Description:
Abstract:
This report provides a digital version of the Geologic map of the Stillwater Complex, Montana originally published by N. Page and W. Nokleberg (1974). Paper copies of the four geologic map sheets from the original report were scanned and initially attributed by Optronics Specialty Company (Northridge, CA) and remitted to the U.S. Geological Survey for further attribution and publication of the geospatial digital files. The resulting digital geologic dataset can be queried in a geographic information system (GIS) in many ways to produce a variety of geological maps.
Purpose:
This dataset was developed to provide a spatial database of the 1:12,000 scale geologic map of the Stillwater Complex for use in future spatial analysis. These data can be printed in a variety of ways to display various geologic features or used for digital analysis and modeling. This database is not meant to be used or displayed at any scale larger than 1:12000. The digital geologic map graphics and plot files (i797.gra/ps and i797-map.pdf) that are provided in the digital package are representations of the digital database. They are not designed to be cartographic products.
Supplemental_Information:
This GIS dataset consists of two Arc/Info datasets. The first is a line and polygon file (i797) containing geologic contacts and structures (lines) and geologic map rock units (polygons). A second file contains structural point data (i797p). Since the topographic base map for the original publication is no longer readily available, a georeferenced image (tiff) of the original basemap is also included.

Data_Set_Credit:
Optronics Specialty Company scanned the four geologic map sheets of Page and Nokleberg (1974) and provided minimally attributed ArcInfo interchange-format files to the USGS.
Helen Z. Kayser (contractor) registered and transformed to the datasets to the Montana state plane coordinate system.
Robert Miller combined the 8 individual sheet files into the two theme (geology and structural data) datasets, attached and attributed an interim geologic map data model; and visually compared the hard copy plots with the source documents.
Native_Data_Set_Environment:
Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 2; ESRI ArcCatalog 8.1.0.642
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribute accuracy was verified by manual comparison of the source with hard copy printouts, plots, and on-screen evaluation. Further digital review was performed as part of the USGS publication process. This included automated searching for missing or incorrect attributes.
Logical_Consistency_Report:
Polygon and chain-node topology present. 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. All nodes are represented by a single coordinate pair, which indicates the beginning or end of a line segment.
Completeness_Report:
All geologic units were compiled from Page and Nokleberg (1974) at a scale of 1:12,000.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal position accuracy for the digital data is no better than +/- 18 feet for the east half of map (sheet 1 and 2 of original publication) and +/- 8 feet for western half ( sheets 3 and 4 of the original) based on the digitizing root mean square (RMS) error. The geologic mapping was compiled on a topographic basemap map made for the project. This basemap locally differs from modern 1:24,000 topographic maps of the area, and thus geologic linework may locally appear mislocated when viewed with other than the original publication basemap.
The individual scanned images of parts of the basemap typically had an RMS error of approximately 3 meters. However, where parts of the georeferenced scans overlap, local shifts of up 15 meters were noted..

Process_Description:
The digital files were registered and transformed to state plane coordinate system by Helen Z. Kayser (contractor) at the USGS Spokane Field Office. R Miller combined the datasets and applied an interim geologic map data model. The data were then checked for position and attribute accuracy by comparing plots of the digital data to the source maps.
Process_Date: 2001
Process_Step:
Process_Description:
Low resolution scans (100 dpi) of portions of the basemap were georeferenced and converted to Arc/Info grids. The grids were clipped and merged into a single file then saved in a TIFF format.
