Geographic environment is a combination of natural and cultural environments under which humans survive. Virtual Geographic Environment (VGE) is a new multi-disciplinary initiative that links geosciences, geographic information sciences and information technologies. A VGE is a virtual representation of the natural world that enables a person to explore and interact with vast amounts of natural ...

Road networks are important for modelling the urban geographic environment. It is necessary to determine the spatial relationships of road intersections when using maps to help researchers conduct virtual urban geographic experiments (because a road intersection might occur as a connected cross or as an unconnected bridge overpass). Based on the concept of using different map layers to organize...

This paper explores the provision of adaptive hints based on attainment levels in the context of supporting the development of young adults’ ICT information processing skills. We describe the design of the LIBE VLE, particularly its personalisation and adaptation features, and a User Study undertaken with young adults at a vocational education centre. Using data collected through the LIBE VLE, ...

this paper argues that the geovisualization research should go beyond the development of geovisual analytic toolbox, and pay attention to supporting human work in broad activity scale. Future generations of virtual geographic environments are expected to be capable of monitoring and recognizing context changes, reasoning about implications, and adjusting its service behavior accordingly. This w...

Geosimulation aims at modeling systems at the scale of individuals and entity-level units of the built environment and provides a new way to simulate how geographic spaces can be used by their future users, particularly in urban environments. In the MAGS Project we are developing a generic software platform for the creation of Multi-Agent Geo-Simulations involving several thousand agents intera...

Virtual geographic environments (VGE) are environments pertaining to the relationship between post-humans and 3-D virtual worlds. Post-humans are defined as a combination of humans in the real world with 3-D avatars in 3-D virtual worlds. Five types of space, namely Internet space, data space, 3-D graphical space, personal perceptual and cognitive space, and social space are used to explore the...

In this paper, we address two challenging issues underlying spatial cognitive simulation using software agents immersed in Virtual Geographic Environments (VGE). First, the way to describe virtual VGE models using accurate spatial decomposition approaches structured using graph theory techniques. Second, the use of graph abstraction techniques to realistically support advanced navigation and pa...

Virtual geographic environments (VGE) are environments pertaining to the relationship between post-humans and 3-D virtual worlds. Post-humans are defined as a combination of humans in the real world with 3-D avatars in 3-D virtual worlds. VGE can be a platform for the public participation in spatial data analyses, in model computation and simulation, and in environmental planning and decision m...

LiDAR technology can provide very detailed and highly accurate geospatial information on an urban scene for the creation of Virtual Geographic Environments (VGEs) for different applications. However, automatic 3D modeling and feature recognition from LiDAR point clouds are very complex tasks. This becomes even more complex when the data is incomplete (occlusion problem) or uncertain. In this pa...
