Distortion characterization Q is calculated as a ratio of the area with acceptable distortion in the map to the Earth surface. The sequence of 100 projections arranged by Q where area distortion limit is Kmax = 1,5 Kmin and angular distortion limit 2ωmax = 40°, was published by Čapek (1997). In this paper 25 different combinations of distortion limits are used for deriving Q. New 25 sequences of Eckert's projections are analysed afterwards.
