Representing and modeling spatio-temporal uncertainty using belief function theory in flood extent mapping

作者:

Highlights:

• A new approach for modeling uncertain spatio-temporal information is proposed.

• Information with uncertain location and duration of floods are investigated.

• A set of spatio-temporal relations between uncertain flood events is introduced.

• Similar information about flooding events are merged.

• Experimental results show the accuracy and robustness of our approach.
