9. Nov. 2001 Copyright Galdos Systems Inc. November 2001 GML - Builds on W3C Standards

10. Nov. 2001 Copyright Galdos Systems Inc. November 2001 GML: What is it ? OGC Endorsed “Adopted Specification” (GML 2.0 passed March 2001) for encoding spatial information. A set of XML technologies for handling spatial data on the Internet. Emerging international standard for spatial data— endorsed by 200 + companies and agencies around the world. Will converge with G-XML (Japan) – additional 600 companies. Target is GML 3.0 by December 2001

11. Nov. 2001 Copyright Galdos Systems Inc. November 2001 Geography Markup Language XML encoding of geography (Web GIS) A schema language (based on XML Schema) for creating geographic application schemas or vocabularies. Basis for creating types (ADT) for input/output (request/response) types for web-based services.. Enables complex features & feature associations

12. Nov. 2001 Copyright Galdos Systems Inc. November 2001 GML - What is it? GML => Geo-spatial schema language GML => Geo-spatial world wide web Shared vocabularies and schemas Shared data – create once – use anywhere !

19. Nov. 2001 Copyright Galdos Systems Inc. November 2001 What is a Link ? Pointer ? A kind of static or dynamic association between two resources. Links can be within the same “file” Links can be thought of as semantic associations Resource A Resource B link

20. Nov. 2001 Copyright Galdos Systems Inc. November 2001 Geo-spatial View of Links/Pointers Extend a feature by adding new attributes – remote geometry. Express relationships between geo-spatial features and non-spatial properties (remote properties) Express relationships between geo-spatial features. Associate datasets that cover and refine a given area.

24. Nov. 2001 Copyright Galdos Systems Inc. November 2001 Implications of GML Makes it possible to build a spatial infrastructure – reduces the incremental cost of building telecom specific data sets. Makes it easier to integrate spatial information with non-spatial information – “e-mail me a map I can interact with”! => Better utilization of spatial information. Leads to geographic standards for telecommunications – standard shareable vocabularies – lowers cost of data sharing and increases interoperability. Provides a flexible, open, standard transport for geographic information for location-based applications. Allows vendors to focus on content!
