Abstract:
This data set maps and describes the geology of the Chewelah 30' X 60' quadrangle, Washington and Idaho. Created using Environmental Systems Research Institute's ARC/INFO software, the data base consists of the following items: (1) a map coverage containing geologic contacts and units, (2) a point coverage containing site-specific geologic structural data, (3) two coverages derived from 1:100,000 Digital Line Graphs (DLG); one of which represents topographic data, and the other, cultural data, (4) two line coverages that contain cross-section lines and unit-label leaders, respectively, and (5) attribute tables for geologic units (polygons), contacts (arcs), and site-specific data (points). In addition, the data set includes the following graphic and text products: (1) A PostScript graphic plot-file containing the geologic map, topography, cultural data, and two cross sections, and on a separate sheet, a Correlation of Map Units (CMU) diagram, an abbreviated Description of Map Units (DMU), modal diagrams for granitic rocks, an index map, a regional geologic and structure map, and a key for point and line symbols; (2) PDF files of the Readme text-file and expanded Description of Map Units (DMU), and (3) this metadata file.
The geologic map database contains original U.S. Geological Survey data generated by detailed field observation and by interpretation of aerial photographs. The map was compiled from geologic maps of eight 1:48,000 15' quadrangle blocks, each of which was made by mosaicing and reducing the four constituent 7.5' quadrangles. These 15' quadrangle blocks were mapped chiefly at 1:24,000 scale, but the detail of the mapping was governed by the intention that it was to be compiled at 1:48,000 scale. The compilation at 1:100,000 scale entailed necessary simplification in some areas and combining of some geologic units. Overall, however, despite a greater than two times reduction in scale, most geologic detail found on the 1:48,000 maps is retained on the 1:100,000 map. Geologic contacts across boundaries of the eight constituent quadrangles required minor adjustments, but none significant at the final 1:100,000 scale.
The geologic map was compiled on a base-stable cronoflex copy of the Chewelah 30' X 60' topographic base and then scribed. The scribe guide was used to make a 0.007 mil-thick blackline clear-film, which was scanned at 1200 DPI by Optronics Specialty Company, Northridge, California. This image was converted to vector and polygon GIS layers and minimally attributed by Optronics Specialty Company. Minor hand-digitized additions were made at the USGS. Lines, points, and polygons were subsequently edited at the USGS by using standard ARC/INFO commands. Digitizing and editing artifacts significant enough to display at a scale of 1:100,000 were corrected. Within the database, geologic contacts are represented as lines (arcs), geologic units as polygons, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum.
Purpose:
The data set for the Chewelah 30' X 60' quadrangle has been jointly prepared by the U.S. Geological Survey Mineral Resource Program, the Southern California Areal Mapping Project (SCAMP), and the Washington Division of Geology and Earth Resources, as part of an ongoing effort to utilize a Geographical Information System (GIS) format to create regional digital geologic databases. These regional databases are being developed as contributions to the National Geologic Map Data Base of the National Cooperative Geologic Mapping Program of the USGS.
The digital geologic map database for the Chewelah 30' X 60' quadrangle has been created as a general-purpose data set that is applicable to other land-related investigations in the earth and biological sciences. For example, it can be used for mineral resource evaluation studies, animal and plant habitat studies, and soil studies in the Colville and Kaniksu National Forests. The database is not suitable for site-specific geologic evaluations.

Use_Constraints:
The Chewelah 30' X 60' geologic-map database should be used to evaluate and understand the geologic character of the Chewelah 30' X 60' quadrangle as a whole. The data should not be used for purposes of site-specific land-use planning or site-specific geologic evaluations. The database is sufficiently detailed to identify and characterize geologic materials and structures. However, it is not sufficiently detailed for site-specific determinations.
Use of this digital geologic-map database should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was compiled and edited at a scale of 1:100,000 means that higher resolution information may not have been uniformly retained in the dataset. Plotting at scales larger than 1:100,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, although higher resolution data is incorporated in most of the map, the resolution of the combined output will be limited by the lower resolution data.

Data_Set_Credit:
Technical review by Rowland Tabor and Kenneth Fox led to significant improvements that eventually were reflected in aspects of the database, the plot file, and in the description of the geologic units of the Chewelah 30' X 60' quadrangle.
Geologic mapping and digital preparation of this report were sponsored jointly by (1) the National Cooperative Geologic Mapping Program of the U.S. Geological Survey, (2) the Washington Division of Geology and Earth Resources, (3) the Southern California Areal Mapping Project (SCAMP), and (4) the Mineral Resources Program of the U.S. Geological Survey. In our digital preparation of the data set, carried out in the Geographic Information System laboratory of the Mineral Resources Program of the U.S. Geological Survey in Spokane, Washington by Pamela M. Cossette and Pamela D. Derkey, we received valuable assistance from Paul C. Hyndman and from Rachel Hauser at the SCAMP Geographic Information System laboratory in Riverside, California.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Geologic-map units in the Chewelah quadrangle database were described using standard field methods. Consistent with these methods, the database author has assigned standard geologic attributes to geologic lines, points, and polygons identified in the database.
Nation-wide geologic-map accuracy standards have not been developed and adopted by the U.S. Geological Survey and other earth-science entities. Until such standards are adopted, the SCAMP project has developed internal map-accuracy standards for 1:100,000-scale geologic maps produced by the project.
Geologic lines and points on 1:100,000 scale geologic maps are judged to meet SCAMP's internal map-accuracy standards if they are located to within +/-50 meters, relative to topographic or cultural features on the base map.
Lines and points that meet (or may not meet) this SCAMP internal map-accuracy standard are identified both in the digital database and on derivative geologic-map plots. Within the database, line and point data that are judged to meet the SCAMP internal map-accuracy standard are denoted by the attribute code .MEE. (meets)in the appropriate data table; line and point data that may not meet the SCAMP internal map-accuracy standard are denoted by the attribute code .MNM. (may not meet).
On any derivative geologic-map plot, line data that are judged to meet the SCAMP internal map-accuracy standard are denoted by solid lines; line data that may not meet the SCAMP internal map-accuracy standard are denoted by dashed or dotted lines. There is no cartographic device for denoting the map-accuracy for geologic-point data (eg. symbols representing bedding, foliation, lineations, etc.).
Logical_Consistency_Report:
Polygon and chain-node topology present.
The areal extent of the map is represented digitally by an appropriately projected (UTM projection), mathematically generated box. Consequently, polygons intersecting the lines that comprise the map boundary are closed by that boundary. Polygons internal to the map boundary are completely enclosed by line segments which are themselves a set of sequentially numbered coordinate pairs. Point data are represented by coordinate pairs.
Completeness_Report:
The geologic map and digital database of the Chewelah 30'x 60' quadrangle contain new data that have been subjected to rigorous review and are a substantially complete representation of the current state of knowledge concerning the geology of the quadrangle.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The maximum transformation RMS error acceptable for 30' x60' quadrangle transformation and data input is 0.003 (7.6 meters). Horizontal positional accuracy was checked by visual comparison of hard-copy plots with base-stable source data.
Transformation data for the Chewelah quadrangle are as follows:
Scale (X,Y) = (2540.622,2540.193)  Skew (degrees) = (0.004)
Rotation (degrees) = (-0.377)  Translation = (421268.260,311632.232)
RMS Error (input,output) = (0.003,7.674)

L-SYMB stores appropriate line symbol value from the lineset geoscamp2.lin (included in the data package)
L-NAME formal name of fault
Geological point data includes site-specific information describing the types and the orientation of bedding, foliation, and lineations. One annotation subclass is included in the geologic points coverage, CHEW_PTS: anno.dip displays the respective dip and plunge values associated with individual point data.
Feature attribution and item definitions are as follows:
CHEW_PTS.PAT:

P-SYMB calls the point-type from the markerset geoscamp2.mrk (included in the data package)
P-TAG point tag which consists of a character(s) and numerical value, e.g. FN42, allows the user to relate the point entity to its corresponding definition in the data table, points.rel
Point types (quantitative orientation data) in chew_pts.pat and their corresponding, abbreviated descriptions from points.rel:
B1	Bedding, horizontal, sedimentary rocks
B2	Bedding, inclined, sedimentary rocks
B4	Bedding, vertical, sedimentary rocks
B6	Bedding, overturned, sedimentary rocks
B11	Bedding, wavy or crinkled, inclined, sedimentary rocks
B27	Bedding, inclined, volcanogenic rocks
FN13	Foliation, primary igneous, inclined
FN14	Foliation, primary igneous, vertical
FN42	Foliation, metamorphic, inclined
FN43	Foliation, metamorphic, vertical
CLV2	Cleavage, inclined
CLV4	Cleavage, vertical
L12	Lineation, crushed and streaked mineral grains, horizontal
L14	Lineation, crushed and streaked mineral grains, inclined
L37	Lineation, metamorphic, minor fold axis
P-DIP the dip of planar features
P-STRIKE the azimuth strike of planar features
P-DIPDIR azimuthal direction of dip
At present, it is not possible to indicate the cardinal direction of dip using traditional conventions (traditional geologic notation allows a quadrant designation following the dip value).
P-PLUNGE lineation plunge value
P-BEARING azimuthal bearing of plunge
The two coverages that provide base-map (DLG derived) geo-reference information are CHEW_HYPS (topographic contour data) and CHEW_TRANS (cultural data/roads). Both are line coverages.
In order to facilitate plotting of the topographic information available in CHEW_HYPS, original DLG-derived attribution was retained and two additional attributes added, LTYPE and ELEV. The added attributes allow the user to descriminate between, and selectively plot, contour data.
Similarly, in addition to the original DLG-derived transportation attribution available in CHEW_TRANS, three additional attributes were added, LTYPE, USROUTE, and STROUTE. They permit the user to identify and selectively plot the various road types included in the DLG data.
Cartographic line entities are contained in CHEW_XS (two cross-section traces) and CHEW_LDR (unit label leaders). These line entities have only one attribute, L-SYMB, and all have the same value, 1.
