Abstract

This paper introduces the design and development of a client-side Graphical User Interface (GUI) for the NASA Spatial Web Portal. A spatial web portal is an entry point to spatial data and services within spatial platforms. The usability and efficiency of the entry point will decide the success of the entire system. This paper describes visualization and GUI designs and implementation for improving client performance. Abundant information about web service is tightly grouped into different floating windows for better information display. Asynchronous JavaScript and XML (AJAX) technology is implemented to enhance visualization performance. The mirror world tools such as Google Maps, Bing Maps, and NASA World Wind provide new mechanism for spatial data discovery and visualization. We test how the methods utilized along with Bing Maps improve the performance of the NASA Spatial Web Portal.
