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.

The contours were created by 'gridding' the irregular LiDAR
data to produce a Digital Elevation Model (DEM).
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.
Products
for this job included LiDAR data, contour maps, imagery and
digitised features plus ground surveyed boreholes locations.
