<abstract>The 42 georeferenced images included in this report represent digital images of geologic maps published by the U.S. Geological Survey (USGS) for an area surrounding and including the northern Rocky Mountains.   These rectified images were created for the purpose of visually comparing published geologic maps with other geospatial information in a geographic information system (GIS).  However, they cannot be queried or used for spatial analysis thus limiting their use in a GIS.   The images range in scale from 1:250,000 to 1:100,000.</abstract>
<purpose>These rectified images will allow for the quick comparison of geologic information with other datasets in a geographic information system (GIS).  Individual rectified images of previously published USGS geolgic maps can be viewed along with other digital data, or combined to form one large mosaic of map images for the entire area.  Furthermore, the rectified images 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.  Each image also quickly illustrates how the author intended to symbolize the map.</purpose>
<supplinf>This metadata file describes the 27 images in this report that are projected in UTM zone 12 NAD 1927 coordinate system.  This file applies equally to all images described herein, with the exception of those elements shown in the table below.  Such elements specific to individual raster images include Bounding_Coordinates in latitude and longitude (WestBC, EastBC, NorthBC, and SouthBC), Column_Count and Row_Count of pixels (width and height, respectively), and Coordinate_Representation expressed in meters (Resolution).

<horizpar>Rectified images were tested to ensure they were projected and georeferenced properly by overlying each image with mathematically-generated vector polygon spatial databases, grid tic coverages, or other rectified images.  For example, quadrangle map images were compared to a shapefile of 1:100,000-scale quadrangles, while other geologic map images were overlain with a latitude and longitude tic point coverage that was mathematically generated using ARC/INFO.  At the scale of publication, the images fall within the boundaries of the corresponding 1:100,000-scale quadrangle, or reference points on the images coincide with corresponding reference points of the tic file.</horizpar>

<srccontr>The full map extent of the original PDF image and marginal coordinate information, excluding the title, explanation, cross-sections, index maps, and other collar information, was used in this data set. 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.</srccontr>

<procdesc>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 only 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.  The RAGE tool is available from URL = http://www.3001data.com/3001website/main/downloads_files/rage/geotiff_header_repair.htm.</procdesc>

<procdesc>The original paper map was scanned and saved as a 300 dpi, 24-bit color TIFF image using an HP-4200 Designjet scanner.  The scanned TIFF image was cropped to include only the map and marginal coordinate information.  The resulting TIFF image was rotated and color balanced using Adobe Photoshop Elements 2.0.  A polygon shapefile of 1:100,000-scale quadrangles (hwquad100g.shp) was used to rectify the image with ArcMap 8.3.  Latitude and longitude intersections displayed on the TIFF image were tied to the corresponding quadrangle corner in the hwquad100g.shp file.  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).

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.</procdesc>

<procdesc>The original PDF was opened in Adobe Acrobat 5.0 and saved as a TIFF image format.  The TIFF image was cropped to include only the map and marginal coordinate information using Adobe Photoshop Elements 2.0.  A polygon shapefile of 1:100,000-scale quadrangles (hwquad100g.shp) and a GeoTIFF digital raster graphic (DRG) image of the Leadore 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 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 (latitude and longitude intersections) in the Leadore 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).

<procdesc>The original paper map was scanned and saved as a 300 dpi, 24-bit color TIFF image using an HP-4200 Designjet scanner.  The scanned TIFF image was cropped to include only the map and marginal coordinate information.  The resulting TIFF image was rotated and color balanced using Adobe Photoshop Elements 2.0.  A polygon shapefile of 1:100,000-scale quadrangles (hwquad100g.shp) was used to rectify the image with ArcMap 8.3.  Latitude and longitude intersections displayed on the TIFF image were tied to the corresponding quadrangle corner in the hwquad100g.shp file.  The rectified TIFF was then opened in LizardTech Geospatial Encoder 1.4 and converted to MrSID image format using a 10:1 compression ratio.
