Principles of Geographical Information Systems

Geographical Domain and Geographical Information Systems

In the eld of geography, we have beenexamining the contribution of the morpho-genetic rep-resentation to the comprehension of the cycle: reality,representation, model, reality. A distinction is madebetween map and geomap based on the notion of locus-object. 1. Foundations and limits of cartographic rep-

On the reduction of the ordinary kriging smoothing effect

A simple but novel and applicable approach is proposed to solve the problem of smoothing effect of ordinary kriging estimate which is widely used in mining and earth sciences. It is based on transformation equation in which Z scores are derived from ordinary kriging estimates and then rescaled by the standard deviation of sample data and the sample mean is added to the result. It bears the grea...

Evolution of Geographical Information Systems

SUMMARY Geoinformatics is described as a scientific and technical complex integrating the branch of scientific knowledge, the appropriate technology and the applied, or productive, activities concerned with the development and implementation of geographical information systems. Four stages of geoinformatics evolution are discussed, and its prospects are outlined in brief. 1. Introduction Geoinf...

Geographical Information Systems An Overview

Although many GIS have been successfully implemented, it has become quite clear that two-dimensional maps with most complex contours and color schema cannot precisely present multidimensional and dynamic spatial phenomena. Most GISs in use today have not been designed to support multimedia data and therefore have very limited capability due to the large data volumes, very rich semantics and ver...
