  • 1.  Update column using mrr raster

    Posted 02-09-2021 11:02
    Hi, I'm trying to update a column using a .mrr raster file.  Under the 'update column' function this doesn't seem possible.  Is there a way around this?
    Any help would be hugely appreciated, thanks

    Simon,

    Have you tried "Point Inspect" tool in Raster Operations?

    Thanks Andrei
    I don't think that would work in my specific case as I don't have a list of points to assign the required info to?  I need to add to a table of polygons, an average value based on all the data within each polygon.  The target data is stored as a .mrr raster file.  I have tried exporting the raster into a txt file which will work, but the text file produced is over 12GB which makes it unusable!

    Hi Simon,

    In this case you should try Region Statistics tool. It would not update column in your original data, but would output statistics for each of the polygon into a separate table and you can use it to update your original table.

    Hope it works for you.
