Abstract
A geological fund may contain data from various sources that describe the same object, as well as from other arrays of information. Correct use of the fund data is secured by harmonization of the information. For effective functioning and satisfactory information service, a geological fund should be not only a library of digital data with information search but also a system of content-related information processing. A knowledge base in an information system is an integral part of a model of the surrounding world, which includes rules, algorithms, and their parameters that can be applied to the content of the database of the factual data on a subject area to solve special problems. This article discusses the concept of a knowledge base of a geological fund, its tasks, and ways of its organization and use. Two problems are considered in detail: control of information consistency and updating of derived data, particularly synthetic maps. A geodatabase of a project of large-scale geological mapping of Moscow, which contains over 90 000 drill logs of exploratory wells and digital map data of a structural-geodynamic map, four geological maps of various stratigraphic divisions, a hydrogeological map, and five synthetic maps of dangerous processes and engineering–geological zonation, is selected as an example.
