Abstract

Abstract. We propose to advance the scientific understanding and applications of geospatial data by coupling Sensor Web and Geoprocessing Services in Virtual Globes for higher-education teaching and research. The vision is the concept of "What You See is What You Get" geoprocessing, shortly known as WYSIWYG geoprocessing. Virtual Globes offer tremendous opportunities, such as providing a learning tool to help educational users and researchers digest global-scale geospatial information about the world, and acting as WYSIWYG platforms, where domain experts can see what their fingertips act in an interactive three-dimensional virtual environment. In the meantime, Sensor Web and Web Service technologies make a large amount of Earth observing sensors and geoprocessing functionalities easily accessible to educational users and researchers like their local resources. Coupling Sensor Web and geoprocessing Services in Virtual Globes will bring a virtual learning and research environment to the desktops of students and professors, empowering them with WYSIWYG geoprocessing capabilities. The implementation combines the visualization and communication power of Virtual Globes with the on-demand data collection and analysis functionalities of Sensor Web and geoprocessing services, to help students and researchers investigate various scientific problems in an environment with natural and intuitive user experiences. The work will contribute to the scientific and educational activities of geoinformatic communities in that they will have a platform that are easily accessible and help themselves perceive world space and perform live geoscientific processes.

Highlights

  • With the advancement of Earth observing and sensing technologies, the geospatial data is increasingly rich and accessible in real-time or near-real-time ways

  • In order to help geospatial users analysis these data in an environment with natural and intuitive user experiences, this work proposes the concept of “What You See is What You Get” geoprocessing, shortly known as WYSIWYG geoprocessing, by coupling Sensor Web and geoprocessing Services in Virtual Globes

  • The wide popularity of Virtual Globe software such as Google Earth, Microsoft Virtual Earth, and NASA World Wind offers tremendous opportunities, such as providing a learning tool to help educational users digest global-scale geospatial information about the world, and acting as WYSIWYG platforms, where domain experts can see what their fingertips act in an interactive three-dimensional (3D) virtual environment

Summary

INTRODUCTION

With the advancement of Earth observing and sensing technologies, the geospatial data is increasingly rich and accessible in real-time or near-real-time ways Often, these data have to be transformed into user-specific information and knowledge through geoprocessing methods. In order to help geospatial users analysis these data in an environment with natural and intuitive user experiences, this work proposes the concept of “What You See is What You Get” geoprocessing, shortly known as WYSIWYG geoprocessing, by coupling Sensor Web and geoprocessing Services in Virtual Globes. Coupling Sensor Web and geoprocessing Services in Virtual Globes will bring a virtual learning and research environment to the desktops of students and professors, empowering them with WYSIWYG geoprocessing capabilities. The implementation combines the visualization and communication power of Virtual Globes with the on-demand data collection and analysis functionalities of Sensor Web and geoprocessing services, to help students and researchers investigate various scientific problems in a natural and intuitive environment.
