A pivotal component of MARSAIS was the assessment of user requirements for SAR data in the coastal and marine environment. MARSAIS identified and involved potential end users of SAR data and generated end user feedback which in turn was fed into the development of a MARSAIS prototype focussing on sea state, (winds and wave), oil spills/slicks, surface currents (and internal waves) and synergy.
MARSAIS generated end user feedback and fostered interaction with end users from the coastal and marine community by:
Disseminating a questionnaire on the use of SAR data.
Communicating directly with individuals via phone/e-mail and utilising mailing lists to promote MARSAIS activities.
Attending conferences and trade events over the course of the project.
Hosting three dedicated workshops on the use of SAR data in the coastal and marine environment.
Among the key findings of the interaction and response from the end users the following are highlighted:
The issue of cost was cited as a significant limiting factor in the use of SAR data.
Capability (training and skills) and capacity (infrastructure) also influence the use of SAR data in the coastal and marine environment.
There is potential for the further development of SAR data through continued basic and applied research into SAR applications in the coastal and marine environment.
The examination of current features, shallow water bathymetry and pollution incidents were the preferred applications to emerge.
The finding and recommendations emerging from MARSAIS are of relevance to GMES. Detailed analysis of the end user feedback is contained in the User Requirements Document.
