Landslides are an important landscape problem in the Carpathian part of the Czech Republic. In order to establish which slopes are most at risk, their spatial incidence can be modelled using techniques of geographical information systems together with a database describing past landslides. Three modelling strategies - rule-based modelling, ordinal modelling and categorical data modelling - are adopted and compared. It is suggested that the categorical data modelling approach is the most general and makes the best use of the available information.
