Polygonal meshes are the most common way of representing 2D geometries for simulation purposes. Integrating simulation to a GIS requires storing georeferenced meshes in a databases (or using standard SIG file formats), and being able to use simulation values interpolated over the elements as a map layer.
This presentation reviews what is the closest you can get with existing FOSS GIS solutions and what is needed to bridge the gap, both on the simulation side and on the GIS side.
We show the few lines that need to be added to the simulation code to read a mesh from the GIS and write the results to the GIS. We also present a prototype mesh layer for QGIS that has been implemented as a PluginLayer.
