4 Founding the concept Digital Earth Digital Earth (Craglia et al. 2012): development of development of systems innovative concepts for which would allow users integrated systems which to navigate through space make it possible to find, and time, accessing visualise and make sense historical data as well as of vast amounts of georeferenced information on would support its use by future predictions, and physical and social scientists, policy-makers environments and laymen alike.

9 Integrated Monitoring Systems: Concepts and Approaches DIMS Module of Remote Sensing and GIS Integration Course 2013 Lammert Kooistra and Martin Herold Laboratory of Geo-Information Science and Remote Sensing Wageningen University

10 Some definitions Measurement: direct observation of a phenomenon (measuring length in m) Monitoring: to be aware of the state of a system, repeated measurements to analyze changes Need to measure and monitor a phenomenon to properly manage it Often not a direct relationship between what can be efficiently and cost-effectively measured and monitored and the phenomenon and its societal benefits (e.g., biodiversity)

11 Monitoring for a reason Monitoring happens for a reason -> societal benefit Clearly defined objectives, users and uses are essential for efficient monitoring the perfect is the enemy of the good

13 Developments in Remote Sensing Long term time-series Range of sensor types Range of products and services Global organization and cooperation Improved (web-based) accessibility Also for non-experts Standards and quality control Near-real time availability Development of early warning systems

14 Developments in Geo-Sensor Networks Traditional: Broad range of sensor networks Stable and well organized Often not real-time (manual or datalogger) Trends: Miniaturization of microelectronics Wireless communication Developments of new materials & sensors Consequences: Embedding devices into almost any manmade and some natural devices, and connecting the device to an infinite network of other devices, to perform tasks, without human intervention. Information technology becomes omnipresent. Source: Nittel, Sensors, 2009 Crossbow Mica Mote

15 Developments in Mobile Sensing All kind of platforms combined with different sensor types Difficult accessible areas Disaster monitoring (flexibility) Mobile processes: traffic jams or animal tracking Increasing autonomy of sensor network Adaptive learning Developments in human sensing: Use of mobile phones Citizen observatories Crowd sourcing

18 Concepts for spatio-temporal data organisation Digital Earth (Craglia et al., 2012): a multi-resolution, three-dimensional representation of the planet that would make it possible to find, visualise and make sense of vast amounts of geo-referenced information on physical and social environments Sensor Webs (Teillet, 2010): a system of autonomous, wireless, intra-communicating, spatiallydistributed sensor pods that can be deployed to monitor and explore new environments, a smart macro instrument for coordinated sensing Global Earth Observation System of Systems (Lautenbacher, 2006): The focus of GEOSS is to produce societal benefits through more coordinated observations, better data management, increased data sharing, and application to societal needs.

19 Global Earth Observation System of Systems: GEOSS A Global, Coordinated, Comprehensive and Sustained System of Earth Observing Systems GEO is a voluntary partnership of 72 governments and the European Commission, 52 intergovernmental organizations (Feb 2008) User driven approach Interoperability arrangements Web portal and clearing house Support new observation methods Dissemination knowledge source:

How much and where? What are the mitigation options? What does it cost? What are cheap, replicable indicators? Who is not complying to the mitigation? Is the problem properly address?

28 Planning of activities

29 Specification of use case Management of historic objects: buildings, trees Forest management Tourist streams and recreation Changing land-use patterns Sustainable energy Protecting national landscapes Nature conservation

30 Data management plan Combination of broad range of (geo-)datasets Organize and manage these data-sources Description in Data Management Plan: The types of data, software and other materials produced; The standards to be used for data and metadata format and content; Policies for access, sharing and ownership of data and products; Plans for archiving data, software and other research products, and for preservation of access to them. Common approach for both science and industry projects Format will be provided

31 Fieldwork plan An important component of the Digital Earth concept is the availability of real-time and actual data. Based on availability of (open) geo-datasets, a selection of new geo-data sets will be acquired Prepare fieldwork plan based on case study Execute fieldwork plan and prepare datasets for publication Separate presentation

32 Publication of geo-data and acceptance test A Digital Earth application should enable open access to geo-data (key element 5 and 7) publish a selection of 3-4 key datasets from the fieldwork collected data through a Web Mapping Service (WMS) -> ArcGIS Online (or alternative) acceptance test needs to be followed in order to ensure the quality of the dataset according to specific geo-data standards. More background in presentation John Stuiver

33 Usability strategy Evaluate user needs and requirements in relation to visualization approach More Background in presentation of Ron van Lammeren

34 Final implementation and visualization in presentation (1) Presentation of the Digital Earth application: The relevance of case study for the Living Lab the Reirinck; The intended users and their profile; Selection of newly acquired data-sets; Usability strategy; Developed demonstrator Including a demonstrator of the visualization approach: focus on the user-interface and an overview of the functionality where especially the combination of existing (open) geo-data sources and the newly acquired data should be presented.

35 Final implementation and visualization in presentation (2) The presentation should fulfil the following requirements: Presentation 20 minutes Discussion 10 minutes Audience: potential users specified for the Digital Earth application Presentations be at the Reirinck on Monday June 12 You could use the actual surroundings in your presentation and present the demonstrator in a field situation making use of for example a mobile platform.

36 First phase of assignment Specification of Use Case for Digital Earth application Every team, prepare short presentation (max. 4 slides, max. 5 minutes): What are current developments around the Living Lab the Reirinck (see description in Appendix 1)? Who are the stake-holders in these processes? What are the (geo)data requirements? What would be possible ways to present/visualize this to end-users? And of course, very important what is the personal interest and motivation for the team? Present during feedback session, start 15:30 this afternoon (lecture room C0093)
