Hi list -<br>
<br>
I have a question regarding transformation of ellisoid heights to
geoid heights..<br>
<br>
I have a dataset consisting of points, where the z coordinate is a
attribute column for the layer. (If necessary, this can be changed
to a 3 dimensional layer type - or the x, y values can be placed i
2 attribute columns - whatever)<br>
<br>
The data is in EPSG:32825 (UTM32N/ETRS89) and the present height
values are ellisoid height values for this CRS.<br>
<br>
I would like to transform the height values the the corresponding
DVR90 ( EPSG:5799) geoid height values<br>
<br>
Can this be done in QGIS using some kind of expression function.
Or using ogr2ogr ? or Postgis ??<br>
<br>
