This summer Bas Altena gave a keynote talk during the Innsbruck Summer School of Alpine Research 2019, Austria, on how to use the small CubeSat satellites to observe glaciers and processes on Earth.
Permafrost is found in about a quarter of the land area in the northern hemisphere. Unlike snow and ice cannot permafrost be "observed" with remote sensing techniques. However satellites collect data regarding permafrost from sensors in field, and permafrost can be modeled numerically using above-ground data sets of temperature and snow depth. In SatPerm we aim to see if such data sets can be used for modelling of permafrost.
A large international study - Global Land Ice Measurements from Space (GLIMS) shows that Earth’s glaciers are shrinking with only a few exceptions. The scientists behind the study have applied satellite images to study the glaciers over the recent decades. The comprehensive report is now published as a book and an e-book.
En stor internasjonal studie - Global Land Ice Measurements from Space (GLIMS) viser at jordens isbreer med noen få unntak minker i størrelse. Forskerne bak studien har benyttet satelittbilder for å studere isbreene over de siste tiårene. Den omfattende studien er nå publisert i boken; Global Land Ice Measurements from Space.
To better understand and describe the processes related to the Earth’s physical features and the society it is increasingly important to use remote sensing and geographical information systems (GIS) as tools for managing large amounts of spatial and geographically-referenced information.
