AIRBORNE CAMERA SIGHTS SITES

A cheaper way of obtaining aerial photographs of construction sites is reported. Designed for one man operation, the system described involves the use of a small helium filled balloon, 8.5 M long and 3 M in diameter, carrying a payload consisting of a high definition still camera linked on a motorised boom with a video TV camera. The balloon is manufactured from a modern treated nylon material, and is of cigar shape for aerodynamic reasons to provide a stable platform for the photographic equipment. The helium gas is stored in a trailer attached to a land rover. Controlled by radio, the boom mounted assembly can be moved through any dimension. This means that the ground operator can select exactly the photograph required before closing the radio switch which triggers the camera shutter. Photographs are presented to indicate the coverage provided by the camera equipment, which can be taken up to 70 M by the balloon. The cost of photographic coverage of a site on a one visit basis is given as 45 pounds sterling in the GLC area, and outside London the price rises from the 45 pounds sterling per base rate per visit in line with a 16p mileage charge. /TRRL/
