topic Sinkholes from contours in Mapping Questions https://community.esri.com/t5/mapping-questions/sinkholes-from-contours/m-p/209628#M2217 <HTML><HEAD></HEAD><BODY><SPAN>Hi</SPAN><BR /><BR /><SPAN>I'm new to this forum so I don't know if this is the right place to post this so if you know a better place please direct me there.</SPAN><BR /><BR /><SPAN>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. </SPAN><BR /><SPAN>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.</SPAN><BR /><BR /><A href="http://geomorphometry.org/system/files/LiangDu2013geomorphometry.pdf">http://geomorphometry.org/system/files/LiangDu2013geomorphometry.pdf</A><BR /><BR /><SPAN>Thank you very much.</SPAN><BR /><BR /><SPAN>Ales</SPAN></BODY></HTML> Fri, 01 Nov 2013 09:26:27 GMT GrljAles 2013-11-01T09:26:27Z Sinkholes from contours https://community.esri.com/t5/mapping-questions/sinkholes-from-contours/m-p/209628#M2217 <HTML><HEAD></HEAD><BODY><SPAN>Hi</SPAN><BR /><BR /><SPAN>I'm new to this forum so I don't know if this is the right place to post this so if you know a better place please direct me there.</SPAN><BR /><BR /><SPAN>For my diploma I'm trying to compare differnt methods of sinkholes extraction.
