Service to the photogrammetric mapping industry has long been Keystone’s core business. We fly precise stereo imagery and simultaneously collect airborne GPS and IMU data to support photogrammetric rectification. Whether digital or film, we can provide the raw image materials you need to compile vector mapping or generate ortho-images.
With our fleet of 19 survey aircraft, we are able to respond quickly to brief windows of suitable weather. And with our UltraCam digital mapping cameras, we integrate with your in-house processes to achieve an efficient and highly accurate all-digital workflow. Our UltraCams also offer added value with the availability of the near infrared band and 16-bit image depth. In the hands of experienced photogrammetrists, this multispectral data and rich bit-depth support advanced image analysis and feature extraction.
With contemporary stereo coverage of nearly 300 US cities, our digital image library is a cost-effective alternative to new image acquisition. Most digital library imagery is flown with ABGPS and IMU at GSD’s of 15cm or 30cm. The image library is accessible through our web portal, KASView
, which makes it easy to identify and order the specific images covering your project area. For projects having stringent image collection requirements, custom acquisition flights
can be scheduled to obtain data that meets your exact specifications.
