Kolloquium Geoinformatik Topological Analysis of Landscape Structure using Graph Theory

System behaviours of juxtaposed landscape elements can be revealed by analysing compositional and configurational properties of a landscape. In this research, spatial relationships in the form of spatial topology are exploited to provide insights on the configurational properties of landscape elements through time and space. For this purpose, a graph-based data structure named Spatial Temporal Relational Graph (STRG) is created, and a set of associated graph analytical tools are adapted for STRG. By analysing the relational dynamics of landscape elements through time, the result shows that the combination of graph analytics and spatial statistics provides clear indication on phenomena suggested by landscape ecology theories such as ecotones, land degradation by perforation and evidence of hemeroby.
