New here and I am using Pix4d Fields. I can generate plenty of maps but have no idea what they mean. is there somewhere i can reference to learn what they all mean and what i am looking at? Thanks!
You can have a look at these support articles: https://support.pix4d.com/hc/en-us/articles/hc/en-us/sections/360000139883-A-project-step-by-step
You will be able to see a scale showing the index values (example for NDVI range is -1 to 1) just below the index maps you have generated. Higher value for NDVI would mean healthy plants, and lower value would be stressed plants or any other features (like soil, road).
Can you say more about which maps you want to understand in detail?
I have several maps to choose from GNDVI, LCI,MCARI, Ect then I can click on each and it will give me red-green, Thermal, DSM, Ect. I don’t understand what the difference In configuration IE GNDVI-Red-green or GNDVI-DSM I don’t know what the different map values mean. Didn’t know if there was somewhere to so what the different combinations do or what any of it does.
For all these indices, GNDVI, LCI etc, there are vegetation indices. All these custom indices indicate about plant health and are a combination of 2 or more bands. They tell about the health of plants/crops/vegetation. When you click on the maps, you will see a scale bar below ranging from a minimum value to a maximum value showing colors. The lower values mean stressed plants (the stress can be because of irrigation, pests, diseases, nutrients anything). The higher value means in those areas the plants are healthy and you do not need to worry about them.
The red-green, thermal, DSM are just the color scales, you can choose any color you want. However, for vegetation indices, it is good to select red-green (it is kind of universal). If you have a look, you will see when you choose any of these, maybe thermal from red-green, the range of the color scale does not change. It is thus only a visualization tool.
