Description: Abstract: This dataset was digitized by the U.S. Geological Survey EROS Data Center and U.S. Geological Survey Spokane Field Office for input into an Arc/Info geographic information systsem (GIS). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps. Purpose: This dataset was developed to provide geologic map GIS of the Kalispell 1:250,000 quadrangle for use in the future spatial analysis by a variety of users. This database is not meant to be used or displayed at any scale larger than 1:250,000 (e.g., 1:100,000 or 1:24,000). Supplemental_Information: This GIS dataset consists of one major Arc/Info dataset: a line and polygon file (kal250k) that contains geologic contacts and structures (lines) and geologic map rock units (polygons).

Any hardcopies utilizing these data sets 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 these data sets, nor to imply that changes they made were approved by the U.S. Geological Survey.

Harrison, Earle R. Cressman, James W. Whipple compiled the geology and published the original geologic paper map. EROS Data Center staff scanned/digitized geologic map and prepared the original ArcInfo data prior to 1994. Montana Bureau Mines and Geology acquired the original data and, in 1999, provided it to the USGS in Spokane, WA. R.J. Miller (USGS) converted the original data to a single topologically correct ArcInfo coverage. Helen Z. Kayser (contractor) attached and attributed an interim geologic map data model. Thomas P. Frost (USGS), Pamela D. Derkey (USGS), and William N. Kelley (contractor) visually compared the hard copy plots with the source documents; Native_Data_Set_Environment: SunOS, 5.7, sun4u UNIX ARC/INFO version 7.2.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attribute accuracy was verified by manual comparison of the source with hard copy printouts and plots. Logical_Consistency_Report: Polygon and chain-node topology present. Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end to end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor do duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. Completeness_Report: This digital geologic map is wholly derived from Harrison, and others (1992).
