Onions!

Agriculture

We’ve got a field that has onions. NDVI isn’t very helpful because there is a lot of soil and not so much crop. I’ve been researching and there is an index called SAVI (Soil Adjusted Vegetation Index) which disregards the soil in the calculations. I can’t see this as an option in Pix4D Fields, has anyone got any suggestions?

Many thanks
Chris

Hi, Osavi formula is (1+0.16)*((nir-red)/(nir+red+0.16)) you can insert it by visiting “Create custom index”
