Task is to project a DEM from ETRS_1989_UTM_Zone_30N to WGS 84 / UTM zone 29N. Easy enough right? Process succeeds, but inaccurately.
Some LAEA data uses a sphere rather than an ellipsoid/spheroid which if the metadata isn't correct can cause problems when the data is reprojected.
I tried to redefine the projection from ETRS to LAEA like the link above states. No luck.
