Using QGIS: From a set of points, I would like to interpolate the change on the Z-axis when moving from one point to then next over an area, with a resulting raster of a resolution of 1x1m. I would then like to use an equation calculate a value between each cell and its surrounding neighbors.

Could anyone briefly explain or nudge me in the direction of a post on a similar matter?

  • Are you asking how to interpolate a DEM from gives heigth values?

  • Yes, I guess. Like using IDW or any other method would be nice. A key point is to be able to apply the equations afterwards. Apr 11, 2023 at 10:45
  • So, what keeps you from running IDW?

  • Nothing, except I never have done it. I guess my question comes back to if it's possible to do this by adding subsequent calculations like I mentioned. Because I really don't want to spend time in learning how to IDW in QGIS if I'm not able to do what I ultimately sent out to do. Apr 11, 2023 at 11:32

    Can you give an example of an equation you would like to apply?
