Application of Web-GIS and Cloud Computing to Automatic Satellite Image Correction

Radiometric calibration of satellite imagery requires coupling of atmospheric and topographic parameters, which constitutes serious computational problems in particular in complex geographical terrain. Successful application of topographic normalization algorithms for calibration purposes requires integration of several types of high-resolution geographic datasets and their processing in a common context. This paper presents the application of an operational system for cloud-based radiometric and topographic calibration of satellite imagery. The system uses a Web-based Geographic Information System integrated within a High Performance Computing environment for remote processing of uploaded satellite data. The article also presents sample results produced by the system and discusses the benefits of using a cloud-based environment.
