The three surface mining divisions of the Department for Natural Resources use a geographic information system (GIS) to capture, query, display and store spatial data. GIS technology allows department staff to combine different data resources linked to a specific location and display the information visually, usually on a map.

GIS is employed in many aspects of the daily operations of the divisions. Laptop computers and customized GIS software enable field staff to display permit locations in relation to other geographic features during mine site visits and complaint investigations. Used in conjunction with global positioning system technology, GIS can provide immediate and accurate locational information in the field.

In the office, permit reviewers, engineers and managers can view mine locations, permitted boundaries and related information on desktop computers along with site-specific topographic maps, aerial photographs and satellite imagery.
