Is it possible to access z-values on a height map on a pixel by pixel basis using scripting?

I have a terrain height map loaded in, and I have some math formulas I'd like to apply to it (to alter it for a game level environment) is it possible for me to use the scripting capability in GM and read, manipulate and write back modified height values at pixel level.

You would need to use Python scripting to get access at the pixel level as the traditional GM scripting does support that type of access. You can run Python scripts right in the GM Script Editor.

See https://www.bluemarblegeo.com/knowledgebase/global-mapper-python/Reference.html#raster-elevation-layer-query-functions for the GetPixelElevation / GetLocationElevation functions in GM Python to get at individual pixel values.

Thanks Mike, I will give that a try.
