Résumé
A key motivation of this master thesis is to investigate how it is possible for the organizations and/or individuauals who does not have access to pripiotry softwares to use specific workflows. The workflow used, is the ‘forest fire danger assessment integrating drought information‘. This workflow can help organizations, which are trying to model forest fire danger in the areas prone to forest fire. In the existing models, long-term drought information is not considered. The idea is to check if this parameter can contribute to the current models. The results show longterm drought information can be used as a complemenry information, and it can add valuable information in particular outside the fire season. To transfer the operations from ArcPy, which the original workflow is based on, to other open-source libraries such as PyGrass as one the most powerful spatial libraries, WPS profile is used. WPS profile is an approach for geoprocessing operation description, which uses hierarchical structure of concept, generic and implementation levels. These different granularity levels provide a framework for comparison of semantic and syntactic properties of the operations. The results show although, WPS profiles can help for this comarison, it still has some deficiencies regarding standards. This issue causes the operation descriptions not to be fully understandable and comparable for the user.
