Other DEM file format ?

Hmmm...

I've also a stupid question : why some institutes sends lot of money to produce DEM at 1m if a simple linear interpolation is enough... ?

So... let's forget... it was just a suggestion... some apps can read multiple DEM file formats, RC can't, no problem in fact, it's like that.

Best regards,
