RSopen (RuimteScanner 2.0)

This wiki is the technical reference of RSopen, the open-source version of the RuimteScanner 2.0 model. It describes the methods, procedures, assumptions and design choices of the model. The text in Part I is broadly based on the system description Koomen, Rijken and Claassens (2024). The model is under active development, and these pages are therefore updated continuously with the latest model code and insights.

Ten pages have an English translation. The other pages are in Dutch; links to them carry "(in Dutch)". The Dutch pages are leading. The glossary at the bottom of this page gives the English terms used for the Dutch model concepts.

Part I: What is the model?

• Introduction: history, purpose and positioning of the RuimteScanner
• Model structure overview: the three-layer model, hybrid allocation, synthesis
• Scope of application: what you can and cannot do with the model
• Why GeoDMS (in Dutch): what the GeoDMS platform brings to the model

Part II: How does the model work?

This part describes the workings of the model in detail: from building the initial situation, through determining availability, suitability and density, to the final allocation and the results.

Preparation

• Time dynamics: base year, projection years, path dependence, sequences and iterations
• Initial state (base year) (in Dutch): built from the BAG, LISA and other registers; this is phase 1 of the four
  • BAG processing (in Dutch): from the national delivery to the states per cell
    • VolledigeBAG (in Dutch): the BAG with all occurrences of buildings and addressable objects, from the stores of BAG-Tools
    • BAG statuses and stock (in Dutch): which status counts when
  • BAG new construction in detail (in Dutch): including recent developments in the first projection year

Phases two to four, before allocation

• Availability: restrictions, stimuli, sieve analysis, planning capacity and evidently in use
  • Restrictions (in Dutch)
  • Planning capacity (in Dutch)
• Suitability: empirical component, design component and the rung concept
  • Hedonic house price model (in Dutch): the price function behind acquisition costs, revenues from new construction and dwelling value indicators
  • Redevelopment probability (in Dutch): which parcels with dwellings are due for demolition and new construction in a projection year
  • Rungs (in Dutch): the ladder: axes, ladders per sector, and which axes move with time
• Density: dwelling density, job density, energy density and density factors

Allocation

• Allocation procedure in formulas (in Dutch): the formal description of the allocation process
  • Overflow (in Dutch): what happens when regional claims do not fit locally
  • Housing elaboration (in Dutch)
  • Employment elaboration (in Dutch)
  • Other sectors elaboration (in Dutch): solar, wind and holiday accommodation
  • Water storage elaboration (in Dutch): the sector that designates areas to retain water
  • Nature elaboration (in Dutch): new nature from maps that are imposed per variant
  • Agriculture elaboration (in Dutch)
    • Drought damage and wetness damage (in Dutch)
    • Salinisation and salt damage (in Dutch)

Results

• Land-use map (in Dutch): dominance rule and aggregation into an integrated map
  • Land-use state register (in Dutch): per cell a type and a year of change, the basis for the vegetation-dependent indicators
  • Classes of the land-use map (in Dutch): the classes of the map: sectors by sealing, nature by management type, agriculture by type, and the main classes of the map image
• Impact modules and indicators: the index of all indicators, from land use and agriculture to climate, water, soil and health

Part III: Applications

• Scenarios and policy variants: the structure of scenarios and variants in the model
• Application: NL2120 (in Dutch): water and soil as guiding principles, four variants, projection years up to 2120
• Application: Ruimtelijke Verkenningen 2023 (in Dutch)
• Pilot application: Ruimtelijke Verkenning Friesland 2024 (in Dutch)
• Other applications (in Dutch)

Part IV: Other

• Installation tutorial (in Dutch)
• Software and data elements of the model (in Dutch)
• Running a batch run (in Dutch): running a production run and a delivery with the scripts in batch
• Production profiles (in Dutch): which indicator domains a project line delivers and which state the preflight expects
• Decoupled files (in Dutch): which intermediate results are stored as files on disk, and how the fingerprint guards that they are still valid
• Engine test (in Dutch): running two commits of a branch under the same profile and comparing the outcome: baseline, test profile, chain of groups of commits, report
• References (in Dutch)

Glossary
