Wetland Information Maps and Indicators

The first set of GlobWetland II geo-information maps will be produced for 3 points in time (1975-76, 1990-91, 2005-06), on the 200 wetland sites, at a geographical scale of 1:50,000 to 1:100,000, taking full advantage of the time series of Landsat data (MSS, TM and ETM):

  • land-use and land-cover maps, including wetland typologies;
  • change detection maps for long-term change and trends analysis;
  • water cycle maps for the analysis of the annual variations of the water table.

Two types of wetland indicators shall also be produced for the same points in time (1975-76, 1990-91, 2005-2006), making the best use of the wetland geo-information maps produced over the 200 wetland sites:

  • Ramsar Indicators of effectiveness (defined by the STRP);
  • Indicators on the status and trends of Mediterranean Wetlands (defined by the OMW).
