Description: The approaches to the creation of an information technology an estimation of object. Presented information technology an estimation of spatially distributed objects on the basis of a formal model and describing structure of model. Presented building a network model and describing the transition matrix and initial marking. The analyzed of network model with subsequent modification processes. Presented strategy of solving the problem and describes the practical implementation of technology an estimation of object as an example of land.
Keywords: information technology, network model, estimation the conditions, the spatially-distributed objects, modification, GIS-technology
