The cloud computing for a dynamic agro-geoinformation processing

How to evaluate all sorts of heterogeneously online geospatial web resources (e.g., OGC web services, online geospatial data) as a top-to end operational unit is a main geospatial research topic in this period. The cloud computing technology is the infrastructure to use internet and central remote servers to organize all kind of computational Web resources as a service. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. This paper presents the prospect of cloud computing technology´s application in the agriculture geospatial information research field. In this paper, a Web Processing services (WPS) based geospatial processing framework is deployed in the Amazon cloud computing platform, then the cloud WPS environment is applied to calculate the Normalized Difference Vegetation Index (NDVI) value, which can be used to monitoring the crop condition.
