Greeting
I have got serious problem
with "IFF" function.Actually I have three raster map ,now (may be increased to 4
later) with the same georefrence and all of them having class domain
(map1=Canopy cover, map2=Erosion, map3=EC).I want to produce new map
(Desertification map) with new class domain, for this I should use "IFF"
function more than one time.I have no idea how can I prepare this script or
function.For example I want to tell ILWIS : Iff map1 have class "IV" and map2
have class "V" and map3 have class "III",then return class "SEVER" for new
map(desertification map) and iff map1 have class "I" and map2 have class
"II" and map3 have class"III", then return class"LOW" for the new map and
so...I have tried some functions but I got error. May be I made a mistake
in the number of parenthesis or some things else. I am new with this kind of
work, so it would highly appreciated if you help and guide me in this
issue.
Thanks in
advance
