Description:
Abstract:
The digital geologic map of the east slope of Iron Mountain, Sweet Grass County, Montana was prepared from preliminary digital datasets digitized by Optronics Specialty Co., Inc. from a paper copy of plate 10 from UGSG Bulletin 1015-D (Howland, 1955).The files were prepared and transformed to the Montana State Plane South projection by Helen Z. Kayser (Information Systems Support, Inc.). Further editing and attributing was performed by Lorre A. Moyer in 2001. The resulting spatial digital database can be queried in many ways to produce a variety of derivative geologic maps.
Purpose:
This dataset was developed to provide a geologic map GIS of the east slope of Iron Mountain, Sweet Grass County, Montana for use in future spatial analysis by a variety of users. 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 1:3077 (for example, 1:2000 or 1:1500).
Supplemental_Information:
This GIS consists of two major ArcInfo datasets: one line and polygon file (ironmtn) containing geologic contacts and structures (lines) and geologic map rock units (polygons), and one point file (ironmtnp) containing structural data.

Data_Set_Credit:
In 2000, the U.S. Geological Survey contracted Optronics Specialty Co., Inc. (Northridge, CA) to scan and vectorize the geologic map of the east slope of Iron Mountain (Howland, 1955, plate 10). Helen Z. Kayser (contractor) transformed the GIS provided by Optronics from scanner inches to a state plane coordinate system (Montana South). Lorre A. Moyer then edited and attributed the spatial digital data files with an interim geologic data model in 2001.
Native_Data_Set_Environment:
SunOS, 5.7, sun4u UNIX, and Windows NT 4.0 PC Workstation ARC/INFO version 8.0
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy was verified by manual comparison of the source with hard copy printouts, plots, and on-screen evaluation.
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 area 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 Montana State Plane zone 4526.
Completeness_Report:
All geologic units from Howland (1955, plate 10) are included in this GIS.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal position accuracy for the digital data is no better than 15 feet based on the digitizing RMS error.
