AccessibleMap: web-based city maps for blind and visually impaired

Today cities can be discovered easily with the help of web-based maps. They assist to discover streets, squares and districts by supporting orientation, mobility and feeling of safety. Nevertheless do online maps still belong to those elements of the web which are hardly or even not accessible for partially sighted people. Therefore the main objective of the AccessibleMap project is to develop methods to design web-based city maps in a way that they can be better used by people affected with limited sight or blindness in several application areas of daily life.

Information Fusion and Geographic Information Systems (IF&GIS' 2015)

Personal GeoServices are emerging as an interaction paradigm linking users to information rich environments like a university campus or to Big Data sources like the Internet of Things by delivering spatially intelligent web-services. OpenStreetMap (OSM) constitutes a valuable source of spatial base-data that can be extracted, integrated, and utilised with such heterogeneous data sources for free. In this paper, we present a Personal GeoServices application built on OSM spatial data and university-specific business data for staff, faculty, and students. While generic products such as Google Maps and Google Earth enable basic forms of spatial exploration, the domain of a university campus presents specific business information needs, such as “What classes are scheduled in that room over there?” and “How can I get to Prof. Murray’s office from here?” Within the framework of the StratAG project (www.StratAG.ie), an eCampus Demonstrator was developed for the National University of Ireland Maynooth (NUIM) to assist university users in A.

Information Fusion and Intelligent Geographic Information Systems (IF&IGIS'17)

The major purpose of this paper is to discuss two phenomena: (1) geographic information systems (GIS) and (2) space. The discussion is from a computer science point-of-view. As it is well known, every point in GIS can be presented in 1D, 2D, 3D or nD dimension. If we take a look on linear algebra, we can find definitions of “space” and “subspace.” Therefore, the major point of our discussion is to determine space and subspace in GIS and to introduce some measures for dynamic space borders and other properties that can be calculated by different methods. The complexity of the proposed paper arrives from an original complexity of space definition and because of the fact that it is used in abstract algebra, philosophy, and GIS paradigms together.
