Spatial data infrastructures play a key role in coastal management decision making in the Seychelles.
This paper describes four components of a web-based spatial data infrastructure that were developed to
facilitate coastal management of the Amirante Islands in the Seychelles. The four components include: (i)
the institutional arrangement for using spatial data effectively to address local management challenges,
(ii) the production of island habitat maps from remotely sensed data, (iii) the tasks undertaken for promoting
access to and use of this spatial data, and (iv) an example of how this data is used for a specific
coastal management application in the Seychelles. By outlining these four components, the value of this
spatial data infrastructure framework for tropical coastal management in the Seychelles is demonstrated.
