The article describes the experience of creating a geodatabase of the melioration system of the Kaliningrad region for integration into an agriculture management automated system. The uniqueness of this melioration system is the scale of drainage facilities created during East Prussia time and Soviet period. The characteristic of the current condition of melioration system facilities is given. Actual problems and potential risks in the context of climate change are highlighted. The relevance of digitalization in melioration sector of public administration and in in the context of transboundary cooperation is explained.The primary data model, the structure of cartographic layers, and the composition of attribute information are considered. The features of the initial data and the problems of their preparation are described. The technology of inputting poorly formalized data has been developed. Authors used own service programs for geometry control, topology, and automation of operations, which allows increasing the productivity and accuracy of data input in comparison with standard means of basic geographic information systems.Thematic maps, examples of which are given, are the information basis for monitoring of drained lands of the Kaliningrad region to make environmental and economic management decisions. Promising areas of application of the geodatabase are proposed: geoportal project based on server data storage with using satellite information; project for hydrological modelling of hazardous and catastrophic occurrence in various melioration subsystems.The created geodatabase allows increasing the efficiency of processing and analysis of information about melioration systems on a local and regional scale enables the geographic visualization, helps in melioration management making-decisions.
