  • ISCRAM 2013: Design of a Process Model for Unmanned Aerial Systems (UAS) in Emergencies

    1. 1. 1 Design of a Process Modell for Unmanned Aerial Systems (UAS) in Emergencies Hans-Peter Thamm BT Geoconsulting and Mapping GmbH Thomas Ludwig, Christian Reuter University of Siegen
    2. 2. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 2 Introduction In case of natural disaster supply lines (e.g. electrical power) can be damaged • Strong disturbance of the life of population • Risk for people • Immense loss of money Goal: Quick restoration of supply lines
    3. 3. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 3 Research project 3 Goal: Development of an inter-organizational collaboration infrastructure „Security Area“ Learning Information structures for crisis management at the example of electrical power supply (2010-2013)
    4. 4. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 4 Introduction: Infostrom Project In case of disaster: Fast and efficient re-establishing of supply with electrical power. Therefore necessary: Suitable system for assessing sound information about the real situation and efficient communication between the different stakeholders. S S RWE RWE RWE RWE
    5. 5. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 5 Introduction: Infostrom Project Control room Service technicans Police Fire brigades THW MediaPower supply companies Information structure in case of emergency People Problem: Very much information with different level of relevance and spatial representation How to get sound information
    6. 6. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 6 Introduction: Infostrom Project Control room Service technicans Police Fire brigades THW MediaPower supply companies Information structure in case of emergency peopleExternal spatial information Sound external spatial information sources can help assess the real situation in a short time.
    7. 7. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 7 INFOSTROM: Workshops to assess the availability and demand on spatial data Organisation of Workshop with stakeholders “Demand on spatial data in case of disaster” • How can the data be distributed in case of disaster? • Which information channels are available? • Which media? • Where are urgent demands for spatial data? • Which spatial data are available? • In which data format they are accessible? Thamm
    8. 8. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 8 INFOSTROM: Workshops to assess the availability and demand on spatial data Results of the Workshop with stakeholders “Demand on spatial data in case of disaster” aerial photos in a very high spatial resolution showing the actual situation are very valuable tools. • High demand on spatial data representing the actual situation • Pre processed data preferred (e.g. road is free, area is accessible) • Information system must work even in harsh conditions • Information must be easy accessible and understandable
    9. 9. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 9 Disaster management: Role of high resolution remote sensing images In case of disaster: Necessity for actual aerial photos Source: WSL •Overview over the local situation •Assessment of the damages •Assessment of the accessibility to the damaged spots •Efficient management of the action forces (which damages, where to go, which roads are accessible, risks) Thamm
    10. 10. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 10 In case if disaster: Remote Sensing Sources of aerial photos in case of disaster “Classical methods” •Manned helicopter •Manned aircrafts New techniques: Unmanned aerial systems (UAS) Can be operated local. Very high spatial resolution - even small details visible. Time series can be taken – changes of the situation and progress of work can be documented Problem: Images for local situation are often not fast enough available. Time series expensive. Coarse spatial resolution
    11. 11. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 11 UAS: Different UAS types Multicopter Weight 1 kg – 5 kg Flight time 15-40 min Can be operated till 8 m/s wind speed Little payload No airstrip needed Weight 0.5 kg – 25 kg Flight time 30-120 min Can be operated till 30 m/s wind speed Needs air strip for landing Fixed wing Weight 12 kg -16 kg Flight time > 120 min High payload Can be operated till 7 m/s wind speed Air strip needed Parachute UAS Thamm Thamm Thamm
    12. 12. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 12 UAS: Properties General properties of UAS • Autopilot – flying along pre defined flight path – covering area • Manual steering possible • Live transmission of field of view and GPS to ground station • On board cameras • Fast mobilisation – take off after 15 min - 25 min after reaching the investigation sites Thamm
    13. 13. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 13 UAS: Process model How to integrate UAS in a general information system? Process model for use of UAS in emergencies UAS action forces collect aerial photos of hot spots Control room Demand for local information, Transmission of data to control room, information extraction out of the data. Distribution of the information to the service technicians and other stake holders • Where are the damages • Accessibility of roads
    14. 14. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 14 UAS: Process model Control room Prevention Action force UAS Suitable areas of investigation size, conditions Advanced multi criteria risk maps for different scenarios Possible air strips, useabe telecom- munication Encrypted com- munication system Choice and purchase of UAS Digital maps of area with additional information Flight permissions Local stored digital maps of area with additional information Continuous training Advanced update functions with time stamps Integration in encrypted information system
    15. 15. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 15 UAS: Process model Control room Response Action force UAS Weighting the demand of information request, area definition as vectors Decision if the information is sufficient Evaluation of the situation at the hot spot Choosing area of investigation Mission planning choosing UAS type Programming autopilot / start Orthophotos, object detection Live transmission of position and video stream Possibility of changing the flight path of mission in near real time Processing of images New flights Evaluation Requirement new details Regarding total situation, flight restrictions area implemented automatically
    16. 16. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 16 UAS: Process model Wrap up (after Disaster) Detailed assessing of the damages in high spatial resolution Evaluation of the operation • Institutional • Technical • Communication Comparison of the risk maps created before the operation with the real situation Hot list with improvements for the total systems
    17. 17. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 17 Challenges Limitations / challenges for the use of UAS Technical •Enlargement range of UAS •Improvement all weather suitability •More information about long term reliability •Fast image processing •Reliable broad band transmission Legal •General flight permissions •Autonomous flight beyond line of sight •Integration in general air traffic •Improved flight height
    18. 18. Hans-Peter Thamm, Thomas Ludwig, Christian Reuter 18 Challenges Summary •Structured assessment of demand on information in case of disaster from stakeholder •UAS for gaining up to date information are available •Process model for the integration of UAS in a communication system created (prevention, respond, wrap-up) •Deficits and challenges for the use of UAS in case of emergency evaluated •Outlook for further development of UAS given
