The quality of submitted models is measured per dataset in terms of completeness, correctness and accuracy only for wall elements. To see the results for each dataset click the dataset name.

Completeness is defined as the area of intersection between the source and reference surfaces for a buffer size b over the total area of reference surfaces.

Correctness is defined as the area of intersection between the source and reference surfaces for a buffer size b over the total area of source surfaces.

Accuracy is measured as the median absolute distance between sample points on the reference surfaces and the closest surface in the source model as a function of a cut-off distance r. Lower values represent higher accuracies.

A more detailed description of the quality measures can be found in this paper and this paper.

The tables show the measures for b = 10 cm and r = 10 cm. The figures show the measures across a range of b and r from 0 to 15 cm. To see the full resolution figures click the corresponding image.
