Geotechnical engineers need access to the best scientific data available that describe the geological environment and processes in it. This article describes the development of conceptual model of geological environment in landslide areas. Landslide areas are environments where the interests of science and society meet. Numerical modelling of various phenomena in anisotropic conditions may require the spatial interpolation of scattered measurements in order to obtain values at computational mesh nodes. This paper examines the various spatial interpolation methods and gives overview on transformation process by preparing conceptual model of the geological environment.
