Map Presentation Recommendations

  • Equal-area map projections for international and global maps (van der Grinten or Goode’s Interrupted Homolographic preferred);

  • Coloured surface maps, based on interpolated and smoothed data, are most effective for conveying information.


It is strongly recommended to follow the map presentation used by the FOREGS Geochemical Atlas of Europe project, where interpolated smoothed colour surfaces are displayed together with proportional size dots (see example below):
