Orthophotography

Airborne Scientific collects and produces digital orthophotography utilizing our state of the art digital sensor with integrated survey grade gps and inertial measurement unit to maximize accuracy and minimize cost. Orthophotography is aerial photography corrected for lens distortion and terrain relief, and provides the appearance of a photo with the geometric fidelity of a map.

The combined use of survey grade GPS and an inertial measurement unit integrated into the sensor greatly reduces or even eliminates the requirement of costly ground control for orthophotography projects.

Advantages of GPS/INS include:

• Major cost savings by reduction or elimination of costly ground control.
• Improved processing efficiency for collection of Aerotriangulation and Ground Control.
• Capability of excellent accuracy even in remote or inaccessible areas.
• Excellent accuracy in corridor, spot, or single strip applications.
  
  
  

Orthophotography produced by our digital system also takes advantage of all the advantages of digital over scanned film mentioned in the Aerial Photography Page.

We can collect and produce very high resolution orthophotography, up to 5cm GSD (Ground Sample Distance) resolution conventionally and higher resolutions via helicopter. Imagery, mosaics, and tiled scenes can be delivered in a variety of formats including geotiff, ecw, jpeg2000, pix, and others. We can also accomodate your datum and projection requirements, including State Plane, UTM, and local.
