GIS Best Practices for Mining

Years of previous mining activity had left numerous "stopes," open underground areas where ore had been extracted, and "drifts," horizontal tunnels that led from the access shafts to the ore bodies. In all, mining had been conducted at 20 different horizontal levels reaching 1,900 feet below ground level.
