This work investigates the practical issue of mapping existing GIS to the OpenGIS standards. We describe the data models used in three systems (MGE, ARC/INFO and SPRING) and analys...
Abstract. In order to allow blind and deafblind people to use and explore electronically available maps, we have developed a system that displays maps in a tactile way using a stan...
We address the problem of conformally mapping the unit disk to polygons with elongations. The elongations cause the derivative of the conformal map to be exponentially large in so...
This paper proposes a real-time hybrid solution between standard shadow mapping and any of the current perspective shadow mapping based methods. Existing methods are known to have...
As the XML has become a standard for data representation, it is inevitable to propose and implement techniques for efficient managing of XML data. A natural alternative is to expl...
