RESUMO

: Governmental, corporative and scientific institutions have carried through great investments in the generation, processing and distribution of remote sensing images. This context has caused an explosive growth in the repositories of images of these institutions, surpassing the current capacity to interpret and to analyze these data. Parallel to this growth a new technological platform has appeared, the Web Services which is seen today as being the next wave to the evolution of the Internet. The vision is to open for the provision of available processing services in the Web that would allow any user, anywhere to execute a established procedure over a chosen remote sensing images stored in an repository. That shall increases the current capacity to interpret and to analyze these type of data, reducing costs and speeding decision processes. This work considers a specification for a new geographic service, the WISS - Web Image Segmentation Service - which is compliant with the proposals presented for the OWS Framework, in its version 0.1.3 presented by the OGC trust. An implementation of the specification WISS proposed that uses the open source library of geographic components - TerraLib, and a demonstrative prototype was implemented for the specified service. Finally, a discussion on the use of the specifications of Web Services is made in the context of the OGC and its limitations for applications that operate on large remote sensing image databases.
