  3. 3. PITMAPPING DIGITAL MAPPING IN THE PIT AT CORTEZ AND NORTH MARA Digital mapping is something the mining industry has been exploring for years. A lot of “solutions” have been proposed over the years, but there were almost always problems with the hardware or software, and often both. The eventual benefit of collecting mapping data digitally was usually determined to be not worth the effort. Recently, however, Tom Whittle, at the Cortez mine, has spearheaded the development of a truly user-friendly, high productivity ArcPad-based digital mapping application that has proven its worth in the Pipeline and Cortez Hills open pits. This application was recently implemented at North Mara, to rave reviews, and is currently being[3] adapted for Exploration surface mapping.
