Contribution to the Implementation of Portable Components for Geographic Information Systems.
A Concept for Dynamical and Event-driven Visualization and Preparation of Geoscientific Data.
The object of the analyses is to create a data design that allows to open up multifarious uses by a new concept going along with the extension of the functional range. These conceptional extensions are based on the increase of informational extent of various geoscientific and especially of spatial data. Special bias concentrates onto portable event-driven and dynamic visualization and its applicability for purposes on local host systems and on networks like the Internet.
This work introduces a new and complete concept based on which techniques can be developed for solving numerous problems with dynamic cartography and multimedial presentation regarding geosciences and as an aid for interpretation and advanced mediation of measured data and results.
Closely tied with the concept established here the following terms have been introduced with this work and have been thoroughly used with source-code-based data: object graphics, event-oriented data (event data) and event-active objects.
Experiences are shown resulting from planning, development and testing of a prototype being discussed using a number of problem centered case studies that have been developed over a couple of years to proof the concept presented here.
Based on the concept put into practice the prototype offers a very high flexibility especially regarding to the application of events for using new facilities for dynamic visualization.
This prototype and the data generated along with its development are provided on the Internet.
All of the developments and tests were performed using freely available and open operating systems utilizing free and open development tools and are on principle available for any modern hardware platform.
An outlook shows numerous future developments and concrete potentialities for using techniques and applications based on this concept.
