National Park Service Geologic Resources Inventory (GRI) program, 20150930, Metadata for the Unpublished Digital Bedrock Geologic Map of Obed Wild and Scenic River and Vicinity, Tennessee (NPS, GRD, GRI, OBED, OBED digital map).Online Links:
Feature and table attribution was derived and checked with the source map(s). Attribution was checked (QCd) for errors. Users of this data are advised to FULLY and CAREFULLY READ the "DISTRIBUTION LIABILITY" section of this metadata before using the data.
Data was produced from digital source data and a georeferenced source map TIF image(s) (300dpi). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale and United States National Map Accuracy Standards features are within (horizontally) 12.2 meters or 40 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they portrayed are in Google Earth, ArcGIS or other software used to display this dataset. The PRECISION of any Shapefile (SHP) files is DOUBLE. The maximum root mean square (RMS) horizontal accuracy of the georeferenced images as measured in ArcMap is 1.1 meters. Coordinate tics on the georeferenced (registered and rectified) source map image(s) was checked against control points that had the exact specified coordinates of the tic. The direct distance between the image tic and its control point were measured. All measured distances were less than 50% of the required distance to meet National Map Accuracy Standards (1/50th of an inch for maps at 1:20,000 scale and smaller). Features was checked (QCd) after digitizing for positional accuracy errors using the georeferenced source map image.
No vertical coordinates are present in this GRI digital dataset.
All data is considered complete to the extent of the source map(s).
GIS data in 10.1 file geodatabase and 2.2 KML/KMZ file formats.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- Not for use at scale greater than 1:24,000 (source map scale). Users of this data are cautioned about the locational accuracy of features within this dataset.
