Flight & Imaging

 

Using Unmanned Aircraft Systems (UAS) for photogrammetric aerial mapping provides surveyors and other geospatial professionals with a revolutionary tool for collecting data that was once reserved for large photogrammetry specialists.

Our aerial photography collection is arranged by flight.  A flight is a discrete collection of images, typically gathered by a single aircraft in one day.  Each flight that is available for research has a database record describing the geographic extent of the flight, the parameters of how the images were created (altitude of aircraft, scale of the resulting images), the formats that we have in the collection (film vs. print; color vs. black & white), and other metadata for the flight. 

The parameters of the photogrammetric project are the following:

  1. boundaries/borders of the photographed area;
  2. model of the camera and its parameters;
  3. expected scale of photographic images;
  4. longitudinal and transversal overlapping of photographs;
  5. flight direction;
  6. flight speed;
  7. flight height;
  8. Data coordinate system.

The UAV operational time determines the dimensions of the photographed area boundaries/borders; the latter depend on the type of the installed motor.
