Institute of Geography GIScience - Activities Geomatics Department Humboldt University Berlin Tobia Lakes Patrick Hostert GIScience Meeting, 2nd February 2007
Content Geomatics Department at the Humboldt University Introduction Research Teaching Discussion and Outlook 2
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) 3
Research at the Geomatics Department Land-use/land-cover change and metropolitan areas Spatial modeling Geodata-management and geo-visualisation (Geodata infrastructure) Cooperation with research institutions on Campus Adlershof Institutes of the Humboldt University of Berlin Part.: Informatics, Chemistry, Psychology and centre of multimedia learning German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt DLR) Part.: research on traffic, geoscientific remote-sensing, applied remote-sensing 4
Research: remote-sensing Focus: Remote Sensing for mapping land-use and landcover (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 (knowledgeand rule-based interpretation, Support Vector Machines, Spectroscopy, radiative transfer model ) Applied research: Mapping Sealing in Berlin 5
Research: remote-sensing Metropolitan studies Project: Monitoring of the postsocialistic changes in Berlin on different levels of scale Landsat 5 data Lehrter Bahnhof (2005) DFG-funded Graduate School on Urban Ecology Shrinking Cities http://www.stadtoekologie-berlin.de Source: Diermayer 6
Geomatics Department - Humboldt-Universität zu 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 => applied research TU Berlin Prof. Dr. Birgit Kleinschmit HU Berlin Prof. Dr. Patrick Hostert Digitale Dienste Berlin Dr. Bodo Coenradie Source: Damm et al. 7
Analysis of hyperspectral data Schöneberg Mitte Source: Hostert/Schiefer Data: HyMap-data Objective: Methodical research to differentiate types of sealings => methodical research 8
Land-use/land-cover changes Analysis of forest cover and forest fragmentation changes in post-socialist times (+ drivers) Crossborder study: Poland, Ukraine, Slovakia Non-Forest Unchanged Forest Disturbance 1994 2000 Disturbance 1988 1994 Disturbance before 1988 Landsat ETM+ (June 2000) Source: Kümmerle 9
Land-cover/land-use mapping DeSurvey: A Surveillance System for Assessing and Monitoring of Desertification largest concerted research action on desertification and land degradation in Europe monitoring of land degradation effects with Landsat data in Mediterranean landscape funded by: EU-FP6 Overgrazed Quercus coccifera shrublands 0.5-2 m 5-15 m Source: Hostert/Sonnenschein Open Quercus coccifera forest 10
DHAKA-INNOVATE Informal settlements, economic and environmental change, and public health - Strategies to improve the quality of life in Dhaka (Bangladesh) => remote-sensing derived indicators and integrated GIS-based modelling Source: UNEP/GOOGLE Earth Berlin-Bielefeld Consortium DFG Priority Programme Megacities: Informal Dynamics of Global Change 11
Geodata management Remote Sensing = one important source of information for geographical research questions Integration with additional data Semantic/Syntactic interoperability within Geoinformatics 12
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 Berlin Warsaw Moscow 13
Geodata Infrastructure Geodata Infrastructure of the Geographical Institute The aim: Improving the access and availability of data within 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 http://gdi.geo.hu-berlin.de/ 14

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 16
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 17
Teaching Bachelor Introductions into Cartography and Geovisualisation Geoinformatics Remote Sensing Statistics Master Modules of Remote Sensing Geoinformatics Digital Image Processing Modeling Digital Photogrammetry Databases Hyperspektral data Distributed Systems Programminig (IDL )... Programming (VBA...) Geovisualisation... Statistics Geostatistics Multivariate statistics 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 19
