Web-based processing of remote sensing data in a workflows environment

Since its inception, Earth observation from space has been hampered by the difficulty of managing and processing the enormous volumes of data that satellite sensors are capable of generating. Modern sensors are able to produce more channels of spectral data more frequently at greater spatial resolution than ever before, and the range of potential geophysical products is continually increasing. Generation of products, access to, analysis and visualisation of these large data sets is often perceived as highly technical and an often daunting set of procedures. This paper introduces a project aimed at providing to non-technical users access to a suite of tools via a web-based graphical user interface to a Workflows system (RS-YABI), linked to a high performance computing system and a national- scale remote sensing data archive.
