I hope that this is the right Stack Exchange for this question. I may be oversimplifying this, but I'm looking for verification in my understanding of the following:
If I have a spatial dataset in 2 different data [datums], the coordinates [absolute location] of the "same" point may differ between the two data. This magnitude will depend on the geometric difference between the datum ellipsoids at the location of my point.
If I have a spatial datasets with the same datum but in 2 different projections, the coordinates of the "same" point will be identical, but the distance/shape of path/direction between this and another point may vary between the two projections, due to distortions introduced during the projection process. The type and degree of this distortion depends on the projection used and where it lies tangent to the datum ellipsoid.
Is this an acceptable degree of simplification to constitute a "strong understanding" of the topic? Or am I way off and conceptualizing this incorrectly?
