Frequently Asked Questions

What is an Orthophotograph?

An orthophotograph or 'ortho' is a photograph or image of the ground surface which has been processed and projected to have the geomtrical properties of a map. A normal aerial photo will have a variety of distortions in the image which will not be accurate to the ground surface, the ortho combines the aerial image with a model of the ground elevation (DEM) and the distortion properties of the camera to make a map accurate image.

What type of image licensing is available?

We can accomodate whatever method you require. The most economical is where we own the data and license its use to you, but if you wish to resell or distribute the data, we can arrainge that as well.

Can you provide the DEM for the orthophotography?

Airborne Scientific can produce a digital elevation model (DEM) for your orthophotography, or assist you in obtaining a suitable DEM for your requirements. We can produce DEM's from our stereo imagery depending upon terrain and land cover conditions.

What is the smallest resolution that you can collect?

We can collect imagery at any resolution that you require. Our unique digital sensor can be operated from an available helicopter for extremely high resolutions, and our conventional fixed wing aircraft can accomodate 5cm GSD imagery convieniently. We also utilize a close-range photogrammetric system which can be used for precision measurement on ground based projects.
