- Abstract:
-
This digital publication contains all the information used to publish U.S. Geological Survey Geologic Investigations Series I-2723 (Christiansen and others, 2002). The map shows the distribution and relationships of volcanic and surficial-sedimentary deposits in an area of Lassen Volcanic National Park and vicinity. Emphasis is on products of the 1914-1917 eruptions of Lassen Peak and the approximately 1000-year-old eruptions of Chaos Crags.
- Purpose:
-
This database was constructed in order to produce a geologic map as a basis for understanding processes involved in the explosive eruptions of Lassen Peak and Chaos Crags and for producing a volcano-hazards assessment of the Lassen Peak area.

This digital publication contains all the information used to publish U.S. Geological Survey Geologic Investigations Series I-2723 (Christiansen and others, 2002). The map shows the distribution and relationships of volcanic and surficial-sedimentary deposits in an area of Lassen Volcanic National Park and vicinity. Emphasis is on products of the 1914-1917 eruptions of Lassen Peak and the approximately 1000-year-old eruptions of Chaos Crags. The scale of the source map limits the spatial resolution (scale) of the database to 1:24,000 or smaller except in the area of a 1:2,500 inset map of the Lassen Peak summit area. The content and character of the digital publication, as well as methods for obtaining the digital files, are described here.
The database was compiled in ArcInfo, a commercial Geographic Information System (GIS) by Environmental Systems Research Institute (ESRI) of Redlands, California, using version 7.1.2 of ArcInfo for Unix with version 3.1 of the menu interface Alacarte (Fitzgibbon and Wentworth, 1991; Fitzgibbon, 1991; Wentworth and Fitzgibbon, 1991). The database files are in either COVERAGE (ArcInfo vector data) format or GRID (ArcInfo raster data) format. Coverages are stored in uncompressed Arc Export Format.

-
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 1:24,000 (except in the area of a 1:2,500 inset map of the Lassen Peak summit area) means that higher resolution information is not present in the dataset (except in the area of the 1:2,500 inset map). Plotting at scales larger than these will not yield greater real 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. Acknowlegdement of the U.S. Geological Survey would be appreciated in products derived from these data.

The database was compiled mainly in 1996-1997 from original geologic mapping by R. L. Christiansen, M. A. Clynne, and L. J. P. Muffler (Christiansen and others, 2002). A great deal of help was provided by Tracey J. Felger during preparation of the database. She established the fundamental formats and protocols for data entry and wrote most of the ArcInfo AMLs used to manipulate the database. David W. Ramsey and Joel Robinson provided much assistance during final stages of database compilation and preparation of the metadata.

-
- Attribute_Accuracy_Value: See Attribute_Accuracy_Explanation
- Attribute_Accuracy_Explanation:
-
Attribute accuracy is described, where present, with each attribute that is defined in the relevant Attribute_Domain_Values.
- Logical_Consistency_Report:
-
Polygon and arc (chain-node) topology present in ArcInfo coverage geo; other coverages are point or annotation; neither they nor the raster grids require topologic relationships.
- Completeness_Report:
-
The report is intended to describe completely the igneous and volcanic products, volcanic vent locations, and structural features at 1:24,000 scale (except in the area of a 1:2,500 inset map of the Lassen Peak summit area). Geological information mappable only at larger scales has been omitted.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
Well located data items are intended to have a horizontal positional accuracy better than 0.5 mm at 1:24,000 scale, or within 12 meters on the ground. The general positional accuracy of each line in the database is indicated qualitatively within the LTYPE field in the Arc Attribute Table (see Attribute_Domain_Values). Points in the database are generally well located. The position of each data item is derived from a USGS 1:24,000 topographic base map, and therefore additional inaccuracies may also be encountered that are within National Map Accuracy Standards.

Geologic linework was scanned and converted to a georeferenced grid. Lines were digitized by hand as vectors and edited on-screen. Polygon and region topology were created; each line, polygon, and region was tagged on-screen. Plotfiles were created in ArcPlot.

In areas other than the area of the large-scale summit map, each area polygon is assigned individually to a REGION.GENERAL subclass and has a PTYPE identical to the polygon PTYPE. In the summit area, however, the subclass REGION.GENERAL is assigned in some instances to larger areas that include polygons too small to show adequately at the scale of the main map.

- Entity_and_Attribute_Overview:
-
Lines (arcs) are recorded as chains of vectors and are described in an arc attribute table (AAT). They define the boundaries of the map units and other delineated areas as well as linear map features such as, faults, crater rims, and moraine crests. These distinctions, including geologic characterizations of the linear features, are recorded in the LTYPE field of the AAT. Map units (polygons) are described in a polygon attribute table (PAT). The identities of the map units from compilation sources are recorded in the PTYPE field of the PAT by map label. Note that ArcInfo coverages cannot contain both point and polygon topology, so only coverages with polygon information will have a polygon attribute table, and these coverages will not have a point attribute table. Files containing point features are described in a point attributed table (also PAT); examples of point features are sample or field-note locations, volcanic vents, etc. The REGION function of ArcInfo was used to delineate two types of larger areas in the database in addition to the polygons that represent the individual areas of each geologic map unit.
