摘要：For location based GIS(Geographic Information Systems) services, to provide spatial data and spatial data processing functions to various users including personal users and other ASPs(Application Service Providers), a standard interface is necessitated. As location based GIS services can be provided through a layered architecture, separate interfaces are needed for each layer. The focus of this paper is to define a common interface for the layer that lay on the bottom of the layered architecture and provides spatial data and spatial data processing functions for upper layer's use. The spatial data and spatial data processing function accesses supported by this interface are specifically designed for location based GIS services in the wireless internet environment. And also, for the sake of interoperability, the interface definitions of this paper are based on XML(eXtensible Markup Language) schema and compatible with corresponding OGC(OpenGIS Consortium) standard interfaces
