Abstract
The aim of the paper is to show how to extend the database of topographic objects for the purposes of automatic data generalization. Generalization is performed basing on topographic databases, that exist in various scales (BDOT10K - scale 1:10 000, BDOO - general geographic objects database 1:100000). Under the law, these databases are fundamental source of information about the spatial location and characteristics of topographic objects in Poland. BDOT is a multi-resolution database, which is fed by the objects with varying degrees of details and accuracy, depending on the data source. It is also assumed that the BDOT will be a source of data for the editorial of standard cartographic studies for various scales. Objects for a given scale are obtained by the generalization processes, which allow to generate less detailed data (for example, in a scale of 1:50 000) from the reference dataset (scale 1:10 000). The authors have proposed the structure of MRDB system, which assumes the existence of Web Generalization Services (WGS). These services can provide a remote access to simplification algorithms and the data generalization "on the fly" [5, 4]. It can significantly reduce the process of data producing through automation of the manual work, resulting in a significant optimization of the database at the level of its power. Therefore, we can observe the optimization of the work with databases, already at the level of their feeding.
