Oregon Geologic Data Compilation, release 7 (OGDC-7), compiled by Jon J. Franczyk, Ian P. Madin, Carlie J.M. Duda, and Jason D. McClaughry

Release 7 supersedes all previous releases of OGDC.

WHAT’S IN THIS PUBLICATION?
This Esri-format geodatabase integrates the best available published geologic mapping for the state by combining maps and data into a single consistent and maintainable digital database. This release of the geodatabase was migrated to the National Cooperative Geologic Mapping Program (NCGMP) Geologic Map Schema (GeMS).

Abstract
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.
