Why are there some errors and inaccuracies in the transformation between geodetic systems?
I want to know the reason why the transformation between geodetic systems might result in some inaccuracies and how I can minimize them.
A more specific question might get a better answer. What systems for example, what tools doing the transformation, and inaccuracies measured against what?
In an unchanging world with perfect data and modeling maybe you could approach your goal. More so over a small area.
For information about how and why at the highest levels such transformations are created.
As for as “inaccuracies” consider the magnitudes of the changes shown below:
Each successive realization includes measurements that were not yet made when the previous realization was computed, and reweights or excludes altogether outlier measurements that were used. Different input data means shifts that are not uniform throughout the network.
This kind of sums it up....the earth with no water looks like this....
This is the abridged reader digest clipped paragraph version to be sure...
