Surveying 240 miles north of the Arctic Circle presents many challenges, but Lidar provided a rapid and detailed survey to enable the design of a new open pit mine, plus access road to/from the camp/dock location, 600 below.

Lidar can be fixed wing or helicopter based

Well someone has to do it

Difficult access to closed mine entrance. The aerial survey for the new open pit needed to be linked to the older undeground workings, where waste from the new pit would be placed.
Image (below) shows aerial photography with 10meter contouts overlaid. The contours were created by 'gridding' the irregular LiDAR data to produce a Digital Elevation Model (DEM).

Products for this job included LiDAR data, contour maps, imagery and digitised features plus ground surveyed boreholes locations.
