1. LUMASS
a Spatial System Dynamics Modelling Framework
Alexander Herzig and Daniel Rutledge

2. Land-Use Management Support
How does the system work?
How does the system react to management?
Spatially explicit system dynamics modelling
 System understanding
 Impact assessment
What do we do?
Where do we do it?
Spatial optimisation
 Land-use development scenarios
 Resource-use efficiency

3. Design Criteria
 Raster-based (attribute table support)
 Large data support
 Multi-scale (space and time)
 Dynamic models
 Component-based
 Easy to use for non-programmers

4. LUMASS Features
• Multi-dimensional data support
• Legacy model integration
• Cellular automata modelling
• Spatial Optimisation
• SQL processing
• Visual programming environment
• Auto-completion
