  • 1. DIGITAL GEODETIC DATA, BASIS FOR SUCCESSFUL DISASTER MANAGEMENT Sonja Dimova, PhD Agency for Real Estate Cadastre May 04-06 2009, Skopje 7th international Workshop on the "Cross-border Disaster eResponse in the eRegion: Interoperability of Information Systems of the Organizations Involved "
  • 2. DISASTER CLASSIFICATION 1.Natural disasters are 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 meteorological and 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 PARTICIPANTS: public and private sector, voluntary organizations, municipal organizations and individual citizens 2. Readiness Models and simulations 1. Protection planning Identification Zoning 3. Reaction/solution Evacuation routes 4. Reconstruction Estimates of damages and sheltering Prior disaster After disaster
  • 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 READINESS Evaluation of damages Help planning Infrastructure /logistics Population data Satellite and/or aero photo images Topographic maps/ cadastre maps with Information for potentially critical zones
  • 7. Basic cartographic data Theme data MULTI-PURPOSE USE OF CARTOGRAPHIC DATA  Ortho-photo DTM Geodetic points Borderlines Hydro graphics Traffic roads Use of land. /ownership Gas network Water supply network Electrical network Critical zones (earthquake) Population Critical zones (floods)
  • 8. PROVIDING BASIC INFORMATION DURING PROTECTION PLANNING Disaster Protection Data collection Planning/ warning Earthquake Geological maps and Maps for land use Geodynamic surveys Identification of potential zones, Production of map for the possible disaster Eruptions Topographic maps (land use) Measuring of gas emissions Mapping of the lava and the measurements, Production of map for the possible disaster Land slide Topographic maps (land use) Measuring rains and surface stability Mapping of surveyed data and analysis Floods Topographic maps (land use) and Maps of flooding zones Measuring: rains, water surfaces and evaporation Mapping of data and supplementing with zone predictions Rains /Storms Topographic maps (land use) Measuring of rains Supplementing the map with the measurements and the predictions Droughts Topographic maps (land use) Measuring of temperature, Climate models Supplementing the map with the measurements and vegetation monitoring
  • 9. EARLY DETECTION OF FIRES GNSS, 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. Anticipation method - characteristics Anticipation of flooding zones in function of the time Safety Measures Simulated time perspective Level of watermark - per zones Safety Measures
  • 13. Map for preventive protection Potentially risky zone Map of zones to be potentially flooded Map for management of the disaster- the flood Supplementing with evacuation routes, etc hill Evacuation zone Evacuation routes
  • 14. Quality of the geo-positioned information
    • 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
    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
  • 15. 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
    Software Geodetic data base Hardware GIS
  • 16. GIS benefits Phases of the disasters GIS solutions Benefits Planning GIS maps for disasters, damage assessment by using GIS Easy maintenance, different formats, online access, tool for improving the capability, description of the risky zones and consequences Mitigation Municipal zoning and defining safety zones Preparedness for a short time and putting efforts for standard development Readiness Development of a scenario, models and simulations Anticipating and planning, development per zones and risk reduction, preparation and training Solutions Evacuation routes and safety management Fast identification of the routes, alternative routes, data related to safety Reconstruction Damage assessment and help for the population Accurate data base, geo-referenced information
  • 17. Integration of a GIS on a national level NSDI (National Spatial Data Infrastructure )
