Hello André, I wonder if you successfuly found a way to achieve what you were talking in this post. Actually, I am looking for something similar. Instead of uploading .csv my app would allow users to upload shapefile. I am reading about dynamic models but the doc is scarce. If you can share a bit of what you have learnt that would be much appreciated.
