Abstract: To solve the problem about function configuration, scalability and multi-tenancy efficiency based on the geographic information system (GIS) fourth level model of "Software as a Service" architecture, the model architecture for GIS service engine of configurable function is presented. And the kernel technologies including work flow, function warehouse, configuration, right management for GIS service engine of function configuration are introduced. Then remote image application system is constructed based on the technology of GIS service engine of function configuration, and it provides technical support for the new application model of software as a service.
