A3 Edge Digital Mapping System Upgrades Oblique Capabilities

Tel Aviv, Israel, July 30, 2015 — VisionMap announced today the introduction of upgraded oblique capabilities to its A3 Edge Digital Mapping System. The A3 Edge camera, well known for its high capture productivity, now utilizes a proprietary Roll Stabilization Technology that increases its efficiency even further, particularly for oblique projects.

The A3 Edge camera collects images by means of two telescopes that “sweep” from side to side to create an extremely wide 106° field of view. Each sweep captures oblique and vertical images simultaneously. The new Roll Stabilization Technology shortens the time it takes to complete each sweep, allowing for even faster coverage of the entire area. Productivity is increased for orthophoto, and especially for oblique production.

The A3 Edge Digital Mapping Camera and another oblique camera both surveyed an area of 1400 km2 in Georgia, US. A3 Edge completed the survey in 3.5 hours at 16 cm GSD, collecting vertical and oblique imagery of the entire area, while the other camera took 7.1 hours to cover the area at 25 cm GSD.

VisionMap’s A3 LightSpeed automatically processed the imagery and generated a 16 cm orthophoto in 26 machine hours. The other camera’s imagery required 50 hours of machine processing to generate the 25 cm orthophoto. The huge difference was in the amount of manual work – the other camera required an additional 100 hours of manual processing, whereas the A3 data from LightSpeed required less than 10 hours. Overall, the highly productive A3 Edge system completed the project over two times faster.
