Demand for geodata
• all spatial planning and decision making needs–a description of geotopography of the earth´s surface–a connection to the earth´s surface
• the description of geotopography consists of–pictorial and objectoriented planimetric information–height information–as geobasis

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

Problems
• old concepts for cadastre (ALB/ALK) and topographic (ATKIS) information systems
• no systematic object-related view in ALB/ALK
• strong differences between ALB/ALK and ATKIS
• no consistant data modelling between cadastre and topography
• difficulties in realisation of cartographic aspects
• no “standard” notation of the data models
• no concept to integrate metadata (data quality)

Activities
situation is not really known
to realize geodata market investigations have to be done
to capture and analyze the situation

component - based infrastructure for geodata and
develop such a SDI and geodata market.

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.

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
