Larsen, J.C. Assmus, K.C. Causey, J.D. Zientek, M.L. 2004 raster digital data U.S. Geological Survey Data Series DS 106 Menlo Park, CA U.S. Geological Survey 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. absk_beartooth_rect.sid is a rectified (georeferenced) MrSID image format file that was derived from an unpublished rectified TIFF image format file which, in turn, was created by converting a PDF version of a published map by Van Gosen and others (2000). en 2000 Publication date of original map Complete None planned -117.034173 -115.960822 48.012857 47.489396 497261.309221 658883.760925 5068865.283158 4981096.583132 None geologic map rectified raster image digital image georeferenced image Absaroka Range Beartooth Mountains Montana USA none This digital image is not meant to be used or displayed at any scale larger than 1:250,000 (for example, 1:2,000).

RAster Georeference Enabler (RAGE) 1.1.17. 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 latitude and longitude tic points coverage (tic120602utm) that was mathematically generated using ARC/INFO. At the scale of publication, reference points on image coincided with corresponding reference points of the tic file. N/A Van Gosen, B.S. (comp.) Elliott, J.E. (comp.) LaRock, E.J.

Even though Van Gosen and others' (2000) geologic map was published at a scale of 1:126,720, the geology was actually mapped on a 1:250,000-scale topographic map base that had been unlarged to 1:126,720. Thus the resolution of the mapping is only as good as the base map component. The original PDF was opened in Adobe Acrobat 6.0 and saved as a 300 dpi, color TIFF image. Using Adobe Photoshop Elements 2.0, the TIFF image was cropped to include the map and marginal coordinate information and then color balanced. A polygon shapefile of 1:100,000-scale quadrangles (hwquad100g.shp) and a UTM projected tic coverage of latitude and longitude coordinate points (tic120602utm) were used to rectify the image with ArcMap 8.3. Two corners of the image were tied to the corresponding quadrangle corners in the hwquad100g.shp file. Where additional latitude and longitude intersections were displayed on the source map, they, too, were tied to their respective locations (tics) in the tic120602utm coverage. The rectified TIFF was then opened in LizardTech GeoExpress 3.0 and converted to MrSID image format using a 10:1 compression ratio. The resulting image file has a SID (*.sid) extension. 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.
