Miller, R.F. Burmester, D.M. Miller, and R.E. Powell between 1963 and 1995 onto a scale-stable 1:250,000 topographic map base and subsequently input into an Arc/Info geographic information system (GIS) by P.D. Derkey. 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 Sandpoint 1:250,000 quadrangle for use in 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 consists of one major Arc/Info dataset: a line and polygon file (sand250k) containing geologic contacts and structures (lines) and geologic map rock units (polygons and lines).

Any hardcopies utilizing this data set shall clearly indicate its 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.

Miller, R.F. Burmester, D.M. Miller and R.E. Powell mapped the geology onto stable-base material; Optronics Specialty Co., Inc. scanned the geologic map and provided minimally attributed Arc/Info interchange-format files to the USGS; Pamela D. Derkey (USGS) imported the files in Arc/Info, transformed them to UTM zone 11 (with a y-shift) and attached and attributed an interim geologic map data model. Native_Data_Set_Environment: SunOS, 5.5.1, sun4u UNIX ARC/INFO version 7.1.1 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 duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The neatline was generated by mathematically generating the four sides of the quadrangle, densifying the lines of latitude and projecting the file to UTM zone 11 (with a y-shift). Completeness_Report: All geologic units were mapped in the field at scales ranging from 1:24,000 to 1:62,500 and compiled at a scale of 1:250,000. In general, the minimum mapping unit is from 1 to 3 acres. Some small units and those obscured by dense forest cover may not be included in this dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy for the digital data is no better than +/- 24 meters based on the transformation RMS error. It was tested by visual comparison of the source with hard copy plots. Lineage: Process_Step: Process_Description: Geologic map information was compiled from field sheets on to a stable-base copy of the USGS Sandpoint 1:250,000-scale topographic quadrangle map and manually labeled. Process_Description: Stable-base map was scanned and converted from a raster to a vector format (in scanner units). Process_Description: Digital files were transformed to UTM zone 11 (meters), with a RMS error (input,output) = (0.004, 24.177), and attributed using an interim geologic map data model. The data were checked for position by comparing plots of the digital data to the source.
