Vertical Datum Shift

Edit menu choice with a DEM as the current map.

• You can shift between the WGS84 ellipsoid, and the EGM2008 geoid.  The shift file from NGA must be available in  C:\mapdata\geology\geology_grids
• If you want to use another file for the shift, you must insure that MICRODEM cannot find the EGM2008 shift local (don't download, move, or rename), and identify it yourself.
• This creates a new DEM, but does not automatically save it.  The new DEM's name indicates that a vertical datum shift was done.
