The problem of synthesis of the geographical information from various sources becomes one of the most actual in procedures of geoinformation mapping and modelling. Quantitative synthesis of remote and natural data is important as at making of universal landscape maps and landscape GIS, maps and GIS division into districts of territories, and at use of the generated databases at creation of derivative estimating maps.

The main question is objectification of mappings and calculations that means transition to universal models of transformation of the geographical information. The models reflect potentially different aspects of existence of geosystems and their space-time interaction. The existence of the mathematical equations which in corresponding system interpretation generate models of geoinformation synthesis at solving problems caused by queries with a complex configuration of the subject matter is supposed in a context of mathematical technologies for GIS-mapping.

Such complexity of query is characteristic for the formulation of geographical problems when it is necessary to consider the facts of a geographical position, feature of territories and property of the objects situated there, and also variety of estimated and mapped qualities. For example, to estimate an abundance of individuals of some biological species in concrete landscape position in the preset territory. Similar problems for a long time are solved by experts, but schemes of the decision should be realized and presented in the form of some computational model.

It is clear, a framework of geoinformation synthesis is the models based on knowledge, i.e. it formalizes real information processes in the nature and a society. Some ways for universalization of modelling are considered through creation: 1) polysystems of mutually interpreted models; 2) multimodels as functional set for mathematical presentation of different knowledge; 3) polymodels as weighed sum of special models of various system type; 4) universal mathematical models of interaction; 5) universal models of concretization of knowledge.

At realization of the planned research directions it is necessary to ascertain uniqueness of statement of each problem of geoinformation synthesis. The specificity of geographical knowledge that naturally realized at problem-, object - and subject-oriented modelling using bases of spatial data and knowledge takes in account. Thus, modern development of geoinformation technologies occurs in movement between uniqueness of statement of problems and universality of their decision. The illustrations of geoinformation synthetic and estimating mapping by differentiation and multiplication of geographical data and knowledge from various sources are considered at carrying out of interdisciplinary researches.
