Definition of land cover classes
Before starting to map land cover classes using Sentinel-2 satellite images we need clear definitions and a classification scheme.
An example of a hierarchical land use and land cover classification scheme is the European Urban Atlas.
The scheme defines 5 main meta-classes where the class 1. Artificial surfaces has many sub classes as shown in the following figure.
On the lowest classification not all classes defined in the European Urban Atlas appear in the surroundings of Göttingen:
The specification other metaclasses is not as detailed. If we are more interested in forest and open area classes we need to adapt and modify this scheme.
