    GIS, Mash-Ups and Geographic Standards GIS, Mash-Ups and Geographic Standards Presentation Transcript

    • GIS, Mash-Ups and Geographic Standards: Appropriate Mapping and Analysis Tools for Situation Rooms Beate Stollberg Joint Research Centre of the European Commission, Institute for the Protection and the Security of the Citizen, Global Security and Crisis Management UnitISCRAM Summer School 2011Tilburg, 22.08.2011
    • Overview European Civil Protection GIS Geographic Standards Mash-Ups Summary and Conclusion GIS Lecture ISCRAM Summer School 2011 2
    • European Civil Protection Crisis Management Laboratory at JRC Data collection (live media/web, own data) Validation and processing Presentation and dissemination Situational awareness and political response Advisory role GIS Lecture ISCRAM Summer School 2011 3
    • European Civil ProtectionThe Monitoring and Information Centre (MIC) Operated by the EC in Brussels Heart of Community Mechanism for Civil Protection Available 24/7, duty officers on shift Any country (inside or outside the EU) affected by a major disaster can launch a request for assistance through the MIC GIS Lecture ISCRAM Summer School 2011 4
    • European Civil ProtectionMIC during emergencies: Communications hub Information provision Supports co-ordination Map Report GIS Lecture ISCRAM Summer School 2011 5
    • European Civil ProtectionExample Map GIS Lecture ISCRAM Summer School 2011 6
    • European Civil ProtectionIn 2010 Critech produced crisis maps during thefollowing 11 disaster events:12.01.2010: Earthquake Haiti 30 maps27.02.2010: Tsunami Chile 14 maps14.04.2010: Volcano Iceland 1 map20.05.2010: Flood Poland 3 maps06.07.2010: Flood Moldova 1 map03.08.2010: Flood Pakistan 42 maps03.10.2010: Chemical Spill Hungary 5 maps18.10.2010: Typhoon Megi Philippines 1 map25.10.2010: Tsunami Sumatra 1 map05.11.2010: Hurricane Tomas Haiti 3 maps19.11.2010: Cholera Outbreak Haiti 5 maps GIS Lecture ISCRAM Summer School 2011 7
    • European Civil ProtectionGeo-Information related Requirements  Event-specific geographic information  Places Finding  Best available background maps  Spatial analysis  Map images (“Screenshots” for briefing reports)  Detailed (printed) maps Mapping  Shared (digital) maps with real-time information  Collaborative mapping Archiving  Store data GIS Lecture ISCRAM Summer School 2011 8
    • GIS Development of GIS (I)1980s >> first commercial GIS vendors (e.g. ESRI) >> complex closed applications1994 >> Open Geospatial Consortium (OGC) founded >> development of common standards2000s >> Interoperable Service Oriented Architecture (SOA) Spatial Data Infrastructure (SDI) GIS Lecture ISCRAM Summer School 2011 9
    • GIS Development of GIS (II)2005 >> Google Earth >> First time maps and satellite images of the whole world were freely available >> Mash-Ups >> often including maps >> User Generated Content (UGC) >> often including location (cheap GPS devices) >> Location Based Service (LBS) WEB 2.0 GIS Lecture ISCRAM Summer School 2011 10
    • GISA Geographic InformationSystem (GIS) is designed tocapture, store, manipulate,analyze, manage and presentall types of geographically Processingreferenced data.In the simplest terms, GIS isthe merging of cartography,statistical analysis, anddatabase technology. Data(base) GIS Lecture ISCRAM Summer School 2011 11
    • GIS Mapping the real worldFigure from: http://giscommons.org GIS Lecture ISCRAM Summer School 2011 12
    • GIS Modeling and analyzing the real world Concept of “Features” Figure from: http://giscommons.org GIS Lecture ISCRAM Summer School 2011 13
    • GISExample: Point-in-Polygon Analysis (Even-Odd-Rule)  Odd number of intersections >> Point inside  Even number of intersections >> Point outside GIS Lecture ISCRAM Summer School 2011 14
    • GIS Figure from: http://giscommons.orgGIS Lecture ISCRAM Summer School 2011 15
    • GIS Raster data  Grid-cell data structure  Location of a cell is identified by row and column  Each cell (pixel) has an assignedFigure from: http://giscommons.org value  “Easy” creation from image data, e.g. satellite images, scans Resolution determined by pixel size Efficient representation of dense data, e.g. elevation GIS Lecture ISCRAM Summer School 2011 16
    • GIS Vector data  Features are presented by points, lines and polygons  Each feature may have many assigned values (attribute data)  “Complex” creationFigure from: http://giscommons.org Efficient representation of discrete data Topology creation possible GIS Lecture ISCRAM Summer School 2011 17
    • GIS Topology = Spatial RelationshipsFirst law of geography: “Everything is related to everything else, but nearthings are more related than distant things.” Distances between features Adjacency of features Connectivity of features GIS Lecture ISCRAM Summer School 2011 18
    • GISSet of topology rules Each edge has two nodes Each edge has an area on the left and right side of it Each area is enclosed by edges and nodes Each node is enclosed by edges and areas Each line crossing is a node GIS Lecture ISCRAM Summer School 2011 19
