2- PROBLEMS


 
The Windows interface's code is not available, but the interface is free. A command line version of 5-SCALE is available in C.
Some known "problems" with the interface:
  • The number of simulations that can be done and viewed has been increased (on a PCs with 128 MB of ram memory, the number of simulation is very high and should not be a problem, but on a PC with only 32 MB, 3-4 simulations can be enough to get a blank screen). As new PCs get more and more memory, this is less of an issue now. [January 2001]
  • When running a second simulation in the USER DEFINED mode, the display is sometimes erroneous: a points that was not simulated sometimes appears. [October 1, 1999]
  •  The "Nadir function", which was added in 4-Scale 3.1 (and 2.5.1),  has not been validated for SZA less than 20 deg.  [October, 1999]
  • The proportion of sunlit foliage seen on one crown (Pti) is not always "smooth" near nadir. This does not affect much the final result, but may need to be fixed. [May, 2000]
  • The HEMISPHERICAL mode may experience problems if another mode was used before [January, 2000]
  • Althought LIBERTY is integrated into 5-Scale, you need to re-run it everytime you run a simulation in the hyperspectral mode. [March, 2001]
