Typically, the geospatial information processing (coordinate data area symbols, character and quantitative attributes) in the vector or raster models is to be complemented in accordance with the relations and connections between objects. However, the models do not support the full set of operations required for topological relations registration and filing. To add functionality to the geoinformation systems there has been developed the multilayer object representation model. It includes vector primitives for description of objects and the relations between them. These relations are defined in the form of graphs. This feature makes it possible to get more detailed information and to computerize the computation process of retrieval and control of topological relations and connections between objects. ER -
