Aerial photo-mapping company BlueSky has launched a new digital imaging service to create cityscapes using high resolution aerial photography and 3D computer modelling. With highly-realistic 3D visualisations, displayed on PC screens, viewers can fly around towns and cities from the air or near the ground viewing streets and buildings from any direction and any angle.
BlueSky already supplies country-wide aerial photography and is currently re-photographing many towns and cities in super-high resolution using new digital camera technology. The cityscapes are computer-generated by matching images taken from different angles in a process called photogrammetry. BlueSky also uses building height and 3D landscape data from Intermap’s NEXTMap Britain terrain map and other highly accurate height information captured by airborne laser scanning (LiDAR).
