Is it possible to have features on Pix4Dfields or Pix4Dcloud like plant count, plant health monitoring such us Plant Stress Analysis, Weed Analysis, Pest Analysis, Drought analysis etc.? So we can easily analyze and monitor our crops?
Thank you for your interest in our Pix4Dfields software. Regarding your questions:
In respect of plant counting, we do not have this feature into our Pix4Dfields 1.4 software for now, but it is definitely into our roadmap.
Regarding plant health monitoring. Using Pix4Dfields we have a list of available indices that you can see here, we also give the option to customize the indices depending on our user’s needs. Some of the available indexes are the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Red Edge (DRE).
In most studies, plant stress analysis is depicted in the NDVI vegetation index. Stressed crops will have less NDVI than crops that are healthy. The content of chlorophyll can also indicate the health of the plant since these contents take part a direct role in photosynthesis, so the DRE index might be helpful for you as well. Also, some pests cause the loss of chlorophyll in the plants, so this index can be also used for pest analysis.
The uses of the indices will always depend on your interestest. After generating the index, and for monitoring what our users normally do is they generate zones and use the prescription tool.
Let’s say that I would like to see my area of interest in 3 zones based on my NDVI, so I get this:
The zonation and prescription tool is designed for fields where you are looking to produce variable rate application maps for machinery (e.g. fertilizer spreaders, seeders, etc.) In this example, (red areas) I know from my NDVI that the plants are not so healthy, so I will add more fertilizers, and I will add less fertilizer in the yellow areas because my NDVI showed me that they were good.
In this link, you can see some of the user cases using Pix4Dfields that might also help you.
I hope this information was helpful to you. Let us know if you have more questions.
