I am interesting in getting the NDVI values inside a region. I was able to do a request using FIS as explained here
But I would like to know how many pixels are being used inside the region I defined, for the statistical calculation. Is that posible? how?
Thank you for your answer,
I count them using ‘bins=5’ and the total is not an integer (total=170.828125 pixels). Does it means that my region has almost 171 pixels? why is not an integer?
Another related question:
what if I mark a “point of interest” in the eo-browser? How and which pixels are used in that case? I see squares in the layer, and I thought it was a single pixel, but I can mark the “point of interest” in different places inside each square and it gives different statistical values. Also, in the graph, it says “mean”, but…the mean of what values?
Yes, the above is 171 pixels. The “not integer” might be due to your AOI not intersecting exactly with pixels. Or simply due to statistical approximations.
EO Browser takes, if I am not mistaken, an area of 10x10 meters if you choose point option. So by clicking on various parts of the pixel, you will take also some of the neighborhood pixels into account.
