Abstract
This paper presents the latest design and realisation of a low-cost innovative online secure geoprocessing service, also known as web processing service, which undertakes fully automated real-time, online, on-demand precise geo-referenced spatial and attribute data extraction, transfer and fusion. The service carries out subsequently immediate generation of quasi-realistic geospatial population models for end users in the United Kingdom’s academic community. The paper presents realised system architecture, design and operational mechanisms, processes and workflow for automatic precise online service invocation, extraction of geospatial data and attributes data from online data-intensive digital repositories and services and automatic data fusion of assured integrity and quality. As an integral part, these include following-on automatic high performance geoprocessing for generating geospatial models and service delivery over the Internet. It explains how a set of specially designed and coded geoprocessors and associated geo-referencing coding system are produced to perform coherently chained actions in a novel workflow to act in unison to meet the end users demand. It is believed that such types of automated geodata processing services can be used for on-demand processing of an ever increasing amount of environmental data.
