From Mathematical Morphology to Morphological Terrain Features

Mathematical morphology is a theory for the analysis of spatial structures based on set operations such as the union, intersection, and complementation. In practice, the analysis is performed on digital grey tone images. Indeed, any grey tone image can be represented as a 3-dimensional set having the image definition domain as basis and a height proportional to the grey tone intensity level of each pixel. It follows that mathematical morphology is naturally suited to the analysis of actual digital elevation models. In this chapter, we provide a brief introduction to morphological operators and show how to combine them for extracting terrain features. The described methodologies have enabled the development of the pan-European catchment and river database detailed in this volume.
