14. Conclusions Lots of information available
Primary land survey information, as well as baseline terrain and geophysical information
Secondary infrastructural and social data
Multi-scale contextualization
Scenario-building possibilities
Climate change is inevitable; adaptation and mitigation is key
GIS is tool
