Geophoto Services was once a competitor to TGA in Denver Colorado.  It was purchased by Texas Instruments and later Western Geophysical. John Hollberg acquired this mapping library from Western Geophysical to combine with our other mapping libraries.  While a great deal of this mapping covers areas contained in our other libraries it does contain a great deal of coverage in South America, Africa that are not covered by our other mapping.

Most of this mapping was prepared using air photographs at the scale of 1:20,000.  Each set of air photographs were studied stereoscopically and annotated with visually estimated dips and strikes, faults and fracture patterns, fold axes, and geomorphic evidences of structure
