[RegCNET] Problem with Terrain

[M.Mahakur]

Hello all:

I am getting the following errors while using the terrain.x:

after calling RDLDTR
 after calling XYOBSLL
  rin,ds(m) = NaN         NaN        
  rin,ds(m) = NaN         NaN        
 after calling ANAL2
 after calling SURF
 LANDUSE MASK           0 exceed the limit

what could be the problem?

Regards,

Mahakur
