Abstract

Virtual Globes such as Google Earth TM, revolutionize the way scientists conduct their research and the way the general public use geospatial – related data and information. Improvement in the processing power and storage capacities of computers, along with the increased Internet accessibility and connectivity, has supported the usage of Virtual Globes technologies. Even more, software releases of freely downloadable Virtual Globes, such as Google Earth and NASA World Wind, has sparked an enormous public interest and increased people’s awareness of spatial sciences.In this study, the Virtual Globes (VG) revolution is discussed and a client - server Graphical User Interface (GUI) application is presented. The developed application enables Google Earth TM Application Program Interface and activates spatial analysis, through enhanced JavaScripts and Visual Basic script codes. The main scope was to present the methodology followed during geological modeling along with the application capabilities when handling with data derived from digitized geological maps and field measurements.

Highlights

  • In every geosciences model that simulates a natural system, interactive data manipulation and visualization, are the most essential tools [1]

  • The main scope was to present the methodology followed during geological modeling along with the application capabilities when handling with data derived from digitized geological maps and field measurements

  • The main scope of this study is to develop a form of client-server Graphical User Interface (GUI) application, transforming the static Geographic Information System (GIS)-based applications into a more dynamic tool for data input, manipulation and visualization

Summary

Introduction

In every geosciences model that simulates a natural system, interactive data manipulation and visualization, are the most essential tools [1] The projection of these procedures and their analytical results, are usually presented by the form of digital or analogous thematic maps [2]. By the end of the millennium, it was well established the idea of a computer application, allowing users to browser and search geographically indexed information, projected on a cartographic representation of the Earth in various scales and projections [5] The materialization of this idea was based on technological advantages, such as orbiting satellites with spatial resolution of a few meters, improvements in hardware and software and the growth of broadband internet, where users have World Wide Web (WWW) access without slow speed and telephone line disruption [6]. The main scope of this study was to provide a methodology through a well designed Graphical User Interface application that enables the Virtual Globe technology providing a helpful tool for handling geological data in a more sophisticated manner
