Oregon Geologic Data Compilation - 2015
Oregon Department of Geology and Mineral Industries
This data layer is an element of the Oregon GIS Framework. The Oregon Geologic Data Compilation (OGDC) Release 6 is a statewide compilation of geologic data created by the Oregon Department of Geology and Mineral Industries (DOGAMI).OGDC-6 is a personal geodatabase (GIS data) and is comprised of a feature dataset and relationship tables as follows:GEODATABASE Feature dataset: Geology_FC datasetThe following Feature Classes contain data: Bedding, Contacts, Faults, Folds, Foliation, JointsAndLineaments, MapUnitPolys, REF_MAP, and VolcanicLineFeatures. Feature Classes without data are as follows: Cleavage, GlacialAndSurficialLines, GlacialAndSurficialPoints, LandslideMWLineFeatures, LandslideMWPointFeatures, ObservationOrnamentations_Contacts, ObservationOrnamentations_Faults, ObservationOrnamentations_Joints, SmallMinorFolds, SmallMinorJoints, and VolcanicPointFeatures.GEODATABASE Relationships:Tables: tblAge, tblEnvironment, tblFGDC_Lookup, tblMapSubUnit, tblMapSubUnitColors, tblMapSubUnitHandSampleTexture, tblMapSubUnitLithologyMineralComp, tblMapSubUnitOutcropMajorStructures, tblMapUnit, TblRefBaseMap, TblRefConversionInfo, TblRefGeologicInfo, tblStratigraphic, and tblThickness.
The purpose of the compilation is to integrate and make available the best known geologic mapping for the state by combining maps and data into a single digital database. Sources of geologic mapping include state and federal agencies, student thesis work, and consultants. This sixth release of OGDC (OGDC-6) builds directly from data published in OGDC-5, but is driven by significant new mapping projects published in the five years since the 2009 release as well as a major format change to the data.
