User interface design and development for point pattern analysis using the technique "quadrat analysis " in a GIS environment

Abstract

The description and analysis of the spatial pattern of point distributions constitutes a significant geographical problem. Spatial patterns are connected with relevant spatial procedures. These procedures can be described through the utilization of statistical tools. One of the most widespread spatial analysis techniques that are used for point pattern analysis is "Quadrat Analysis". The aim of this paper is the design and development of a user interface in a Geographical Information System, which will be able to detect the spatial patterns from point distributions, through the use of the technique "Quadrat Analysis". The user interface has been designed and developed in order to be integrated, flexible, friendly and easy to use. For this purpose, the basic principles of the theory of point pattern analysis are presented, as well as the basic principles of the development of a user interface that should characterize the user interface of all information systems.
