Interoperability
• Defined as the ability of diverse systems,
applications and organizations to work together
(inter-operate).
• Affords us opportunity to save time, reduce cost,
increase flexibility, protect assets and lives

Today – A myriad of geospatial data sources
and producers

Thousands of Data Sources
• The number of sources of
GEO data is increasing
geometrically, e.g
–
–
–
–
UAVS
Mobile Devices
Citizen Scientists
Increase in Space borne and
airborne sensors
– CCTVs, Flood gauges
• In many cases there are
untapped resources
• Increasing complexity

VGI / Crowdsourcing Observations
• Inclusive - everyone can participate and contribute, gives a
great sense of contributing to society
• Additional, often critically important data, can augment and
shape authoritative data
• Often minimal provenance and data quality indicators
• Works well for it’s original purpose, but often difficult to
repurpose (lack of metadata, cataloging)
• VGI can be user observed or feeds from user established
sensors / IoT
• Standards can support and simplify VGI capture,
processing and integration

Advancing Mobility - OGC GeoPackage
• The OGC GeoPackage standard is a universal file format
for geodata.
– open, standards-based, application and platform
independent, and self-describing.
– Works on any desktop or mobile OS
– For use in a connected / disconnected environment
• GeoPackage - the modern alternative to
formats like GeoTIFF, SDTS and vendor specific
• Experience it here:

Mediation and Conflation
• Identification Feature conflation
– Is it the same feature?
• Semantic Inconsistencies
– Name of the feature
– Name of the attributes
• Geometric Conflation
– Points matching
– Polygons matching

Arctic Sensor Web Platform
• Challenges for Arctic Geospatial and Sensor Data
–
–
–
–
difficult and costly to collect data
coverage is sparse
data are not updated
one area, many countries
• As a result, data sharing becomes critical!!
– example: Arctic Spatial Data Infrastructure (ASDI)
• The Arctic Sensor Web Platform provides easy-to-use tools allowing
ANYONE to publish and share their sensing devices over the Web via
interoperable OGC interfaces.
• Funded by GeoConnections, developed by SensorUp Inc. (a University
of Calgary startup)

Arctic Sensor Web Platform
• Base map is based on Open Street Map data
– use VGI to solve the data sparsity problem
– server live-synced with OSM database, latest updates are synced within
minutes
• Note that map tiles are NOT in web mercator projection
– currently available in six different polar projections

Arctic Sensor Web Platform
• The Platform is based on OGC SensorThings (a candidate standard being
advanced in the OGC for 2015 adoption)

Need for Policy and Legal Frameworks
• Some Considerations:
–
–
–
–
–
Ownership
Intellectual Property Rights
Licensing Terms
Liability
Privacy
• Jurisdictional differences
in law and policy for the
above
