How set theory and interval distances can be combined to compare qualitative concepts defined on reference systems at different levels of granularity is studied in this paper. A measure of similarity to compare qualitative concepts and reference systems is presented and implemented using first order logics. A case study with different angle descriptors is used for testing and promising results are obtained.
