Hi,

I have two adjacent DEMs with different projections (see attached)
I suspect the difference will be minimal but has anyone have an idea to the scale of the difference?
i.e. Should I be concerned?

They're the same. My guess is that the GDA_1994_Transverse_Mercator DEM is a GRID or originally came from a GRID/TIN. That file format used the ArcInfo Workstation coordinate system format. It doesn't support as much as the ArcGIS format does.
