I am trying to create a process to identify road defects manually from Lidar. We have Erdas 2013, ArcGIS10.1 and Global Mappper 14.2 as options for paid software.
So far Merrick Mars displays the data the best but (the free version) does not allow one to draw polygons.
With ESRI the best I could get is
Unfortunately you can't zoom any further to view defects.
With ERDAS the best I could get is
With Global Mapper the best I could get is I can manually assign a color to each range of elevation but this is very cumbersome.
So any ideas on what I am doing wrong? how can I get a similar view to Mars in any of the other software?
I need to then create a polygon around each road defect.
