Mine surveyors may also establish the boundaries of mining claims. Some mine surveyors choose to move into mine management and others upgrade their qualifications to become mining engineers. Mine surveyors measure and set out underground and open cut mine workings in full detail Photogrammetrists extract spatial information from aerial or terrestrial photographs and from digital imaging systems using satellite and airborne sensors. Aerial photogrammetry is currently the major method of producing base maps and topographic maps. Terrestrial photogrammetry has applications in areas such as medical image analysis, dam and mine deformation surveys, and structural analysis of bridges.
Precise surveyors work at the highest accuracies of measurement technology.
Industrial applications include installation, alignment and monitoring of large machinery, such as nuclear accelerators, turbines and radio telescopes. Engineering opportunities include deformation monitoring of natural and constructed features, such as fracture zones, dams and high buildings. Remote sensing specialists use digital data acquired from high resolution satellite and airborne imaging systems to monitor changes on the surface of the earth. They are involved both nationally and internationally in numerous resource and environment related applications, in forestry, agriculture and water resource management, and the monitoring of global change. Many other career options exist.
