[GRASS-user] Feature extraction in GRASS and Landserf.

[Marcello Gorini]

Dear all,

By comparing morphometric feature maps obtained from both "r.param.scale" in
GRASS and the function "sufparam" using LandScript in Landserf (Wood,
1996-2009), I noticed great discrepancies.

Actually, a morphometric feature map derived in GRASS using slope tolerance
of 3 and curvature tolerance of 0.000003 is similar (visually) to a map
derived in Landserf using 3 for slope and 0.05 for curvature.

After consulting r.param.scale manual and Wood's documentation I am still
clueless. 

Can anyone help me in this issue?

I am using GRASS 6.4.0SVN and Landserf Version 2.3.

I thank you all very much in advance.

Best regards,

Marcello Gorini.
