Suitability (aka Transition Potential, utility, or land use value) is a combination of factors that express the added value of allocating a resource to a purpose.


In the context of GeoDms applications,

  • resources are usually Land Units, often organised as a grid of raster-cells.
  • purposes are usually Land Use Types
  • the added value is expressed as:
  1. Ratio (which relates to the use of the pseudonym Transition Potential) or
  2. Monetary unit of Yield per [Land Unit]] or area per unit of duration (say: [EUR*m^-2*year^-1]) or
  3. the capitalized value thereof (say: [EUR*m^-2]).
  • Suitability is operationalized as a set of value maps, one for each Land Use Type.

Common Factors of Suitability are:

  • Physical factors, such as soil type that determine the annual yield of specific production plans.
  • Locational factors (usually taken as positive, representing interaction value, although a more physical interpretation related to negative costs of transportation and travel would make sense too).
  • Transition Costs of destruction and reconstruction (usually represted as one time costs, which forces a modeler to think on Annualisation or Capitalisation)
  • Location specific subsidies and/or taxes
  • Spatial Planning Restrictions (sometimes taken separately in Allow maps).
  • Physical restrictions on transition (which are sometimes time dependent).
