I am working on calculating a slope raster in Mapinfo using a 15cm DEM derived from a LiDAR point cloud and the output data will have 3 predefined breaks displayed so I need to blur those relatively small areas across a larger DEM area fairly accurately.
I've read about tools which use FFT or Gaussian Blur but can't find anything for Mapinfo (64 bit). Can anyone suggest a tool or command that can be used?
edit from comments:
I need to modify the 50cm pixels from their existing value to a value based on a number of surrounding pixels to generalise the slope. I believe this could be achieved using Fast Furier Transform or a Gaussian blur algorithm but I am not aware of which tools/commands to use in Mapinfo 64bit to accomplish this.
