Remote sensing

Remote sensing allows the identification of objects and processes at distance, generally by means of electromagnetic radiation that objects reflect or emit. Remote sensing allows the covering or large territories synoptically, often in a repetitive manner and obtaining data which are much more valuable than that in the visible spectrum corresponding to traditional aerial photography. 


At CREAF there is an established tradition of applied studies in this area, using satellite data at very different spatial and temporal resolutions, as well aerially-captured data. Also, combined use with data such as LIDAR is now beginning. 
The services offered in this are of different types: 
  • Methodological, such as radiometric and geometric treatment to improve information obtained from images, or new techniques of digital classification
  • Cartographic, such as annual detection of wildfires based on long temporal image series
  • Applied, such as studies of landscape dynamics or understanding the migration of marine birds
  • Conceptual, such as contributions to metadata standards in remote sensing images, or the implications of degradative image compression
