How to calculate contour lines

3Dsurvey software combines thousands of aerial drone imagery to provide the ultimate mining surveying tool.

Compared to traditional technology that is labour and cost intensive, drone-based mapping of open-pit mines, quarries and pits by generating point clouds, DSMs and orthophotos adds to safety, cost-efficiency and accuracy.

3Dsurvey has an extremely useful, fast and precise tool that empowers you to generate and calculate contour lines in seconds.
