How the cell size' limits are set in an IDW interpolation?

  • 1.  How the cell size' limits are set in an IDW interpolation?

    Hello,

    I have been trying to find information about how the cell size's limits for a Thematic Map using IDW interpolation are set. I have a lat/long points map and I am doing a thematic map based on grids using IDW interpolation, when playing around with the cell size of the grids sometimes it shows a message that the cell size I am using is below the minimum allowed or above the maximum. I am wondering how MapInfo Pro determines those values.

    Thanks in advance.

    I can't give you any information that relates specifically to your question, but you might be interested in a couple of articles I posted on gridding.
    Both are called "What gridding method should I use...?" - links are below.
