Environment-oriented Geomatics - Geosciences

The group's professional expertise covers geodesy, surveying, photogrammetry, remote sensing, GIS and cartography. The projects are conducted in satellite- an ground based gravity, GNSS, glaciology / geomatics, and satellite remote sensing.

Environment-oriented Geomatics

The group carries out research in the following areas:

  • Glaciology (glacier mass changes: surface energy balance modelling and observations, error assessment of geodetic and direct glaciological mass balance, and thermodynamic numerical ice volume modelling; calving of glaciers: observations from terrestrial photogrammetry, satellite imagers, and ground-based interferometric radar with subsequent multivariate statistical analyses of geodetic and geophysical data)
  • Geodynamics (post-glacial rebound and land uplift (i.e. visco-elastic processes and GIA processes), ocean tide loading at northern latitudes (elastic processes)
  • Temporal hydrological variability (observed from the ground and space)
  • Changes in soil surface (observed by remote sensing techniques)

PROJECTS

Gravity:

  • Gravity Investigations at Northern High Latitudes.
  • Investigations of Surface Loads of the Earth – Geometrical Deformations and Gravity Changes.
  • Validation and exploitation of GOCE data in Norway.
  • GRACE regional gravity field analysis for cryospheric applications.

GNSS:

  • GNSS Precise Point Positioning.
  • GNSS and Inertial Navigation Systems.
  • Velocity estimation from GNSS time series.
  • The tide analyzed by wavelets and classical Fourier methods.

  • Effects of land-use change on carbondynamics assessed by multi-temporal satellite imagery in a mountain watershed of Nepal.
  • SRTM DEM accuracy assessment over vegetated areas in Norway.
  • The road to deforestation: An assessment of forest loss and its causes in Basho Valley, Northern Pakistan.
