Open GeoSpatial Data as a Source of Ground Truth for Automated Labelling of Satellite Images

Marjan Alirezaie, Martin Längkvist, Andrey Kiselev, Amy Loutfi
2016 International Conference Geographic Information Science  
In this paper, we summarize the practical issues met during our interaction with OpenStreetMap for the purpose of automatically generating labelled data used by data classification methods.  ...  For instance, given a satellite imagery scene containing several objects, a pixel-based classification method may need a ground truth in the scale of the scene's number of pixels, whereas a ground truth  ...  Providing a reliable and precise ground truth for large city-wide size satellite imagery data on a pixel-level is non-trivial and time consuming.  ...
