Ginzburg IV projection, which is also known as the CNIIGAiK 1939-1949 projection, is a modified polyconic projection that was preferred in the old USSR for mapping the whole world. There exist no mathematical equations which define the projection. In the Russian literature, the plane coordinates belonging to a given geographical latitude and longitude are given on tables in 10degrees interval. In this study the fuzzy logic method is suggested for modelling geographical grids which are defined only with tabular coordinates, such as in the Ginzburg IV projection.
