Geographical Institute at the Humboldt University

Profile• One of the oldest Geography

departments in Germany (1810)• Since 2003 situated in the Technology Park

Adlershof

• Institute with departments of physical and human geography, didactics and...

• Geomatics department:head of department (Prof. Patrick Hostert) + Geovisualisation and Cartography (Prof. Dransch) + Applied Geoinformatics (Prof. Margraf)+ Juniorprofessor for Geoinformatics (~ by the end of 2007)

Research at the Geomatics Department

• Land-use/land-cover change and metropolitan areas• Spatial modeling • Geodata-management and geo-visualisation (Geodata

infrastructure)

German Aerospace Centre (Deutsches Zentrum für Luft- und

Raumfahrt – DLR)

Part.: research on traffic, geoscientificremote-sensing, applied remote-sensing

Institutes of the Humboldt University of Berlin

Part.: Informatics, Chemistry, Psychology and centre of multimedia

learning

• Cooperation with research institutions on Campus Adlershof

5


Research: remote-sensing

• Focus: Remote Sensing for mapping land-use and land-cover (changes)

• regional focal points are metropolitan areas worldwide (esp. Berlin), Eastern Europe and the European Mediterranean

• Variety of data (high resolution satellite data, hyperspectral data…)

• Development of methods and approaches (knowledge-and rule-based interpretation, Support Vector Machines, Spectroscopy, radiative transfer model…)

• Applied research: Mapping Sealing in Berlin…

Mapping sealing in Berlin

Data: SPOT 5, vector data (ISU, ALK…)

Objective: development of a hybrid approach, multispectral classification and rule-based integration of additional geodata to map sealing

Geodata management

• Remote Sensing = one important source of information forgeographical research questions

• Integration with additional data

• Semantic/Syntactic interoperability within Geoinformatics

13


Modeling urban development

• Modeling post-socialistic urban development

• Objectives:

=> Qualification and validation of existing models

=> Integration of socio-economic and physical data

=> Management of unsure and imprecise data

• Comparison between Berlin and Warsaw (and Moscow?)

• Model: UrbanSIM

Geodata Infrastructure

• Geodata Infrastructure of the Geographical Institute

• The aim: Improving the access and availability of datawithin the Geographical Institute

• heterogeneous data on distributed computers, data bases

• often project-based data

• data of interest for all, such as ATKIS, CORINE or the data of the Senate Department

• Software: Server GIS (ArcIMS 9.0 SP3, ArcSDE 9.0 SP3)

=> possible clients: ArcMap since 8.3, ArcCatalog since 8.3, ArcIMS since 9.0...

=> Integration of external Web Services (e.g.Senate Department)? ESRI Interoperability extension…

Relevance of OGC for our research

• Heterogeneous data=> Geographic objects, coordinate transformation service...

• Distributed systems, services=> Web Services Specifications, GML...

• Concepts=> OGC adds a conceptual approach to the dominating

pragmatic and applied one

17


Teaching

• about 1500 students at the Geography Institute

• Geomatics for Bachelor, Master, Combined Master, (Diploma, Magister) in Geography

• Moduls of Geomatics also for students of Informatics and other disciplines

• Different types of teaching: Lectures, seminars, labs, project work, field work, excursions…

18

Discussion and Outlook

• Teaching:– One focus (should be) on OGC, because of increasing

importance for future working fields of graduates– knowledge to critically assess the applicability rather

than being able to implement a web-service– Geoinformatics in Geography: an integration of different

sciences (data, models, scales…)

• Research:– New conceptual approaches for distributed architectures– Improved/increasing integration of space into workflows

(GIS => Services)

• Communication: – Between companies, research institutions,

administrations… on testbeds, examples, pros and cons
