Ppt Understanding Geospatial Data Exchange With Gml Gis Standards A profile offers a controlled subset of gml that makes interoperability and wide implementation more achievable. esri has taken the initiative by defining a gml profile and implementing this profile in a free software extension. A profile of gml can be defined to enhance interoperability and to curtail ambiguity by allowing only the use of a specific subset of gml in the definition of a gml application schema.
Ppt Understanding Geospatial Data Exchange With Gml Gis Standards This common data m odel, which is a gml profile, is the starting point for other data model creators. based on this common data model, more specific data models can be created. In practice profiling such standards is useful to overcome such issues to create more useful forms of standardised data for specific applications. however defining custom profiles typically requires a great deal of technical expertise in the underlying expression language of the standard. In this paper, three methods of spatial data sharing and interoperability are discussed, especially data sharing based on web spatial data service and geography markup language (gml). Interoperability is the ability of a system, or components of a system, to provide information portability and inter application cooperative process control (bordie, 1992). two kinds of interoperability can be distinguished. for a program, data interoperability means the ability to utilize a range of data formats.

But gml 3 defines several complex entities such as topologies, dynamic features, and nested features, and these entities have many optional aspects. this impacts the way gml consumers would process a data exchange, as well as the potential for achieving interoperability. Based on web service and ows model of ogc, this paper built application integration layer, web application manager layer, service registry layer, and gml spatial data storage layer for gml spatial interoperability framework. The significance of gml lies in its ability to promote data interoperability, which is critical in geospatial analysis. with gml, users can easily combine and analyze data from different sources, gaining a more comprehensive understanding of complex spatial phenomena. A profile of gml can be defined to enhance interoperability and to curtail ambiguity by allowing only the use of a specific subset of gml in the definition of a gml application schema.
