Knowing your Limitations

I have recently prepared another article for LiDAR News titled Knowing your Limitations.  Understanding what a technology does not do is equally, if not more, important than understanding what it does do.  Where those limitations can affect the successful outcome of a project, other methods, tools or techniques are needed to compensate.  The article addresses some of the larger topics.  In upcoming posts, I'll provide additional items to consider when pursuing a Mobile LiDAR project.

The images presented in the article are shown below with captions:

Manholes:  In a span of 40' along a roadway, there are 6 manholes and two water valves.

Grass on Bare-Earth/DEM:  A random non-Federal levee shows the difficulty dense vegetation adds to determine bare earth along the bank.

Obscured Areas:  The area behind two parallel parked cars is obscured in comparison to the open area between them.  The shape of the voids depicted, represents the orientation of the lasers and varies based upon heading.
As always, please let me know if there are any topics you would like to see discussed.
