Description:

Abstract:: The geology of the Payette National Forest and vicinity, Idaho was mapped and compiled by Karen Lund between 1992 and 1996. The geology was compiled onto 1:100,000-scale topographic base maps for input into a geographic information system (GIS). The digital geologic map database can be queried in many ways to produce a variety of geologic maps.
Purpose:: This dataset was developed to provide geologic map GIS of the Payette National Forest 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 1:100,000 (e.g., 1:62,500 or 1:24,000).
Supplemental_Information:: This GIS consists of four major Arc/Info GIS datasets: one line and polygon file (pnf100k) containing geologic contacts and structures (lines) and geologic map rock units (polygons), two point files (pnfpnt1 and pnfpnt2) containing structural data, and one polygon file (pnfshear) containing shear zone polygons.

Data_Set_Credit:

Karen Lund (USGS) mapped and compiled 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, transformed them to UTM zone 11 (with a y-shift) and attached and attributed an interim geologic map data model; Jon R. Oblad (Eastern Washington University) annotated the point data for output at a scale of 1:100,000.

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.

Completeness_Report:

Geologic map units were both compiled from a variety of maps (with map scales ranging from 1:24,000 to 1:250,000 and 1 inch equals 10 miles) and mapped in the field at a scale of 1:24,000. This data was compiled at a scale of 1:100,000. 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 RMS error resulting from the four file transformations ranged from 19 to 20 meters, thus the overall accuracy of the digital geologic map is no better than +/- 20 meters. It was tested by visual comparison of the source with hard-copy plots.

Source_Contribution:

Karen Lund mapped and compiled the geology of the Payette National Forest and vicinity, Idaho between 1992 and 1996. The other three authors were responsible for creating the digital product.

Process_Step:

Process_Description:: Clear film positives of the 1:100,000-scale geologic map compilation were electronically scanned to create raster images, converted to vector, polygon and point GIS layers, and minimally attributed by a contractor (Optronics Specialty Co., Inc., Northridge, CA). The USGS also provided the contractor with the linework for the Snake River which had been converted from digital line graph (DLG) format files (US Geological Survey, 1993) to Arc/Info GIS so as to delineate discrete geologic unit boundaries along the western margin of the map area. The initial products were remitted to the USGS in an Arc/Info EXPORT format in scanner units and with latitude and longitude registration tics digitized from the original film positives. These tic points were used to convert (or transform) the digital files to calculated latitude-longitude points for a Universal Transverse Mercator (zone 11, with a -5,000,000 meter y-offset or false northing) map projection. The digital files were then augmented with an interim geologic map data model (or data base), further attributed and edited, and then plotted and compared to the original film positives of the geologic map to check for digitizing and attributing errors.
