I selected the Landsat 8 data, I wanted to draw time series of NDVI for a crop field, I uploaded KML polygon but when I wanted to draw FIS chart the graphs did not appear and said: “no data found”.
For the Sentinel 2, it works well but I need to draw FIS chart of NDVI derived from Landsat 8.
Can you be more specific in where you have tried this and how?
I just checked this option on a random location and it worked OK for me.
Landsat resolution is 30meters so one pixel has an area of 0.01 px… If you are close to this, it will certainly not work.
This is a screenshot of the area, I wished to share with you KML file but as a new user and cannot upload the attachment. Probably the area is very small (0.01 km^2). For the bigger area polygons, it works but not for the smaller ones, less than 0.4 km^2.
