International aerial mapping company Bluesky has completed another successful survey season in the UK and Ireland. Capturing around 70,000 square kilometres of aerial photography – of which about 70 percent is high resolution – the total area flown equates to around twice the size of the Netherlands. In addition to the true ortho photography, which is used to create 3D height models of the earth’s bare surface (Digital Terrain Models / DTM) and ground features including buildings and trees (Digital Surface Models / DSM), Bluesky has captured Colour Infrared imagery of the entire area. This CIR imagery can be used to create environmental maps which help determine the health and state of vegetation. Bluesky has also been busy capturing vertical and oblique imagery and LiDAR (Light Detection and Ranging) data of London and other cities, using the world’s first hybrid airborne sensor, for its MetroVista urban mapping programme. www.bluesky-world.com
