Introduction
� Space & time are often the only obvious connection(s) among observations
� Spatial information
� is decisive to understand and respond to the world and its events
� is vital for many businesses and societies
� is essential for managing environment, resources
and risk assessment
� Spatial data infrastructures
� help organizing spatial data & services
� Geoportals
� are linking spatial data providers
� with information users and
� and share spatial information in a virtual project library

Standardized Geographic Information
Infrastructures
� Geodata infrastructure = Spatial data Infrastructure
Geographic information infrastructures = geodata & user oriented
distributed geographic information services
� structured organization of geodata and geographic information
services
� based on a common technical infrastructure (IT-technologies)
bringing in interoperability
� usage of internationally accepted standards for technological
interoperability based on Open Geospatial Consortium (OGC) and ISO
standards as lingua franka to guarantee interoperability
� integration of legal requirements (cadastral laws, INSPIRE directive)
and global initiatives (GEOSS) � definition of common semantics
harmonized organizational concepts

Standardized Geographic Information
Infrastructures - Why
� For effective & efficient organization of geoinformation
� improve data access
� promote data reuse
� make information readily available
� ensure that investments for data collection and management result in
a growing pool of information
� ways of leveraging spatial information
� Change from monolithic IT-systems towards distributed architecture
� are becoming independent of computing platforms
� geo-portals serve as gateways to spatial-information

Standardized Geographic Information
Infrastructures - Answers
� The term “infrastructure” suggests and supports the “concept of a
reliable, supporting environment”, analogous to a road or
telecommunication network – that’s what first responders need!
� Spatial data infrastructures are needed to enable GIS proliferation
throughout organizations, enterprises, countries even globally to
� disseminating information and knowledge in a better, faster and up-to-
date way
� The underlying organizational and technical concepts have to be evaluated
and adjusted
� New technological opportunities, standardization and semantic information
harmonization approaches (e.g. INSPIRE data Specifications) and global
initiatives like GEOSS (Global Earth Observation Systems of Systems

Standardized Geographic Information
Infrastructures – the road ahead
� Enhancing GI infrastructures
� Perform distributed analysis of geographic information using cloud
computing architectures leveraging standardized SOA technologies
� Upcoming need to (real)-time-enable geo-enabled sensor measure
layers
� historical catalogs � real-time geo-infrastructure
e.g. information exchange and indeed its integration across
heterogeneous systems of rescue and relief organizations

Sensor Networks
status quo
� Heterogeneous data sources, various data formats
� Service-oriented access to data not fully developed (still)
� Lack of up-to-date in-situ sensor measurements
� How about registration and finding of resources and services
� Developments for a particular purpose � no cross integration

� Transition: monolithic and mostly post-processing system � service-
oriented near real-time analysis architectures
� Context-aware information in place of ‚raw-data‘
� Distributed geo-processing routines to enhance performance for time-
critical spatial decision support
� Quality assurance by integrating spatially aware Complex Event
Processing � neighborhood relationships of sensors

Conclusion
� Information integration in geo- information infrastructures is a key
requirement for
• exchanging geographic data internally/externally
• managing and optimizing organizational workflows, production processes
• an essential element for safety and security support
� Goal
• structure and provide information in a modern SDI
• provide data and applications via a geoportal
• Ensure information quality regarding accuracy, completeness and up-to-dateness
• design contextual geo applications based on the need of specific user groups
� Outlook
• Integrating eventing and alerting mechanisms (SAS / SES)
• Distributed processing / cloud computing fractional interpolation
