Aerodata delivers first 2.5cm GSD orthophoto mosaic

June 27, 2008 -- Today Aerodata International Surveys marks another milestone in the ever-evolving industry of aerial surveying: the delivery of an orthophoto mosaic with 2.5cm GSD (ground sampling distance) or 1 inch.

The area, a municipality in the Netherlands, was captured with one of Aerodata’s 3 Vexcel Ultracams and consisted of around 400 images.
It has gone through aerial triangulation, DTM production and orthophoto mosaic production.

This level of detail (roughly the size of a 2 Euro coin ) is new to the market, but certainly will gain in popularity very quickly amongst government officials and the general public.

A major side benefit is the fact that projects of this type are flown below restriction height in the major part of TMA's (Terminal Control Area) around major international airports. This enables to execute photo missions which become virtually impossible due to air traffic congestion. For instance: the present sample was taken only a few kilometers in front of a landing runway of Schiphol airport in The Netherlands.

About Aerodata Int. Surveys


Aerodata International Surveys is an independent private airborne surveying and mapping company founded in 1992 and located at Antwerp Airport, Belgium. It specializes in airborne spatial data acquisition of the earth’s surface and its advanced processing into geo-information products.

The area of operation is mainly Western and Southern Europe, but the aircraft are also deployed to Africa and the Middle-East and are available for projects elsewhere.

Early 2004 Aerodata was the first European company to own and operate a Vexcel UltraCam-D digital photogrammetric frame camera and since then over 300.000 UltraCam exposures were collected.

Aerodata Int. Surveys operates at least 4 aircraft at any given time with various sensors, among which the UltraCam’s, and their Aerodata PixelPipe, yielding tremendous throughput by heavy storage and processing infrastructure adds to the fit-for-purpose customer-oriented approach.
