本文介绍了最新的设计和实现的低成本创新的在线安全的数据库服务，也被称为Web处理服务，它承担全自动的实时，在线，按需精确的地理参考的空间和属性数据的提取，传输和融合。该服务随后为联合王国学术界的最终用户立即生成准现实地理空间人口模型。本文介绍了实现的系统架构，设计和运行机制，流程和工作流程，自动精确的在线服务调用，从在线数据密集型数字存储库和服务中提取地理空间数据和属性数据，以及保证完整性和质量的自动数据融合。作为一个组成部分，这些包括后续的自动高性能搜索引擎，用于生成地理空间模型和在互联网上提供服务。它解释了一组专门设计和编码的地理处理器和相关的地理参考编码系统是如何产生的，以执行连贯的连锁行动，在一个新的工作流程，统一行动，以满足最终用户的需求。据信，此类自动地理数据处理服务可用于按需处理数量不断增加的环境数据。
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.
