I don't know if "ground plan based" is the right word in the following context:
A computer program reads a ground plan and produces a result ground plan. The result groundplan's deviation from the input ground plan must be within a prescribed tolerance to be called "ground plan based".
Possible words for this situation might be:
ground plan based, topographic planimetry, planimetric reconstruction
But I'm not sure which is the common word? Which word would you use to describe that both of the ground plans match nearly 100%?
