I'd like to extract road defects from a lidar point cloud. So, wherever a road surface drops or raises by a few mm relative to 100 cm around it.
I know it's possible but I just can't find or figure out a workflow for it.
Erdas Webinars has the workflow for version 2011, but this is very different in 2013 as it uses a raster .img file instead. I also looked at the workflow files from Imagine Help.
In ESRI it's a similar issue.
Any advise on workflows for this? We own both software so I would like to manually extract defects from a terrestrial LiDAR scan using either of these.
