Hangar

A New Algorithm for 3D Isovists,at limit the vision field. In this paper a new algorithm is presented for isovist calculation that can detect all objects, which block the sight in a 2D and 3D environment. Then, a demonstration with GIS data is given and some visibility indices are also presented.

The Case for 3D Visualization in DEM Assessment,f the system that allow the user to view a portion of the surface while keeping in the context of the overall area. In addition, the system displays visualizations for several quantitative uncertainty statistics. A detailed case study shows the efficacy of the system, especially the usefulness of viewing in three dimensions.

Migratory

A Hybrid Shortest Path Algorithm for Intra-Regional Queries on Hierarchical Networks,omputing the whole shortest path. At the lowest level, the hybrid algorithm requires . time and space assuming a uniform distribution of vertices. For higher levels, the path view approach takes . time and requires . space.

Automatic Map Retrieval and Map Interpretation in the Internet,ods are needed to search automatically for maps in the Internet and to make the implicit information of maps explicit so that machines can process it. In this paper we discuss how maps can be found automatically in the Internet and moreover, how the content of maps can be interpreted automatically.

Our suggested adjustment algorithm uses Minkowski sums of the involved polygons to achieve a linear number of (in)equations per relation.

Topological and Geometric Data Handling for Time-Dependent Geo-Objects Realized in DB4GeO,oduced at the beginning of the paper. Finally, an outlook is given on future geo-database work dealing with extensions of DB4GeO and the handling of geo-objects in the context of cooperative 4D metro tracks planning
