Hi,

Does anybody know a trick to make negative elevations values positive within TBC? Could either be for points or for a surface model. e.g. an elevation of -100.123 becomes 100.123.

I think you're looking at an export to a spreadsheet, where formulas would handle it, and re-import the data -  or have a TML built.

What's the application?

Thanks Nelson. Excel will do it. I need to get more info on this, but relates to bathymetric data. It might not need doing now.
