Seite 5 Global Responsibility We may not be affected directly by climate change with life destroying droughts, floods, storms and other disaster... but we - and life of future generations - will not escape uneffected !!! We have a global responsibility. Developing our understanding of these issues is extremely important. All sectors need to play an equitable part. GIS-technologies will have a key role to play in both monitoring impacts on our enviroment and in identifying solutions by Mr. Dan Wallace, Minister of State, Ireland, Demand for geodata - 5

Seite 35 Interoperability Topic: for realization of a SDI and geodata market with reasonable and economic use of geodata an interoperable geoprocessing is required Open GIS Consortium serves the inter......rests of all sectors of the industry to realize a component - based infrastructure for geodata and develop such a SDI and geodata market. - Interoperability - 35

Seite 36 Interoperability Interoperable Geoprocessing  geodata integration  maximized benefit from legacy geodata  geographic feature semantics translation  network-based geoprocessing  better use of databases  componentware  geoprocessing integrated into workflow  new non-expert users and market growth - Interoperability - Folder:OpenGIS TM, Consortium, Inc

Seite 37 Interoperability Open GIS is  transparent access to heterogeneous geodata and geoprocessing resources in a network environment Open GIS needs  a comprehensive open interface specification which enables developers to write software that provides these capabilities Open GIS enables  to build task-specific geoprocessing functions into any information system  to bring new capabilities to a wide variety of user environment. - Interoperability - 37

Seite 38 Transparency on Geodata Market Topic: transparency is required to stimulate geodata market  is given by a ´meta information system‘ and a ´meta meta information system´ that inform about data availability and address and conditions for access  is given by certificates for homogeneous data description and conformity with data quality - Transparency geodata market - 38

Seite 39 Transparency on Geodata Market Meta information system for geodata  is in preparation by DDGI  based on a consistent and harmonized description model  will be implemented in 2001 at Geoforschungszentrum Potsdam  enables geodata owner to present products - Transparency geodata market - 39
