Vertical Datum NADV88

Brian Harvey

Client is asking for the DSM to be in NAD88. I suspect they want the vertical datum which I understand to be known as NADV88. At what point and or how do we export using this vertical datum as there is none showing in the drop down box. Any help on this would be appreciated. Maybe the end user has to use features in say ARCGIS ( they have this ).

Brian,

There isn't currently a way to automatically convert vertical datums in Global Mapper. However we are preparing to release Global Mapper v15 which will have a Global Energy Mapper module that allows for vertical datum conversions if you also have Blue Marble's Geographic Calculator product installed. With that enabled you could select the source and output vertical datum for exports. Please contact gmorders@bluemarblegeo.com for information about the upcoming release and getting the needed Geographic Calculator software as well.

Thanks,
