Description:
Abstract:
This digital map database represents the general distribution of bedrock and surficial deposits of the Yosemite National Park vicinity. It was produced directly from the file used to create the print version in 1989. The Yosemite National Park region is comprised of portions of 15 7.5 minute quadrangles. The original publication of the map in 1989 included the map, described map units and provided correlations, as well as a geologic summary and references, all on the same sheet. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:125,000 or smaller.
Purpose:
The digitizing of this database is to provide access of a previously published map to the public via the web. This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:125,000) scale. The accompanying PDF is a scan of the previously published paper map, and is not intended as a cartographic product.
Supplemental_Information:
The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California), version 8.3. The files are in COVERAGE (ARC/INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 8.x). ARC/INFO export files (files with the .e00 extension) can be converted into ARC/INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems, such as MapInfo via ArcLink and ESRI's ArcView (version 1.0 for Windows 3.1 to 3.11 is available for free from ESRI's web site: ).
The digital compilation was originally done in Scitex RES280 cartographic system for print production. The Scitex raster digit files were tranferred into an Arc GIS system. The raster files were imported into coverages (polygon and line), using the Scitexpoly and Scitexline commands in command-line Arc. Scitex numeric font/color codes were converted from channel information to basic geologic units and geologic line types. Coordinate information was provided to the corners of the map, projection was maintained from print version.

Access_Constraints: none
Use_Constraints:
Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:125,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:125,000 will not yield greater detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
Any hardcopies utilizing these data shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent this data set, nor to imply the U.S. Geological Survey approved changes the user has made.

Overview_Description:
Entity_and_Attribute_Overview:
Lines (arcs) are recorded as strings of vectors and are described in an arc attribute table ("filename".AAT). They define the boundaries of the map units and other delineated areas as well as linear features such as but not limited to, faults, crater rims, and moraine crests. These distinctions, including geologic characterizations of linear features, are recorded in the LTYPE field in the AAT. Map units (polygons) are described in a polygon attribute table ("filename".PAT). The identities of the map units from compilations sources are recorded in the PTYPE field of the PAT by unit symbol. Almost all of the attributes in the various attribute tables included in the report are set or calculated by ArcInfo and include "filename"#, "filename"-ID, LENGTH, FNODE, TNODE, RPOLY, LPOLY, AREA, and PERIMETER. The rest are defined by the author as described above and include LTYPE, PTYPE.
