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.
Sandpoint_rect.sid is a rectified (georeferenced) MrSID image format file that was derived from an unpublished rectified TIFF image format file which, in turn, was created from an EPS-format map file by Miller and others (1999).

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.
Sandpoint_rect.sid has a horizontal accuracy of no better than 51 meters, which reflects the resolution of the reference file, hwquad100g.shp. The rectified image was tested to ensure it was projected and georeferenced properly by overlying it with hwquad100g.shp, a polygon shapefile of 1:100,000-scale quadrangles. Hwquad100g.shp was derived from the mathematically generated file, topoq100.shp, which was obtained from ESRI Data & Maps 2002 (CD 2) and is distributed as part of ESRI software. The positional accuracy for topoq100.shp, and thus hwquad100g.shp is 51 meters. By visual inspection at the scale of publication, the image fell within the boundaries of the four corresponding 1:100,000-scale quadrangles.

The full map extent of the original EPS-format map file and marginal coordinate information, excluding the title, explanation, cross-sections, index maps, and other collar information, was used in this data set.
The encapsualted post script file of the original plot file was opened in Adobe Acrobat Distiller and saved in Acrobat portable document format (*.pdf) file. The PDF was opened in Adobe Photoshop Elements 2.0 and saved as a 300 dpi, color TIFF image. The TIFF image was cropped to include the map and marginal coordinate information. The resulting TIFF image was color balanced using Adobe Photoshop Elements 2.0. A polygon shapefile of 1:100,000-scale quadrangles (hwquad100g.shp) and an ESRI coverage of latitude and longitude cordinate points (tic120602utm) were used to rectify the image with ArcMap 8.1. The four corners of 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 (tics) in the tic120602utm coverage. 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.
