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)
Monitoring for a reason
Monitoring happens for a reason -> societal benefit
Clearly defined objectives, users and uses are essential for efficient monitoring

Developments in Geo-Sensor Networks
Traditional:
● Broad range of sensor networks
● Stable and well organized
● Often not real-time (manual or data-logger)
Trends:
● Miniaturization of microelectronics
● Wireless communication
● Developments of new materials & sensors
Consequences:
● Embedding devices into almost any man-made 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.

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

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, spatially-
distributed 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.’
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)

Assignment description
Develop a reproducible Digital Earth application for a specific Use Case present in the Living Lab the Reirinck
Combine open geo-data sources with own measured geo-data;
Make use of 3D visualization elements and data sources;
Publish newly acquired data-sets as open data sources and document data quality;
Prepare and present a visualization demonstrator based on a specified usability strategy.

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