Hello there! I was wondering wether there was a simple way of setting all the values (of a grid) inside a certain polygon to a set value. A typical example would be to have the topographic surface including the sea and a few lakes not far off. Each of these water surfaces should be at a certain (flat) level. Interpolation won't give me constant values inside the polygon even if I add many values inside. If I realize a blanking procedure and then replace the blanking values with the water surface, it will be difficult to diffentiate one water level from another. Thank you for your suggestions Best regards Thierry
