Figure 1 : GIS method in Arcgis using default functionalities of ArcToolbox and additional tools
(extensions and scripts). In part A, we give the most important steps of the Mapedge method on small
image composed with 2 woodlots. In step 1, input data come from supervised classification of satellite
images (SPOT 5). In step 2, we used GUIDOS tool to make MPSA (Morphological Spatial Pattern
Analysis). In step 3, we combine the 2 raster layers and convert to vector data and generalize to simplify
features. In step4, we check direction of vertices and label them. In step 5, we create transect features
from rotation of vertices and use them to calculate edge descriptors (about interface with adjacent land
cover; about topography with Digital Elevation Model and orientation). We will apply the same method
at landscape level (several hundred polygons of woodlots) and transfer output results to statistical
analyses. In Part B, we give legend of symbols.
