Global Mapper v25.0

Possibility of saving attribute calculation formula


It would be fantastic if we could save custom formulas in the attribute calculator so we could use it in other projects.

Saving/Loading the formula would be fine but it would be even better if we could add custom formulas to the "Available functions" in the calculator.

Best regards

    Hi Michele,

    Yes, looks like about the best you can do right now (as of GM 24, that is) is to copy a formula from the Attribute Calculator dialog and store it off to the side, like in a separate text file. I can see that this could be a useful addition.

    It would be possible to persist successfully run formulas to a central location (like the Windows registry) and then made retrievable for other projects, but there would need to be some UI and other work required to manage those persisted formulas, probably in a separate dialog available from the Attribute Calculator, though accessible from it.



  • Dear Jeff,

    Thank you for the reply.

    It looks like adding new functions to the defaults ones would require quite a lot of work so, for the time being, it could be good enough to have a save/load option like for styles.

    Best regards
