Elimination of objects in any database must be based on their earlier sorting. This is one of numerous problems we come across during the process of digital generalization of objects. Obtaining a clear classification of objects usually leads to too extensive development of the domain of descriptive attributes. The author tries to prove that it is useful to make structural regions for the network of linear objects such as roads, rivers or railways for the classification of objects, using the smallest number of attributes. The created classification allows automatic elimination of the network objects. To illustrate the mentioned above issues a fragment of a topographic database was selected. It was the layer of the road network. In the paper, the problem of necessary conditions to form regions is also presented as well as the way of classification of created regions. After making the classification of structural regions of the road network, the process of automatic elimination of regions is presented. It is made by the aggregation with one of the neighboring regions. Elimination through aggregation is based on fully automatic processes and verifiable values of attributes. The carried out process is independent from the situation of objects and the applied software, although it requires application of the accepted model of data.
