Importing Abstract Spatial Data into the SAND Database System

Abstract

The World Wide Web has opened ways to operate large applications by users with simple client platforms located half way around the world by connecting servers around the world together. We present a system that makes a centrally stored spatial database available to off-site users. Regardless of the specific platform available to a user, all they need to do is simply establish a link between their client and the server. Unlike well-known web-based services such as MapQuest [2] that rely on computational power of the server, our system distributes the workload among the client and the server in such a manner that the user will observe the system as being interactive, with minimal delay between the user action and appropriate response for most types of operations. The SAND Internet Browser, the client part of our solution1, provides a graphical user interface for viewing and querying data stored on the central server. One of our design goals was to minimize specific hardware and software requirements for the client component. Our solution was to implement the SAND Internet Browser in Java, this provides maximum portability across multiple hardware platforms while not requiring anything beyond a common networked computer, i.e., an Internet-connected computer with a Java-enabled web browser. The SAND Internet Browser is continuously being improved and new functionality has been added since its earlier presentations such as [3, 4, 6, 7]. This paper accompanies a demo which introduces some of the features that have been recently added or are currently being researched and will be available in the near future.
