In 2014 Skeye carried out an additional two projects in Angola. For the Angolese government a number of large areas in the vicinity of Luanda were mapped using drones.
The drones used by Skeye are of the type Bird-Eye (Quest 300). These are fixed unmanned aircraft equipped with a geometrically calibrated camera to take aerial photographs. These photographs, around 80,000 for the two projects, are taken in a special pattern. This pattern is pre-programmed so as to ensure that every image overlaps with the next with a certain percentage. Using additional measurements on the ground with RTK GPS all the images can be stitched together and assigned with the right coordinates.
From the imagery a very detailed 3D digital terrain model was generated and all objects such as houses, roads and vegetation were mapped.
