A quantitative comparison of legends between Belgium and neighbouring countries as a starting point for an objective generalization

摘要

For the comparison we started from the legend, but there are also elements in the map that are not present in the legend. This study can therefore be considered as a possible approach of map object classes selection for generalization. The amount of elements depends on the geographical characteristics of the area. The legend gives an idea of the map image output and it will proportionally change with the contents of the map. A statistical approach is a handy help for selecting and eliminating map objects.
