Modeling Land Change using One or Two Time Points based Calibration - A Comparison of Factors

Abstract

One of land change model parameters in calibration step relates to how changes over time and space are considered in the model. A land change model can be calibrated with the state at one time point or with the difference between two time points. The purpose is describing land use and cover (LUC) state patterns, i.e. one time point calibration, and LUC transition patterns, i.e. two time points. For a case study in Spain we obtained the collections of factors for two calibration periods at one time point (dates 2000 and 2006) and the collections of factors for two calibration periods between two time points (periods 1990-2000 and 2000-2006). Evidence likelihood is used to transform the explanatory variables into factors. The objective of this paper is to compare these four collections of factors to show how the choice of reference maps influences the factors and how these factors highlight the change patterns in two different calibration periods and in the calibration of two models. As a following step the detailed results for the different factors and LUC categories are analysed.
