Franczyk, Ian P. Madin, Carlie J. M. Duda, and Jason D. McClaughry http://www.oregongeology.org/ This feature class identifies structural folds, lineaments, joints, and dikes located within Oregon. Features within this dataset are represented as vector lines. The vector line shows the approximate location and the angle down from horizontal of the plane that bisects the fold, as well as the general angle that the layers of rock dip away from that plane. This geodatabase contains cartographic representations for line symbols from Section 5 of FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC Document Number FGDC-STD-013-2006) The folds in this feature class represent the location, extent, and surface expression within Oregon where rocks have been compressed and folded. 2020 Publication Complete None planned -124.750095 -116.458573 46.213150 41.946999 ISO 19115 Topic Category geoscientificinformation Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus geologic map geology syncline anticline Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus North America United States of America Oregon Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus None MAP DATA: This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.

Oregon Department of Geology and Mineral Industries jpeg image (.jpg) Supported for release 7 by the Oregon Geospatial Enterprise Office, Framework Development Program. Unclassified Attributes for existing data were copied from the source data Folds feature class in OGDC6. No attempt was made to resolve known errors and NULL entries that reside in the source data. Attribute accuracy of the database was visually inspected but despite the checks there may be some attributes that are still mislabeled. Topology has been validated for this feature class, as defined by the USGS GeMS schema document GeMSv2_draft7g_ProvisionalRelease.pdf. Topology errors: 0. Tests for logical consistency were performed by ArcGIS Topology software. All points, lines, and polygons were visually checked, and are labelled correctly. Data collection does not include all possible historic sources and thereby is not complete. However all data available from OGDC-6 has been included. Not all features have an assigned RuleID and its associated cartographic representation, and therefor are not symbolized correctly. The source data, OGDC-6, used many different sources variable in age and scale in its compilation. Therefore it has a highly variable horizontal positional accuracy throughout the state of Oregon. Refer to the original source data for positional accuracy, citations for data sources are listed in the DataSources table.

References citations used for this compilation can be found in the DataSources table. The following topology checks were performed on the Contacts, Faults, and MapUnitPoly feature classes in the OGDC_v6.gdb. The following topology rules using Esri ArcGIS 10.6 for desktop were used. Rule 1: MapUnitPolys must not have gaps. Rule 2: MapUnitPolys must not overlap. Rule 3: Contacts must not overlap. Rule 4: Contacts must not have dangles. Rule 5: Contacts must not self-overlap. Rule 6: Contacts must not self-intersect. Rule 7: Faults must not overlap with (contacts). Rule 8: Faults must not self-overlap. Rule 9: Faults must not self-intersect. Rule 10: Faults must not have dangles. Rule 11: Faults must be single part. Rule 12: Folds must not self-intersect. Rule 13: Folds must not self-overlap.

NCGMP09 v1.1 GeologicLines_ID Primary key. Values= GEL1, GEL2, GEL3, etc. Null values not permitted. NCGMP09 v1.1 Type Classifier that specifies what kind of geologic feature is represented by a database element for example, anticline, syncline, monocline, etc. NCGMP09 v1.1 IsConcealed This is a flag for lines covered by an overlying map unit. Y= Yes is concealed N= Is not concealed NCGMP09 v1.1 ExistenceConfidence Expresses whether or not the observations and data support the continuity or existence of a geologic feature. FGDC-STD-013-2006 IdentityConfidence Expresses whether or not the observations and data support the stated nature, origin, or geometry of a mapped geologic feature.
