Hi

For my diploma I'm trying to compare differnt methods of sinkholes extraction. For this purpose I would like to automaticly extract sinkholes from contours shapefile. While I succesfuly extracted the lowest contour of the sinkhole I have no idea how to select/extract the second, third... if a sinkhole has it.
Any suggestion will be more than welcome. Although I came across an article I do not fully understand the method used so I'm also posting a link to that article if anyone has time to check it and possibly exsplain something to me.
