I created a raster from contour lines. The contour has a 2 M resolution and I set the cell size to 5. Increasing the cell size is not an option and I may even run it again on a smaller scale. I have a lot of cells that did not have a contour line pass through them so they came up as no data. What tool should I use to give these cells an elevation that is either equal to the closest polyline or even better, a distance weighted value between two cells that have a value. I like the ideas of interpolation with IDW, nat neighbor, and kriging, but they work for point values. Is there a better way than transforming my cells to points, then interpolating, and then changing them back with values?
