Today – A myriad of geospatial data sources Today – A myriad of geospatial data sources and producersand producers

Thousands of Data SourcesThousands 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
Arctic Sensor Web PlatformArctic 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 PlatformArctic 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

• The Platform is based on OGC SensorThings (a candidate standard being advanced in the OGC for 2015 adoption)
• Jurisdictional differences in law and policy for the above
