Identification Information
Title: Oregon Geologic Data Compilation
Originator: Compiled by Lina Ma, Ian P. Madin, Keith V. Olson, and Rudie J. Watzig, Oregon Department of Geology and Mineral Industries
Publication Date: 2009
Abstract: This data layer is an element of the Oregon GIS Framework. The Oregon Department of Geology and Mineral Industries (DOGAMI) has completed the six-year project to digitally compile geologic data for the entire state. This effort brings together the best available geologic mapping from state and federal agency sources, student thesis work, and consultants. The project will create a new statewide digitally-compiled geologic map coverage that will become a component of the Geoscience Theme within the Oregon Framework Themes. The Oregon Framework Themes effort is coordinated by the Oregon Geospatial Enterprise Office, Oregon Department of Administrative Services.
Purpose: To assemble the best available geologic map information for Oregon by integrating the work of many individual geologic mappers into a vector digital data set stored in geographic information system (GIS) format with links to a relational database.

Use: This geologic data compilation is not intended for site-specific investigations. This data set is the result of integrating parts or all of 345 separate reference maps, and the accuracy varies according to the original reference map scale (1:12,000 to 1:500,000). Data resolution greater than original reference map scale(s) is not available.DOGAMI makes no warranty as to the currency, completeness, accuracy or utility of any specific data. This disclaimer applies both to individual use of the data and aggregate use with other data. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data.User should use caution when overlaying other data sets and should not make legally binding decisions from this data. Any person using the information presented here should fully understand the data collection and compilation process before beginning their analysis/use. The burden of determining fitness for use lies with the user.To avoid the risk of misinterpretation, invalid results, and erroneous conclusions, the users must consider original map scale, collection methodology, and any other conditions specific to every data element and each dataset as a whole. Potential users are advised to consult with DOGAMI to gain an understanding of the inherent limitations of this data set and its scope of inference. Also, the user must be aware that errors and conditions originating from physical sources involved in developing a dataset may be reflected in the data, and that the digital processing performed during preparation, storage, and transmission of the dataset may have exacerbated such errors and/or introduced additional ones.
