An Approach to Service and Cloud Computing Oriented Web GIS Application

Abstract

The service and cloud computing oriented architecture is a very promising architecture for practical implementation of the next generation geographical information systems. This paper investigated the service and cloud computing oriented architecture for constructing a distributed and web service enabled geographical information platform. The spatial cloud computing applies geographical information systems to the cloud computing paradigm. It provides dynamically scalable geographic information technology, spatial data, and spatial applications as a web service. GIS web services were designed to provide the hosted spatial data and GIS functionality to integrate the customized GIS applications to perform basic geo-processing tasks, such as address matching, map image display, and routing, without maintaining GIS tools or the associated geographical data. The system architecture, functions, system integrations, and some key technical problems are investigated. It has an important application prospect in the GIS tools development and application.
