[GRASS-user] stvds

[Ivan Marchesini]

Thank you for your answer Veronica,

in the meantime I found an addons that does exactly what I need: sample 
a strds at specific point in space and time defined by means of a point 
vector layer having an attribute column with dates (tool prepared by 
@Luca Delucchi: thank you)

I put the link here for anyone that in the future may have a similar 
problem:

thank you again

Ivan
