Skeye travelled 2000 kilometres north to survey one of Europe’s largest stone quarries. Bremanger Quarry lies a couple of hours driving North of Bergen in Norway at a latitude of 61 degrees North. The quarry produces mainly granite for road construction and stabilising offshore pipelines. The quarry is situated at a height of 500 meters above the Fjord of Svelgen. The first task was to install around fifteen ground control points that were subsequently measured using GPS. Following this six flights were conducted using the Microdrone MD4-1000 unmanned multicopter to cover the entire quarry with aerial images.The aerial imagery was used to create a 3D height model of the entire quarry. From this the height contour lines were extracted. An orthophoto mosaic was also produced for the customer. This was created by stitching together all the individual images and correcting them for height differences in the terrain.
In addition Skeye was asked to produce six aerial 360-degree panoramic images and a video covering the activities of the quarry. These were made using the Altura V1 multicopter.
