摘要
In this paper,we present GSio,a software system for serving geospatial raster or gridded Big Earth Data at scale.GSio allows different scientific communities to consume geospatial analysis ready data.It provides a generic interface to the data,which removes the need to interact with individual files,and can interoperate with existing geospatial collections hosted on data centres and public clouds.A distributed compute model is used to read and transform the data in parallel using a cluster of compute nodes for delivering data as a service to users.Several use cases are presented demonstrating different scenarios where this service has been used.
