Web-Based Geoinformation System for Exploring Geomagnetic Field, Its Variations and Anomalies

Abstract

In the modern World, specialists in many scientific and applied spheres consider parameters of geomagnetic field, its variations and anomalies as one of the key factors, which can influence on systems and objects of various origins. The estimation of the influence requires an effective approach to analyze the principles of distribution of geomagnetic field parameters on the Earth’s surface, its subsoil and in circumterrestrial space. The approach causes a complicated problem to be solved, which is concerned with modeling and visualization of parameters of geomagnetic field, its variations and anomalies. The most effective and obvious solution to this problem is supposed to be a geoinformation system, because of the geodata-centric character of the problem itself. In this paper the authors suggest the solution, which is based on modern geoinformation and web technologies and provides the mechanisms to calculate, analyze and visualize parameters of geomagnetic field and its variations.
