Use white space deliberately to separate distinct geological units while maintaining an 80:20 ratio between map content and supporting elements.
Scale and Proportion
Adjust feature sizes and symbol weights based on their geological significance. Make dominant formations occupy 60-70% of the map area while smaller units receive proportional representation. Scale your symbols consistently with a 3:1 ratio between major and minor geological features. Use a standardized progression of line weights ranging from 0.1mm for minor faults to 0.5mm for major structural boundaries.
Visual Flow and Movement
Guide the viewer’s eye through your map using directional elements like fault lines and formation boundaries. Create visual hierarchy by varying line weights with thicker lines (0.35-0.5mm) for primary features and thinner ones (0.15-0.25mm) for secondary details. Use arrow symbols and graduated colors to indicate geological processes or structural trends. Position labels to follow natural feature orientations enhancing the map’s dynamic flow.
