[GRASS-user] r.valley.bottom: a script to calculate a Multi-resolution Valley Bottom Flatness (MrVBF) index

[Helmut Kudrnovsky]

hi,

by r60920 I've added a very rough version of:

r.valley.bottom: a script to calculate a Multi-resolution Valley Bottom
Flatness (MrVBF) index

inspired by 

John C. Gallant and Trevor I. Dowling 2003. 
A multiresolution index of valley bottom flatness for mapping depositional
areas. 
WATER RESOURCES RESEARCH, VOL. 39, NO. 12, 1347, doi:10.1029/2002WR001426,
2003

testing and hints for improvements are very welcome ...





-----
best regards
Helmut
