| Summary: | 碩士 === 朝陽科技大學 === 資訊管理系碩士班 === 91 === Standardization, interoperability and transparency are important issues in computer science. These issues seem to be, howerver, ignored in the field of geospatial information management. Many organizations are still using traditional and proprietary data formats such as ESRI shapefile and MapInfo TAB, which causes lots of troubles when geospatial data need to be shared or transfered. This problem is compounding every time a new proprietary format is introduced. It also conflicts with the goal of building re-usable systems and promoting information usage. Open GIS Consortium was formed in the 1994. It proposes the Open Geodata Interoperability Specification based on new technologies such as Distributed Computing, Pluggable Computing Model, and XML. In this research, we discuss this specification, compare it with earlier
alternatives, and finally give an implementation on cadastral data using free softwares. We hope that people begin to see the long-term benefits of adhering to open standards such as OGIS and of the softwares whose source codes can be studied and modified at will.
