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.
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.
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)
Affine X = Ax + By + C
Y = Dx + Ey + F
A = 2540.567 B = 16.874 C = 421268.260
D = -16.718 E = 2540.137 F = 311632.232
Are there legal restrictions on access or use of the data?Access_Constraints: None
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.
The U.S. Geological Survey (USGS) provides these geographic data "as is. "The USGS makes no guarantee or warranty concerning the accuracy of information contained in the geographic data. The USGS further makes no warranties, either expressed or implied as to any other matter whatsoever, including, without limitation, the condition of the product, or its fitness for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers at the USGS, no warranty, expressed or implied, is made by the USGS regarding the use of these data on any other system, nor does the fact of distribution constitute or imply any such warranty.
In no event shall the USGS have any liability whatsoever for payment of any consequential, incidental, indirect, special, or tort damages of any kind, including, but not limited to, any loss of profits arising out of use of or reliance on the geographic data or arising out of the delivery, installation, operation, or support by USGS.
This digital, geologic map database of the Chewelah 30' x 60' quadrangle, 1:100,000 map-scale, and any derivative maps thereof, is not meant to be used or displayed at any scale larger than 1:100,000 (e.g., 1:24,000).
