I am using LiDAR data to locate Sinkholes(depressions) in an area. I am doing this by making the contours and checking the contours(if they are circular enough or not, elongatedness, etc.). But I have a problem, I need to check the jaggedness of the circle edge, so If it is too jagged, I eliminate that contour. Any idea how can I do that?
Better to use the sink tool in the spatial analyst toolbox to identify sinks in a raster surface. Still, if you are dependent on the jagged polygons idea...ensure that the attribute table is populated with the lengths of the jagged lines Generate a 1 meter buffer around the polygons, then calculate the lengths of the buffers. Compare the two lengths. A higher difference in lengths means a more jagged polygon.
