En ny geoide er på vej, og den skal være tilstrækkelig god til et nyt GNSS-baseret højdesystem. Geoiden vil blive bestemt ved en kombination af tyngdemålinger fra satellitter, fly- og overflademålinger samt GNSS målinger og nivellement. DT

People with disabilities rarely visit museums due to mobility issues in reaching and navigating museum buildings and difficulties in accessing artworks. This work addresses the latter problem, considering people with low vision. To this end, we prese

The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin Otter airplane of the Chilean

Repeated GPS measurements have been performed at the centre of the Greenland Ice Sheet since 1992. Results have shown that the ice sheet is essentially stable at this location, with GPS-determined strain and elevation change rates in good accordance

To date, operational airborne gravity results have been obtained using either a damped two-axes stable platform gravimeter system such as the LaCoste and Romberg (LCR) S-model marine gravimeter or a strapdown inertial navigation system (SINS), both w

In this study of the North Greenland ice sheet, we have used digital elevation models to investigate the topographic signatures of a large ice flow feature discovered in 1993 and a unique surface anomaly which we believe has not been observed previou

A new deep ice-core drilling site has been identified in north Greenland at 75.12° N, 42.30° W, 316 km north-northwest (NNW) of the GRIР drill site on the summit of the ice sheet. The ice thickness here is 3085 m; the surface elevation is 2919 m.T
