Introduction

The geology of the Thompson Falls 1:100,000 quadrangle, Idaho was compiled by

Reed S. Lewis in 1997 onto a 1:100,000-scale greenline mylar of the topographic base

map for input into a geographic information system (GIS). The resulting digital geologic

map GIS can be queried in many ways to produce a variety of geologic maps. Digital

base map data files (topography, roads, towns, rivers and lakes, etc.) are not included:

they may be obtained from a variety of commercial and government sources. 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).

The map area is located in north Idaho (Fig. 1). This open-file report describes the

geologic map units, the methods used to convert the geologic map data into a digital

format, the Arc/Info GIS file structures and relationships, and explains how to download

the digital files from the U.S. Geological Survey public access World Wide Web site on

the Internet.

We thank Steve Box, Tom Frost, and Brian White for their technical reviews and

Nancy Shock for a digital review.

Description of Map Units

The geologic map was compiled primarily from Griggs (unpublished field maps dated

1961-1969, 1973), Harrison and others (1986), Hobbs and others (1965), Hosterman

(1956) and Ransome and Calkins (1908) (see Fig. 2, areas 1-6). Additional map sources

used were Gibson and others (1941), Schalck (1989), Shenon (1938), Umpleby and Jones

(1923), and B.G. White (written commun., 1997) (see Fig. 2, areas A-E).

Qa ALLUVIAL DEPOSITS (HOLOCENE)--Stream deposits in modern drainages.

Qg GLACIAL DEPOSITS (QUATERNARY)--Poorly sorted and poorly stratified,

unconsolidated deposits principally of glacial origin. Includes till in lateral and

ground moraines as well as outwash and minor modern stream alluvium.

Tsm SEDIMENT (MIOCENE)--Unconsolidated, poorly sorted, fluvial sediment 70 to

330 m above the present stream levels. Ranges in size from clay to boulders and is

derived from local sources (Hosterman, 1956).

Kms MONZONITE AND SYENITE (CRETACEOUS)--Small stocks of hornblende

monzonite, porphyritic hornblende monzonite, alkali-feldspar syenite, and

pyroxene syenite (Schlack, 1989). Age determinations have yielded conflicting

dates, but emplacement ages of about 100 Ma are likely (Marvin and others, 1984;

Schlack, 1989).

Ysp STRIPED PEAK FORMATION (MIDDLE PROTEROZOIC)--Interbedded

quartzite and argillite with some arenaceous dolomitic beds; usually thinly bedded

(Hobbs and others, 1965). Colors range from purplish gray and very pale pink to

gray and green. Mud cracks and ripple marks common.

Ywu WALLACE FORMATION, UPPER MEMBER (MIDDLE PROTEROZOIC)--

Predominantly thinly laminated medium- to dark-gray argillite; some interbedded

light-gray quartzite and arenaceous dolomite (Hobbs and others, 1965).

Ywml WALLACE FORMATION, MIDDLE AND LOWER MEMBERS, UNDIVIDED

(MIDDLE PROTEROZOIC)--Light-gray dolomitic and calcareous quartzite

interbedded with medium- to dark-gray argillite (Hobbs and others, 1965). Some

impure dolomite beds near top. Ripple marks, small scale crossbedding, and

molar-tooth and ovoid structures in some layers. Mapped asYwl by Hobbs and

others (1965).

quartzite and argillite that comprise bulk of formation (Hobbs and others, 1965).

Characteristically thin bedded and many layers laminated. Predominantly purplish

red and grayish red; argillite is darker. Some carbonate-bearing beds, mostly in

upper part. Ripple marks, mud cracks, and mud-chip breccia in some layers.

Yr REVETT FORMATION (MIDDLE PROTEROZOIC)--Thick-bedded white to

light-gray quartzite containing interbedded impure and nearly pure quartzite in

upper and lower parts, and a few widely spaced argillite partings (Hobbs and

others, 1965). Crossbedded and laminated in part.

Ybk BURKE FORMATION (MIDDLE PROTEROZOIC)--Light- to greenish-gray

fine-grained impure quartzite with lesser amounts of nearly white to light-gray

nearly pure to pure quartzite (Hobbs and others, 1965). Beds predominantly 5 to

20 cm thick. Ripple marks and pseudoconglomerate are common.

Ypu PRICHARD FORMATION, UPPER MEMBER (MIDDLE PROTEROZOIC)--

Light-gray to nearly white pure to impure quartzite interbedded with laminated

argillite (Hobbs and others, 1965). Quartzite beds 5 to 45 cm thick. Ripple marks

and graded bedding are common.

Ypl PRICHARD FORMATION, LOWER MEMBER (MIDDLE PROTEROZOIC)--

Banded dark-gray argillite, laminated in part; weathers rusty red (Hosterman,

1956).

Data Sources, Processing, and Accuracy

Lewis’ greenline mylar inked with the geologic data was electronically scanned to

create a raster digital image, converted to vector, polygon and point GIS layers, and

minimally attributed by a contractor (Optronics Specialty Co., Inc., Northridge, CA). This

initial product, with latitude and longitude registration tics digitized from the scanned

image, was remitted to the U.S. Geological Survey in an Arc/Info EXPORT format in

scanner units. The tic points were used to transform the digital files to calculated latitudelongitude points for a Universal Transverse Mercator (zone 11, with a -5,000,000 m yoffset) map projection. The RMS errors1

 resulting from the file transformations were

small (7.350 meters, see Appendix A). 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 greenline mylar of the geologic map to check for

digitizing and attributing errors. All processing by the U.S. Geological Survey was done

in Arc/Info version 7.1.1 installed on a Sun Ultra workstation.

The overall accuracy (with respect to the location of lines and points) of the digital

geologic map (see Figs. 3 and 4 for pagesize versions) is probably no better than +/- 7

meters. This digital 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).

 

1

 The root mean square error (RMS error) describes the deviation between the tic locations in the input

file and those in the output file. It is an indication of the quality of the derived transformation and is a

measure of the quality of the original scanned materials. The transformation report of errors for each tic

point is given in Appendix A.

Obtaining Digital Data

The complete digital version of the geologic map is available in Arc/Info interchange

(or 'EXPORT') format with associated data files. These data and map images are

maintained in a Universal Transverse Mercator (UTM) map projection:

Projection: UTM

Zone: 11

Y-offset (false northing): -5,000,000 meters

Units: meters

To obtain copies of the digital data, do one of the following:

1. Download the digital files from the USGS public access World Wide Web site on the

Internet: URL = http://wrgis.wr.usgs.gov/open-file/of99-438/

or

2. Anonymous FTP from wrgis.wr.usgs.gov, in the directory

pub/open-file/of99-438/

The Internet sites contain the digital geologic map of part of the Thompson Falls 1:100,000

quadrangle, Idaho both in Arc/Info interchange-format files (tf100k.e00 and tf100k.e00) and 

as an HPGL2 plot file (tf100k.hp) of the map area, as well as the associated data files and

Arc/Info macro program which is used to plot the map at a scale of 1:100,000.

To manipulate this data in a geographic information system (GIS), you must have a

GIS that is capable of reading Arc/Info interchange-format files.

Obtaining Paper Maps

Paper copies of the digital geologic map are not available from the USGS. However,

with access to the Internet and access to a large-format color plotter that can interpret

HPGL2 (Hewlett-Packard Graphics Language), a 1:100,000-scale paper copy of the map

can be made, as follows:

1. Download the plot file of the map, tf100k.hp, from the USGS public access World

Wide Web site on the Internet using the

URL = http://wrgis.wr.usgs.gov/open-file/of99-438

or

2. Anonymous FTP the plot file, tf100k.hp, from: wrgis.wr.usgs.gov, in the directory:

pub/open-file/of99-438/

3. This file can be plotted by any large-format color plotter that can interpret HPGL2.

The finished plot is about 29 inches by 39 inches.

Paper copies of the map can also be created by obtaining the digital files as described

above and then creating a plot file in a GIS, using the Arc/Info macro language (AML)

program, tf100k.aml, included in the data package.

Appendix A - Transformation report for Thompson Falls GIS

Three Arc/Info files were remitted to the USGS from the contractor. Each of the three

files had to be transformed to a UTM map projection (zone 11, y-shift = -5,000,000

meters). The errors for each latitude and longitude tic used in the transformation were the

same for each of the three transformed files and are given below. The report identifies a

root mean square (RMS) error of 7.350 meters.

 Description:

 Abstract:

 The geology of the Thompson Falls 1:100,000 quadrangle, Idaho was

 compiled by Reed S. Lewis in 1997 onto a 1:100,000-scale topographic

 base map for input into an Arc/Info geographic information system

 (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

 Idaho portion of the Thompson Falls 1:100,000 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 1:100,000 (e.g., 1:62,500 or 1:24,000).

 Supplemental_Information:

 This GIS consists of two major Arc/Info datasets: one line and

 polygon file (tf100k) containing geologic contacts and structures

 (lines) and geologic map rock units (polygons), and one point file

 (tfpnt) containing structural data.

 Data_Set_Credit:

 Reed S. Lewis (contractor) 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;

 Thomas P. Frost (USGS) visually compared the hard copy

 plots with the source;

 Jon R. Oblad (EWU) 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.

 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 compiled from previously existing

 geologic maps ranging in scale from 1:24,000 to 1:250,000.

 Positional_Accuracy:

 Horizontal_Positional_Accuracy:

 Horizontal_Positional_Accuracy_Report:

 The horizontal positional accuracy for the digital data is no

 better than +/- 7 meters based on the transformation RMS error.

 It was tested by visual comparison of the source with hard copy

 plots.

 Source_Contribution:

 This secondary source provided additional information

 in compiling the geologic map.

 Process_Step:

 Process_Description:

 Geologic map information from source maps were reduced to a

 scale of 1:100,000 using a copy machine, then manually compiled

 onto a stable-base copy of the USGS 1:100,000-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) = (0.003, 7.350), 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.

 Overview_Description:

 Entity_and_Attribute_Overview:

 The 'Digital geologic map of part of the Thompson Falls 1:100,000

 quadrangle, Idaho' Open-File Report 99-438 contains a detailed

 description of each attribute code and a reference to the

 associated map symbols on the map source materials.

 The GIS includes a geologic linework arc attribute table,

 tf100k.aat, that relates to the tf100k.con (contact look-up

 table), tf100k.str (structure look-up table), and tf100k.ref

 (source reference look-up table) files; a rock unit polygon

 attribute table, tf100k.pat, that relates to the tf100k.ru

 (rock unit look-up table) and tf100k.ref (source reference

 look-up table) files; and a geologic map symbol point

 attribute table, tfpnt.pat, that relates to the tfpnt.sym

 (structural point data look-up tables) and tfpnt.ref (source

 reference look-up table) files.
