This rectified map image was created for the purpose of directly comparing an image of the original geologic map with other geospatial information. The rectified image includes the map and coordinate labels; titles, text, explanations, cross sections, and collar information were cropped.
This rectified image was created to allow the direct comparison of a published geologic map with other geospatial information in a geographic information system. The rectified image can be compared to vector representations of the same map to ensure that features are coded correctly and that all geologic information on the published map was captured in the vector files. The image also quickly illustrates how the author intended to symbolize the map.
GallatinNF_N_rect.sid is a rectified (georeferenced) MrSID image format file that was derived from an unpublished rectified TIFF image format file which, in turn, was created by scanning a paper copy of the original map by Wilson and Elliott (1997).

Raster Dataset
The title, text, explanation, cross section, index maps and collar information of the original data source map are cropped or partially cropped in the georeferenced MrSID image.
The rectified image was tested to ensure it was projected and georeferenced properly by overlying it with a rectified digital raster graphic (DRG). At the scale of the publication, reference points on the image coincided with corresponding reference points on the DRG.

The full map extent of the original paper map and marginal coordinate information, excluding the title, explanation, cross-sections, index maps, and other collar information, was used in this data set.
The original paper map was scanned and saved as a 300 dpi, 24-bit color TIFF image using a Colscan scanner at the TeckCominco Spokane Office. The scanned TIFF image was cropped to include the map and marginal coordinate information. The resulting TIFF image was rotated and color balanced using Adobe Photoshop Elements 2.0. GeoTIFF digital raster graphic (DRG) images of the Livingston 1:100,000-scale quadrangle and the Ringling 1:100,000-scale quadrangle were used to rectify the image with ArcMap 8.1. Latitude and longitude intersections displayed on the TIFF image were tied to the respective latitude and longitude intersections displayed on the corresponding DRG. The rectified TIFF was then opened in LizardTech Geospatial Encoder 1.4 and converted to MrSID image format using a 10:1 compression ratio. The resulting files include the image data (*.sid) and a world file (*.sdw). ArcGIS did not recognize coordinate information for these files, so 3001, Inc.'s RAster Georeference Enabler (RAGE) tool was used to associate coordinate information with the MrSID image. The RAGE tool is available from URL = http://www.3001data.com/3001website/main/downloads_files/rage/geotiff_header_repair.htm.
