  • Indoor Mapping, UI and IoT
  • High-resolution imagery and remote sensing, real time data, UAV’s

Geodesy

  • Geodesy is the science of accurately measuring the Earth's size, shape, orientation, mass distribution and the variations of these with time.
  • e.g. How high is Mt. Everest ? Why ?
  • Measuring Groundwater/drought analysis

GPS / GNSS

  • Satellite based pseudo time ranging, terrestrial
  • Resolution and accuracy
  • Orbits, atmospheric  delays, clock  offsets
  • How precise can we be (project question) ?
  • DGPS
  • RTK

Cartography

Cartography

  • Representation (colour, distributions)
  • Summary at bit.ly/fakemaps
  • Project on representation and perception

Remote Sensing Photogrammetry

Drone Photogrammetry

  • Structure from Motion (SfM) – based on Scale Invariant Feature Transform (SIFT) (Lowe, 1999)
  • Large variety of drones, payloads possible
  • Project – getting the most out of drone based photogrammetry
