Find Extreme (Min/Max) Elevations - Is this available/doable via scripting

Hi all,

I have around 5000 GeoTiffs that I need to find the minimum elevation value for and store in a txt file.
Can you run Find Extreme (Min/max) Elevations via a script as this is does exactly what I need?

Any help would be much appreciated
Kind Regards

    Howdy,

    I think the metadata that can be saved from the QUERY_LAYER_METADATA script command should contain that information.  There is a simple sample script in the scripting reference that you can start with and modify as needed.

    Good luck,

    Mark

    Thanks for the reply Mark,

    Oddly the min and max value in the metadata is different to the max and min obtained from running Find Extreme (Min/max) Elevations. I'm running v15 of GM so maybe this was a bug.

    I luckily don't need to do this anymore as I do it in another program.

    I think it would be useful to have this feature accessible via script, especially when you have to do it on hundreds of layer/files.

    Ill mark your reply as the answer as it pretty much answered and gave an alternative.
