Hello Michele,

There is an interesting paper about this problem :
<http://www.geocomputation.org/1999/082/gc_082.htm>

I don't know if there are libraries implementing these algorithms for 
DEM interpolation. Does anybody know if there is an open source function 
to compute the coefficients of a bicubic interpolation ?
