• Potentials corresponding to this first step (Markov Model)
• 2nd Step : Network segmentation
• 3rd Step : 1D features matching
• 4th Step : Results analysis
• Validation criterion
• Suppressing ambiguïties, matches validation and interpretation
• Matching of satellite and cartographic data
• Results
