RenewGrass - A Tool for Building Scientific Workflows: Application to the Remote Sensing Domain

In this paper, we present the implementation and the integration of an image processing tool named RenewGrass. It is integrated in Renew, which is a powerful modeling editor and simulator of Petri nets, especially reference nets. The objective of this work is to allow Petri net-based modeling and execution of image processing workflows with more ease and transparency. Additionally, RenewGrass has been employed to specify, implement and enact workflows from the remote sensing domain. We specifically focus on the computation of vegetation indices corresponding to satellite imagery. The first evaluations show that our contribution permits to reduce the gap between modeling and implementation of image processing workflows. Moreover, the deployment of RenewGrass into a Cloud environment is also discussed at the end of the paper.
