The integration of the AHP with GIS combines decision support methodology with powerful visualization and mapping
capabilities which in turn facilitates the creation of land use suitability map [15]. Thus, the present study
is an attempt to identify potential ecotourism sites using AHP and GIS in Surat Thani Province, Thailand.
This is also an additional benefit achieved by integrating geo-scientific aspects in the land use decision
process, as demanded by Agenda 21 [16].
