Franczyk, Ian P. Madin, Carlie J. M. Duda, and Jason D. McClaughry http://www.oregongeology.org/ This feature class contains map unit polygons that represent bedrock and surficial geologic units in Oregon. The attributes within this feature class are provided as a descriptive summary for each unit. This feature class does not have any cartographic representations associated with its features. Polygons that record the distribution of map units on the particular map horizon. The polygons in this feature class are units of consolidated (solid) rock that underlie soils or other unconsolidated materials and unconsolidated earth materials such as soils and sediments. The purpose of this compilation is to create statewide geospatial datasets (e.g., map unit polygons, faults, and folds) from the best available published traditional geologic maps, to provide a consistent and maintainable structure for Oregon geologic map data, and to simplify data exchange amongst all users. 2020 Publication Complete None planned -124.808648 -116.418518 46.303260 41.926900 ISO 19115 Topic Category geoscientificinformation Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus geologic map geology geologic unit bedrock USGS Thesaurus geologic units bedrock geologic units surficial geologic units Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus North America United States of America Oregon Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus bedrock alluvium colluvium sediment 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 in the MapUnitPolys feature class in OGDC6. No attempt was made to resolve known errors and NULL entries that reside in the source data (i.e. Symbol and Notes attribute). 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; topology exceptions: 448, MapUnitPolys must not have gaps are the boundary for the state of Oregon. 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 historical sources and thereby is not complete. Not all existing attributes from OGDC-6 were applicable to this schema, and therefore were not included. 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.

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. References citations used for this compilation can be found in the DataSources table.
