What data sources do you work with? I didn't know about RTK, it looks interesting but seems hardly applicable to satellite imagery, since it seems that you'd need a lot of receiving stations on the ground?
My understanding is that providers like Maxar report coordinate systems correctly, but that errors in ortho-rectification (due to imprecise or wrong terrain altitude data) make it hard to make two images of the same area match exactly.
> even using advanced systems from leading suppliers, vital facts are just not recorded because geographic coordinates system are so numerous and complex suppliers just offer defaults and do the real work in the background
Not sure I understand what you mean by this. Do you get data that reports a coordinate system different from the one it actually uses?
