I've got a lot of points with Z-values, where I would like to construct their extent using IDW (or similar). I would like to see their extent inside my buffer, is this possible or is the tool not designed to move beyond/behind the last/first point? See picture for explanation, I can use the buffer to cut the one in shown when running the algorithm, but can't get the extent quite right.
The points are spaced approx 10 m from each other, the buffer is 50 meters from centerline.
I've got access to 3d analyst, spatial analyst and arcgis advanced desktop.
