Unmanned Aerial Vehicle (UAV) surveys are provided with the Aibotix Aibot X6 V2 Hexacopter combined with real-time-kinematic GPS positioning and a variety of sensors.

The main applications and advantages of UAV surveys include:

  • Create accurate geo-referenced point clouds, digital terrain models, orthophotos, and thermographic images with unprecedented resolution and efficiency
  • Surface change detection through time-lapse evaluation
  • Inspection of inaccessible objects, including rock outcrops in alpine terrain, large dams, high voltage lines, wind turbines, etc.
  • Documentation of complex construction sites

Our onboard sensors include:

Interactive Gigapixel Panoramic Photography (Gigapans)

Gigapans are panoramic digital images with billions of pixels, providing an unprecedented combination of detail and perspective. Gigapans are shared online with clients and colleagues, and can be explored at www.gigapan.com. GigaPan offers the first solution for shooting, viewing and exploring the images in a single system that includes:

  • The EPIC series of robotic camera mounts to capture photos;
  • GigaPan Stitch Software to automatically combine thousands images into a single composite image; and
  • The Gigapan.com website, offering a unique interactive viewing platform.

The GigaPan EPIC series is based on the same technology employed by the Mars Rovers, Spirit and Opportunity, to capture high resolution images of Mars. GigaPan was formed in 2008 as a commercial spin-off of the research collaboration between a team of researchers at NASA and Carnegie Mellon University.

Some of the main applications of GigaPan technology in the context of engineering geology and civil engineering (with representative examples) include:
