Modified: 1-27-2021 Hello, we are updating some information according to your questions. Besides the generation of standard vegetation indices, the use of the index calculator allows us to generate a custom index that adapts better to their specific crop scouting or crop protection needs. Some of…

So you will need to use this: (nir-red)/(nir+red) + 0/min(0; (nir-red)/(nir+red) - 0.8). That will mask all the vegetation NDVI ranging from 0.8 to 1. The range of max, min in zonation maps will not be there yet. However, I will pass on the request to our team. Could you also make a feature request…

great, but how about if the vegetation that i wanted to mask was only between 0,8 to 0,9?

You will not be able to do it with this formula but as I said, this feature is coming very soon. For now, you can try it in QGIS. You will be able to chnage the max, min values of the map.

Hi, For this function, How can calculate the soil mask area size of total? For example, the soil mask all soil, then how many percentage of total NDVI? Thank you.

Is that possible to use zone function to calculate the area of soil?

You will get an estimation but we havent tested it, so I would not recommend it at this moment. You can give it a try. First mask the vegetation, and then generate a zonation map and see the area. But for now, to be sure I would recommend using QGIS.

[image] Fernanda_Bosmediano: (nir-red)/(nir+red) + 0/min(0; (nir-red)/(nir+red) - 0.4) Hi, Is there a way to reduce size of zonation? for example i’m trying to generate a zonation map for where individual weeds are, however zonation does huge areas instead. I’ve tried the formulas above which…

Unfortunately not inside PIX4Dfields. However, you can take out outputs and do that with QGIS for example. Maybe this gives you an idea of the workflow: 86960 - Google Drive

Hi, How to use the grid zonation map of QGIS in the video convert to a shape file with data (amount, area_ha, avg Value, rate_ha)as like Pix4dfields prescription map?
