Volunteered data for Earth Observation archive enrichment via heterogeneous mining
Abstract
Semi-automated content-based semantic data enrichment represents a possible strategy for increasing the applicative value Earth Observation represents. To this end, devising a scientifically principled and effective way of soliciting and integrating volunteered ground truth data with varying degrees of believability as supervision to thematic mapping systems is a problem of significant theoretical and practical interest. We consider a probabilistic data integration and fusion strategy, and conduct a preliminary evaluation activity based on public micro-blogging streams and on ad-hoc recollected data to try and validate the approach. A limiting factor is represented by the disparate attainable precisions in basic parameters such as geo-location. A further point of interest is represented by the foreseeable effects that the implementation of such a strategy would have on acquisition scheduling.
