Lidar exploitation in water area detection

Question asked by hoctopusse on Mar 6, 2015

In wallonia we like to use LAS data to detect water. The final product should be a database of all potential water area (excluding  river) the main trouble i have is the water information itself. Some time the water is correctly detected some other is vegetation ...

 

I'd like to know if there is any tool to reclass ground point with intensity criteria ? That should help me to incrase  the point of with potential water pool because atm I can only work of water declared point or nodata area.

 

The final target is to see if potential water area can match with a depresision
