projection file - AGD66 EPSG20255 + AHD heights
« on: March 26, 2019, 07:13:59 AM »
hi team,

we have some equipment that exports either WGS84 lat/long and ellipsoid heights, or WGS84 lat/long and AHD heights.

we are having alot of trouble coordinating the Z value of the projects due to incorrect height transformation.

is it possible to be supplied with a WGS84 projection file with AHD as the vertical datum?

Using the standard wgs84 to convert the ellipsoid heights isnt accurate due to a local datum being used.

thanks!
