This is a nonspatial table that captures the content of the Description of Map Units (DMU) included in a geologic map report.
This table in the GeMS file geodatabase captures the content of the Description of Map Units (DMU), or equivalent to the List of Map Units and associated plate text, included in the geologic map. This is a nonspatial table that captures the content of the Description of Map Units (DMU) included in a geologic map report.
The purpose of this GeMS file geodatabase is the storage and management of the geospatial data of the geologic information in the Athena 1:24,000-scale quadrangle, Umatilla County. This file geodatabase was compiled to construct a geologic map of the Athena 1:24,000-scale quadrangle, Umatilla County, Oregon, and it is this map that is a deliverable for U.S. Geological Survey STATEMAP program. This is a GeMS file geodatabase with cartographic representation and the central storage location for features and associated tables. The features and tables contain 1:24,000-scale geologic map data of Athena 7.5′ quadrangle, Umatilla County, Oregon. At the core of this product is the U.S. Geological Survey Geologic Map Schema (GeMS) file geodatabase incorporating FGDC standard schema for digital geologic map data. The storage location for features is GeologicMap dataset and with additional attributes in associated tables.

Geologic mapping was supported in part between 2021 and 2022 by grants from the STATEMAP [http://ncgmp.usgs.gov/about/statemap.html]component of the U.S. Geological Survey (USGS) National Cooperative Geologic Mapping Program under cooperative agreement G21AC00647. Additional funds were provided by the State of Oregon through the Oregon Department of Geology and Mineral Industries.
Care was taken to limit categorical attribute errors. Attribute accuracy of the database was visually inspected but despite the checks there may be some attributes that are still mislabeled.
Attribute fidelity is tested by visual comparison of the pamphlet description with the records in the table. Characterization of general lithology of units were assessed based on the general lithology confidence. See U.S. Geological Survey, Geologic Map Schema, 2020 for more information.
The table only includes information collected in the study area. Data collection does not include all possible traverses, measured sections, etc., and thereby is not complete. Not all field data were collected nor were all of the data compiled from lineage maps. Geologic concepts and definitions of map units are current. Density of observations is sufficient to support the map(s).
The geodatabase was validated by, employing the Validate script provided in the GeMS Tools for Arc10.5 version 1.6.14. This checks that units are unique in the DescriptionOfMapUnits table, they cross reference between datasets in the geodatabase, and have at least one match with the exception of units outside the project area yet still hold value to the project area. Lineage maps were used as base maps in the following manner: 1) to compare the mapping against previous work; 2) scribing geologic features, e.g., bedding, faults, and folds; and 3) reference materials.
