**Categorization of Multivariate Map Symbols (CMMS) method V1:**
- First method draft appeared in Diploma theses (Knedlová, 2016; Trnková, 2017; Lacko, 2018) supervised by Čeněk Šašinka and Zdeněk Stachoň.
- The CMMS V1 was created on the basis of those theses and it was published in english (see **Lacko, Šašinka, Čeněk, Stachoň & Lu, 2020**).
- The CMMS V1 contains 20 cartographic maps used in open-ended format.
**Categorization of Multivariate Map Symbols (CMMS) method V2:**
- The CMMS V2 is improved CMMS V1.
- The CMMS V2 contains 10 original maps with highest DIF and without any cross-areas used in open-ended format (i.e., subtest 1).
- Moreover, it contains 10 new maps which are used in forced-choice format (i.e., subtest 2).
- The CMMS V2 is currently used in the follow-up eye-tracking study.
