Layout of an interoperable information-analytical system for spatial and semantic search and analysis of geodata

The paper describes the principle of operation and the functionality of the layout of an interoperable information-analytical system designed to perform the tasks of spatial and semantic search and analysis of geographic data by the example of landforms and elements of a hydrographic network on the basis of the model of interoperability proposed by the authors. To search geoimage data in arrays, the authors use an approach taking into account not only text, but also visual descriptors, reflecting the substantial and visual (shape, color, and texture) features of natural geoobjects, processes, or phenomena. The authors created a fragment of a verbal-graphic thesaurus containing visual descriptors of objects of the hydrosphere and designed the layout of the search engine used to search geoobjects in a repository of geospatial information. The layout of the system was developed in Microsoft Visual Studio 2008 and operates using Microsoft SQL Server 2005.
