Security for GIS N-tier Architecturentrol mechanism in legacy DBMS. Cryptography solutions as a topic of central importance to many aspects of network security are discussed in detail. This part of the paper describes several traditional and new symmetric, fast and nonlinear encryption algorithms’ implementation with fixed and flexible key sizes.

Representing Topological Relationships between Complex Regions by F-Histogramsrelationships between two regions in terms of the thirteen Allen relations. An index to measure the complexity of the relationships in an arbitrary direction is developed, and experiments are performed on real data.

An Efficient Natural Neighbour Interpolation Algorithm for Geoscientific Modellingand three dimensions, but it can be generalized to higher dimensions. Our algorithm, which uses the concept of flipping in a triangulation, has the same time complexity as the insertion of a single point in a Voronoi diagram or a Delaunay triangulation.

Evaluating Methods for Interpolating Continuous Surfaces from Irregular Data: a Case Studyrveyed values for the real surface. The differences between interpolators are shown with a variety of measures, including visual inspection, global statistics and spatial variation, and the utility of cubic interpolators for representing curved areas of surfaces demonstrated.

Finding REMO — Detecting Relative Motion Patterns in Geospatial Lifelinesspatial lifeline data. Our approach considers the object’s motion properties in an analytical space as well as spatial constraints of the object’s lifelines in geographic space. We discuss the geometric properties of the formalised patterns with respect to their efficient computation.

Shiv Narayan,J. Sreeja,Raveendranath U. Nair This paper discusses an architecture developed to enable a user to query spatial data from a collection of distributed heterogeneous data sources. This has been implemented using GML to facilitate data integration. The system is currently being used to study the handling of positional uncertainty in spatial data in such a system.
