Geomatics and remote sensing
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.
Risk of avalanches and landslides direction is an example of what can be calculated using a geometric analysis. Illustration: Department of Geosciences.
About the group
Geomatics includes collection, management, integration, representation, analysis, modeling, and visualization of geographically-referenced information. Data is collected by mapping using GPS, or by remote sensing from aerial, satellite or ground based sensors. Data is further managed and analyzed in a geographical information system (GIS).
Geomatic tools and techniques are used by all our research groups, both within environmental studies, hydrology, water resources, geomorphology and geohazards. Examples of projects are geohazards and slope instability, glacier mapping and change detection, permafrost modeling, snow distribution and landform analysis.
