RESE Project


Distrubution maps of chl (a), SPIM (b) and ay (c) in Lake Malaren calculated according to algorithms based on historic data. Sampling points 4 and 5 are circled in (a) and the transect of the boat is overlaid in (b). All land pixels have been removed.


Long-term goals:
  • A demonstration project on algae bloom detection
  • A reflectance model adapted to class 2 waters, i.e. the Baltic Sea and applied to satellite data obtained from, for example SeaWiFS.
  • Airborne hyperspectral analysis for aquatic applications
  • An airborne hyperspectral analysis system for simulating satellite data, useful for planning new instruments.
  • A subproject dealing mainly with the detection of coral bleaching was also included in the RESE framework. See separate project or link "Coral reef studies below"


  • Strategies:

    This project covers fundamental analysis problems of ocean optics and atmospheric influences on ocean satellite data. These methodology problems are necessary to solve for retrieving quantitative estimates of ecological variables. In this respect the project indeed is helpful for monitoring agencies, surveillance work and research community.

    Airborne hyperspectral studies can improve and adapt image analysis at regional scale and guide satellite and airborne instrument development. Remote sensing methods for waste water influence on coastal ecology is established.

    The RESE-project is described in more detail here.

    The Centre for Image Analysis has participated in this project within the two main areas: – Semianalytical modelling to determine water quality from satellites using a substantial amount of field data and CASI imaging spectrometer data and investigation of possibilities to use high resolution satellite data for detection of coral bleaching. They are presented here as two different sub-projects:

  • Modelling of water quality

  • Coral reef studies
