- •
A localized contour tree method was proposed for automated extraction of sinkholes.
- •
Sinkhole boundaries were automatically delineated.
- •
Hierarchical relationship of sinkholes was represented using contour tree graph.

More than 30% of the inventoried sinkholes were filled due to agricultural use.
- •
The sinkhole database significantly underestimated the number of active sinkholes.
