Cloud computing platform for GIS image processing in U-city

Ubiquitous city (U-city) is a city with ubiquitous information technology that enables citizens to access the converged information anywhere and anytime. A lot of compute power are required in U-city, because large amount of data should be processed in real-time. Cloud computing enables users to use the abstracted and virtualized computing resources and to process huge amount of information without having their own computing power. This paper presents a GIS image processing platform that uses cloud computing. It finds and selects optimal computing resources for applications and run virtual machines to execute the applications. In this paper, we explain the parallel air pollution map generation as a use case for the suggested platform and show how efficiently it processes the massive data.
