== RenewGrass ==

RenewGrass is a plug-in in the (Reference Net Workshop) Renew.
Its main functionality is the invocation of Grass GIS commands from Petri nets transitions. 
The objective of RenewGrass is to allow modeling, implementation and execution of image processing workflows using Reference nets. 


== Use Case: Computation of the Nomalized Differences Vegetation Index (NDVI)

After the simulation of the above net, we get the NDVI of a satellite image that we can also display using the Grass commands (d.mon and d.leg.rast).
