An Interoperability Gis Model Based on the Spatial Information Infrastructure
نویسندگان
چکیده
Increasing application of Geospatial information requires integration , fusion and interoperability of current monolithic GIS, especially more complex and multidisciplinary involved application. Interoperability is base for information integration and fusion. we give five-level GIS interoperability model(InteroModel5). The spatial information infrastructure(SII) provides a sharing spatial information framework , architecture and an interoperability platform for geographical information system. This paper studies architecture of spatial information infrastructure, and gives the relationship between GIS interoperability model and spatial information infrastructure architecture. We consider GIS interoperability model provide a theory base for SII, and SII provide an implementation platform for GIS interoperability model .

Role of a Clearing House Server Infrastructure for GIS Interoperability
This paper discusses the development GIS interoperability infrastructure which allows end user to search, locate and finally work at the end with all available geo-spatial data without bothered too much by format differences. Rapid development of internet technology allows more spatial and tabular data available and accessible publicly. However, it has been identified those data can not be util...
متن کاملISIS: A Semantic Mediation Model and an Agent Based Architecture for GIS Interoperability
The diversity of spatial information systems promotes the need to integrate heterogeneous spatial or geographic information systems (GIS) in a cooperative environment. This paper describes the research project ISIS (Interoperable Spatial Information System) which is a semantic mediation approach to support GIS interoperability. Its key characteristic is a dynamic resolution of semantic conflict...
