The article examines some challenges in the development and processing of data containing complex structured geospatial information that are associated with large amounts of data, their dimensionality and an increased number of spatial/logical and topological relations between data elements, as well as data heterogeneity. The most popular tools for processing such information are described. We discuss the organization of storage, processing and analysis of spatially distributed topology data in the environment of the GIS Terra. The main features (models, structures and data formats) of the developed topological structured object model are examined. We also consider options for organizing the management system for databases of spatially distributed data for different hardware and software platforms (Windows and Android) in the local and client-server variants. Data migration schemes are presented for the integrated use of different hardware and software platforms. Some recommendations are given concerning the development of new applications for the analysis and processing of spatially distributed data using the developed data storage and processing tools.
