The Drone Infrastructure Lab
In the Drone Lab at Dept. of Geosciences we are operating drones to take high resolution photos of terrain and objects. The drones are operated by a certified pilot. The main drone, a Camflight C8 cover areas of more than 1 km2 in one flight with a ground res. of 3.5 cm at max altitude of 120 m. Lower height give higher resolution. Surveying of control points for georeferencing are offered by GNNS or classical surveying methods dependent on accuracy requirements. It is used in research and teaching, and services are also provided to external clients.

Instruments / Drones / Processing:
- Camflight C8 with Nikon Coolpix ACPS-C - 16Mpix camera. Flight time on a flight up to 40 minutes at 6m/s (c. 14 km flight distance on one set of batteries). Ground resolution (GSD) c. 3.5 cm at 120m max flying height.
- GNSS equipment; Altus APS-3G for RTK use with CPOS from the Norwegian Mapping Authority in areas with mobile phone coverage.
- Topcon Legacy GNSS – base + rover with radio RTK transmission for use in remote areas.
- Classical surveying with Leica TS is an option for smaller high accuracy surveys.
- Available software for processing includes Agisoft Photoscan, Trimble U.AS-Master as well as open source programs.
Description of services:
- We can offer a complete line of work – point to the area of interest, and we can take care of planning, ground control points, flying and processing with deliverables in agreed formats.
- Services as only flying or other parts of the process are also a possibility.
Processing data from the drone up to final deliverables of DEM’s and orthophotos are offered using different commercial software as well as open source.
The Drone Lab - How do we work?
Drones are used in geosciences to document changes at the ground level. Aerial photos taken with drones give an overview of big areas seen from above, and show more about what is happening at ground level.
Flying the drone is only a part of a project. Given an area of interest, a flight plan is made giving the flight lines with positions for each photo to be taken. Flying height is adjusted to meet the requirements of ground resolution.
If georeferencing (or model scale) is required ground control points (GCP’s) are placed in the area of interest and surveyed with an applicable method according to precision requirements. Flying the drone is preferably done in good weather conditions (low wind – no precipitation) and sunny or thin cloud cover conditions.
Processing is mainly unattended, but some manual measurements (of GCP’s in images) are required. Deliverables includes DEM or DSM’s – orthoimagery and 3D models in standard formats.
The Drone Infrastructure Lab can by appointment assist in research activities or/and assist students at the Department of Geosciences.
