Remote Sensing

Earth observation is used to increase knowledge in applied research of geosciences in the institutional competences.

Remote sensing data and tools, given the synoptic potential of capturing information and quantitative characterization, apply to different topics:

Georesources

  • geological and mineralogical mapping
  • characterization of mining areas throughout the mine life cycle
  • geothermal energy

Geohazards

  • volcanology
  • mass movements
  • coastal variations

Environment

  • land cover and geoenvironmental maps
  • multitemporal analysis for change detection and monitor relevant parameters (e.g. pH related to acid drainage)

The data captured in airborne or spaceborne platforms, with variable spectral and spatial resolution, are predominantly optical, multispestral and hyperspectral, but also from active sensors. The development of multi-source processing methodologies includes ancillary data from terrain, geochemistry, geophysics and geology, among others.

Examples of data and products used:

  • Landsat, ASTER, Sentinels (Copernicus), QuickBirdTM
  • SPECIM Eagle Hawk, HyMapTM, Hyperion

The LNEG is member and collaborates with remote sensing research networks:

  • Collaboratorium for Geosciences (C4G) (WP8)
  • Copernicus Academy
  • Earth Observation and Geohazards Expert Group (EOGEG)
  • Group on Earth Observations (GEO)
