Dear all,
Im currently doing my research in NDVI index.
As some of you might know the NDVI forumula is based as following
NDVI = (NIR-VIS)/(NIR+VIS)
Where
NIR = the ratio of reflected light/incomming light near infrared (NIRref / NIRin)
VIS = the ratio of reflected light / incomming light Visible (VISref/VISin)
about a year ago i mathematically constructed the following formula
NDVI = ((VISin/NIRin) * (NIR-VIS)) / ((VISin/NIRin) *(NIR+VIS) )
I know this is mathematically correct. however ofcours i lost my notes.
and i cannot find the way is solved it last time.
Can anyone help me with this?
Thanks in advanced!
Ralf Smit
