A bit late, but a good source of wetland mapping information from the the GlobWetland Symposium: Looking 
Lake Bogoria in Kenya, Landsatat wetlands from space. The GlobWetland project was launched in 2003 with the aim of developing and demonstrating earth observation-based information services to support wetland managers and national authorities worldwide in responding to the requirements agreed under the Convention. The project involved 50 different wetlands in 21 countries and relied on the direct collaboration of several regional, national and local conservation authorities and wetland managers. It has now produced a number of standardised information products (e.g. land use and land cover maps, change-detection maps, water cycle regime maps and others) validated over the 50 selected sites by the users themselves, consolidated methods and guidelines for the users to continue the work after the project lifetime.
The GlobWetland Symposium was held in October 2006 in Frascati, Italy to inform the general public and policy makers of the importance of wetlands and to promote their conservation and protection worldwide. The papers in this special issue highlight the major points and recommendations derived from the Symposium while the final conclusions provide a basis for initiating new actions within the ESA in support of the EO requirements of the Ramsar Convention and the wetlands community.
The special issue in Journal of Environmental Management from the conference has many interesting papers on wetlands mapping.
