faults in the state of Oregon. Oregon Geologic Data Compilation - 2009
This is a compressed file containing a File Geodatabase with multiple feature classes, metadata XML, and a PDF pamphlet.
The Oregon Geologic Data Compilation (OGDC) is a digital data collection of geologic studies created by the Oregon Department of Geology and Mineral Industries (DOGAMI). The purpose of the compilation is to integrate and make available the best available published geologic mapping for the state by combining maps and data into a single consistent and maintainable digital database. OGDC was first released by DOGAMI in 2004, with successive releases building either geographically or qualitatively on previous releases. OGDC-6 was published in 2015 and serves as the Oregon Geologic Data Standard for the state as a data element component of the Geosciences Theme within the Oregon Framework Themes. The release of OGDC-7 builds directly from data published in OGDC-6 by migrating the database structure to the National Cooperative Geologic Mapping Program (NCGMP) Geologic Map Schema (GeMS). DOGAMI has implemented the GeMS schema as the database standard for all geologic mapping projects published from 2019 onward to meet NCGMP requirements and to support the state’s contribution to standardized nationwide geologic content. The transition to OGDC-7 required migrating the existing OGDC statewide compilation to the GeMS format for streamlining future updates, data creation, and data maintenance. Additionally, the transition to GeMS adds fundamental geologic map point data (e.g., structural data, geochronology, and geochemistry) as comprehensive geospatial datasets not included as part of previous versions of OGDC.
The polygons in this feature class are geologic map units assigned a radon potential rank, based on three major geologic factors: geologic materials, aerial radiometric measurement averages, and indoor air radon measurement averages.
