Fringe 2005 extracted recommendations by session


Thematic Mapping and DEMs


  • The ENVISAT baselines should be maintained at least at the level they currently are.
  • Full-resolution SAR data should be disseminated online for quicker and more convenient access.

Methodology: Long-term DInSAR and Terrain Motion


  • In addition to the PSIC4 other datasets with reliable ground-truth information are desired in order to assess the performances of the different approaches under varying conditions.

Methodology: Advances in PSI


  • Scattering models must/can be improved, in particular scattering at buildings
  • Stratospheric autonomous HALEs (“Stratellites”) are promising platforms for remote sensing and should be studied in detail.

Ice and Snow


  • ESA proposed to change all background IM and WS acquisitions over Greenland and Antarctica from VV to HH.  No objections to this were raised.
  • Switch from VV to HH over polar land-ice
  • Keep on measuring with ENVISAT! 
  • True 3-D would be useful.  Investigate ascending + descending + alternative angle of incidence.  Investigate options for optimizing acquisition modes of different radars in orbit
  • Continue WS in the interior of Greenland and Antarctica. Encourage and support WS-WS interferometry 
  • Allocate some resources to IM mode in Greenland and Antarctica
  • Investigate options for easy ENVISAT-user access to ECMWF data and derived products
  • We would welcome:  A mechanism for easy ENVISAT-user access to magnetometer data
  • Further studies and measurement campaigns about PolInSAR are required.
  • For ice motion applications more channels should not be traded for spatial or temporal resolution
  • Another Tandem like (1- or 3-days repeat) configuration or a constellation is most wanted by the community         
  • Future missions should keep (or enhance) spatial resolution.  Enhanced temporal sampling is recommended



  • A concerted community effort to pool volcano InSAR monitoring results by existing research groups at the regional level should be undertaken.
  • A Global Observing System umbrella should be sought to provide an international conduit for results.
    • ESA support for this via Background Mission -type support would be necessary.

Earthquakes and Tectonics


  • More research is needed to assess the potential of MERIS in measuring atmospheric water-vapour variations.
  • Data from the ERS archives should become freely available and easily accessible
  • Envisat wide-swath data acquisitions should be continued to build up archives
  • The Envisat background mission is highly appreciated and very important and should definitely be continued (extended?)



  • For further developing and supporting the use of InSAR for operational landslide monitoring, long-term continuity of SAR missions is crucial
  • Provide new space-borne systems (C-band or L-band) with short revisiting time (several days)
  • Stimulate interaction between InSAR community and Engineering geologists community
  • Stimulate research aiming at integration of processed InSAR data into user practices
  • Standardisation of InSAR-derived landslide products would enhance the acceptance of the technique and products by the users
  • Improve accessibility of available JERS-1 data archived at ESA for InSAR purposes
