The July/August 2016 issue of Geoconnexion magazine features an article on data conflation, authored by consultants from the Applied Research group at Envitia. The article explains how crowdsourced geoinformation can be conflated with authoritative datasets to realise enhanced products.
The article concludes that the benefits that data conflation of crowdsourced and authoritative information bestows can be summed-up as:
- Lower survey costs per sq. km of data
- Potential for near real-time updates
- High density observations from a large number of sensors (users)
- Coverage of global regions where authoritative data is sparse, or not available
- A growing crowdsourcing community
- The ability to enrich authoritative datasets with information pulled-through from crowdsourced sources
The article will be of interest to anyone looking to get the best out of their data assets and the wealth of volunteered geographic information that is available from crowdsourcing sites such as OpenStreetMap.
