Cover Story: Unmanned aerial vehicles (UAVs) are a rapidly evolving tool in geosciences and are increasingly deployed to study the dynamic processes of the earth’s surface. To assess the potential of low-cost UAVs for the monitoring of alpine glaciers, we conducted multiple aerial surveys on the Kanderfirn in the Swiss Alps and used novel open-source photogrammetry software for the generation of high-resolution orthophotos and digital surface models. The produced orthophotos and surface models document the rapid glacier surface changes over the melt season 2018 and highlight that self-developed fixed-wing UAVs in tandem with open-source software are an affordable alternative to commercial remote-sensing platforms and proprietary software.

Practical Tips for 3D Regional Gravity Inversion

  • Daniele Sampietro and
  • Martina Capponi

To solve the inverse gravimetric problem, i.e., to estimate the mass density distribution that generates a certain gravitational field, at local or regional scale, several parameters have to be defined such as the dimension of the 3D region to be con...
