摘 要：正By discussing Grid GIS,UbiGIS and OpenGIS, and analyzing the challenges that current geo- computing facing,the paper concludes that geo- computing should be more suitable for common people to understand and *** and supported by on demand computing,the paper presents a geo-computing strategy termed on-demand geo-computing （ODGC）.Comparing with Grid GIS,UbiGIS and OpenGIS,the paper suggests that ODGC focus on the strategy that provides users with geo-computing capabilities on their *** paper breaks the on-demand feature into suitability, temporal-validity and easy-to-use features,and develops a conceptual model termed geo-VO to achieve these ***-VO is the fusion of virtual organization,information supply chain and geospatial information value-add ***-VO functions as both geo-computing domain reference model and coordinative computing model of distributed geo-computing ***-task-VO is another conceptual model that describes how ODGC *** paper discusses ODGC philosophy by geo-VO and geo-task-VO and the ingredients that enable the agileness,easy-to-use and on-demand *** illustrate and provide an intuitive picture of ODGC,an example termed geographical cartography service is developed to explain how an ODGC application and service is developed and *** the end,the paper concludes ODGC and suggests the future studies.
