Step 2 -- Scanning

Scanned mylar

This is a scanned image of part of the second set of Mylar maps containing only the geologic information. These Mylar maps are scanned and converted to bi-level tiff images at a resolution of 400 dpi. Once the scanning is completed, the resulting images are then georeferenced and converted into ARC/INFO grids. These grids are then used in Step 3.
