Hi, I've got problem with coordinate system (Kertau RSO: EPSG 3168). The potential position (yellow icon) is far away (approx 50 meters) from actual coordinates (blue icon) on ground.
It also happen for coordinate system GDM2000 / Selangor Grid (EPSG:3380).
Anyone can help me for this?
It could be because of wrong GPS altitudes. What device was used to capture photos and from where are positions?
