  1. 7th international Workshop on the "Cross-border Disaster eResponse in the eRegion: Interoperability of Information Systems of the Organizations Involved" DIGITAL GEODETIC DATA, BASIS FOR SUCCESSFUL DISASTER MANAGEMENT Sonja Dimova, PhD Agency for Real Estate Cadastre May 04-06 2009, Skopje

  2. DISASTER CLASSIFICATION 1.Natural disastersare events caused by uncontrolled acts of natural forces endangering the life and health of the people and animals and cause damage to property, cultural heritage and damage to the environment. Disasters generated from dynamic processes which occur under the surface (earthquakes, tsunami, volcano, eruptions) Disasters caused by meteorologicaland hydro meteorological phenomenon (floods, fires, strong winds, drought, avalanches…) 2.Technological disasters are: explosions, chemical leakage, contamination, biological disasters - epidemics..

  3. DISASTER/CRISIS MANAGEMENT (1)How to define? The disaster management is a discipline in which the involved parties are preparing for the disaster before it happens, during the disaster and the reconstruction after the disaster. (2)Successful management of the disasters highly depends from the availability , the dissemination and the effective use of the information. -Mechanism for providing services  monitoring, warning and decrease of damages -adequate access to information  avoiding overlap of different levels of users (3)Economic support  adequate attention to risk from the disasters, protection as well as disaster management reducing the human and economic losses

  4. STAGES OF THE DISASTER MANAGEMENT 3. Reaction/solution Evacuation routes 2. Readiness Models and simulations PARTICIPANTS: public and private sector, voluntary organizations, municipal organizations and individual citizens After disaster Prior disaster 4. Reconstruction Estimates of damages and sheltering 1. Protection planning Identification Zoning

  5. GEODESY AND DISASTER MANAGEMENT The establishment of safety measures which use advanced geodetic technologies contribute to the protection of the citizen, the land and the property, as well as minimizing the losses. -Technology for remote detection, meteorological satellites, communication systems and satellite navigation play a significant role in the support of the disaster management, provide accurate and on-time information and communication support. -Geo-positioned information from : satellites, topographic maps, cadastre maps, combined with other relevant data into one information system have the objective to evaluate and decrease the disaster risk, -Monitoring the movement of the earth’s surface by geodetic surveys (example: damns, artificial accumulations)

  6. POSITIONING OF GEODETIC DATA IN AN INFORMATION CELL Topographic maps/ cadastre maps with Information for potentially critical zones Satellite and/or aero photo images READINESS Evaluation of damages Help planning Population data Infrastructure /logistics

  7. Population Critical zones (floods) Use of land. /ownership Critical zones (earthquake) Traffic roads Hydro graphics Borderlines Electrical network DTM Water supply network Geodetic points Gas network Ortho-photo MULTI-PURPOSE USE OF CARTOGRAPHIC DATA  Basic cartographic data Theme data

  8. PROVIDING BASIC INFORMATION DURING PROTECTION PLANNING

  9. EARLY DETECTION OF FIRESGNSS, satellite/aero images

  10. Identification of the consequences caused by eruptions/ visualization of earthquakes Anticipation and simulation of earthquakes/monitoring (performing seismic measurements, simulations and plan for prevention) Satellite images of a volcano before and after eruption

  11. Visualization of a flooding zone in function of successful flood management Basis for visualization - ortophoto map and DTM

  12. Level of watermark - per zones Simulated time perspective Safety Measures Safety Measures Anticipation method - characteristics Anticipation of flooding zones in function of the time

  13. Potentially risky zone Supplementing with evacuation routes, etc Map of zones to be potentially flooded hill Evacuation routes Evacuation zone Map for management of the disaster- the flood Map for preventive protection

  14. Quality of the geo-positioned information Weaknesses: lack of data, inadequate scale and type, updateness.... Role of the surveyors: survey and mapping expertise to obtain quality data necessary for the successfull disaster managment Data quality: Source - the data source; Positional accuracy - accuracy of X,Y i.e. X,Y,Z location (geometric) Attribute accuracy – is accuracy in a thematic, descriptive or numeral value assigned to the event Completeness – is the assessment of the level of data completeness - lack/excess Logical consistency – topology building – data synchronization Semantic accuracy – is the data description quality/the text accuracy Update – time when the data is collected

  15. Hardware GIS Software Geodetic data base Geodetic data as GIS component GIS development: • Geodetic data (cadastre maps, topog.maps, ortophoto, aero/satellite images...) • Functional organization of the data into a data base and data maintenance/updating Strengths of the GIS • Mechanism for integration of data from various sources • analyses, planning and safety • On-time decision-making • Services to all involved subjects • Data distribution-WEB solutions

  16. GIS benefits

  17. Network access* users Spatial data policy Standards* Integration of a GIS on a national level NSDI (National Spatial Data Infrastructure) • Scope of the NSDI • electronic spatial data from the bodies of central government, the local self-government units, the public services and legal advisors entrusted with the spatial data management Types of spatial data in the NSDI • Survey, cadastre and cartography • Protected zones, national parks, historic monuments • Statistical data • Spatial planning • Environmental protection NSDI-basic model NSDI Functionality Establishment of meta data, spatial data maintenance, Networking technology*, access, sharing and use of the spatial data* and mechanism for coordination steps and procedures *link

  18. Internet communication GEOPORTAL REGIONAL DATA NSDI CENTRAL GIS Relation: NSDI - disaster management AREC is obliged to establish and maintain the public access to metadata via internet (accessibility of easy and a secure method, time saving and finance for data development and maintenance) WEB GIS users GIS FOR DISASTER MANAGEMENT Analyses planning AREC GIS applications

  19. Public Campaign (awareness raising) • Institutions - defining a clear role and the connection to the successful collecting, processing, archiving, integration and sharing of spatial data • Tasks and Responsibilities • Trainings for: use of maps for disaster management, development of new maps for evacuation together with the local population and other representatives • Training and education program - workshops where the evacuation plan will be discussed • Using the media and the school centers • Pamphlets, brochures • Capacity building at a local and a regional level

  20. Urban planners Local tourists Citizens Medical institution Engineers Fire protection Trainers Participants in the workshop LOCAL SELF-GOVERNMENT -Chair- Example for a workshop Encouraging the local population to participate in drafting the evacuation plan and discussion for its use

  21. Conclusion The successful crises management mostly depends from the accessibility, the dissemination and the effective use of the spatial data Establishment of mechanisms foron-lineaccess to geodetic data which will be the basis for: monitoring, warning, damage assessment as well as reduction of the disaster consequences Use of standards, interoperability systems and techniques during the collecting, processing, archiving, integration and sharing of the digital geodetic data On-time delivery/providing with updated and accurate digital geodetic data on a local, national and global level Communication support which is made via the systems for communication, navigation and positioning
