We present results on the design of a visual interaction environment for GISs based on focus+context visualisation and details-on-demand data presentation. We consider databases consisting of spatially related collections of regions with features, hierarchically organised as a nested partition. Interaction processes generate views on the database, displayed by maps preserving topological proper...

This paper discusses an architectural model that is used in implementation of Ginis framework for realization of open and scalable Web-based geographic information systems (WebGIS). WebGIS system is considered as a whole that consists of a WebGIS portal and many Web-enabled GISs. For developing of all application components of an overall WebGIS, we introduced and developed unified model of geoi...

The SketchMapia aims at relaxing technical constraints on Geographic Information Systems (GISs) by developing a framework taking freehand drawn sketch maps as input. This paper describes the framework that is designed to provide non-expert users of geospatial information with alternative methods for contributing data to and querying geographic information systems. The architecture of the framew...

Much work has been done in the area of qualitative spatial reasoning over the past years, with application in various domains. However, existing models only capture particular aspects of the spatial relations between objects and therefore are unable to represent these relations accurately. In this paper, we draw together two existing approaches to provide a calculus taking into account topology...

Increasing number of geodata producers and users in local community environment have expressed the need for the integration of geodata from distributed information sources and for interoperable GISs. The systems that own this data must be capable of interoperation with systems around them, in order to make access to this data to become feasible. The system also must deal with issues unique to g...
