Height difference when raster transformation
« on: October 07, 2019, 03:45:48 PM »
Hello
I have a project prepared in modern Polish Coordinate System (EPSG 2176), height Kronstad. I would like to export DEM to an old coordinate system (ESPG 2174) with the same height system. Unfortunately the height difference between rasters is around 40m.

In attachements two dems form the same project.
What could be the cause and how can I work it out?

Hello Damian,

The systems EPSG::2174 and EPSG::2174 seems to be based on different datums, so the altitude difference is expected.
