How did you calculate the NDVI?
Does the metadta re-appear when you enter the start/stop time according to the requested format?
The exact hour and minutes should not matter for the time series tool but the full time must be entered in a correct format, e.g.:
Yes!!! I did as you explained and now it works!
The problem was that I was creating the NDVI as independent maps and not as an extra band of the same image…it seems that it makes a difference.
Many thanks for your time and good explanations.
-A final question: what would be the best way to export ONLY de NDVI’s as GeoTIffs ??
I tried your workflow many times but it didn’t work. Then I created NDVI images as below and tried again but still doesn’t show the time series. It only shows only curser when it is on. (All vector polygons are imported to all NDVI images).
Because of the problem I mentiened above, I extracted all NDVI values manually from EO Browser but I dont know how to integrate those values with my SAR images and classify together. Is there anybody have any suggestions? I have to solve this problem before weekend
I have a problem to give the same name for all products.
I downloaded all the products (a mix of S2A and S2B in the same area over 1 year). I opened them in SNAP. Right clicked on the product, in Product Explorer window > band maths. The first I could name ‘NDVI’ and create a new band (not virtual expression) using the NDVI calculation. However, it doesn’t work for subsequent products.
The error says: “The band name must be unique within all product scopes”.
Are there some other pre-processing steps to do before using the band maths tool? Coregistration, making a spatial subset, or band subset, or collocation perhaps? My computer memory is also getting overloaded when I try to use the time-series tool.
So far I have the time series graph working for the cursor position with Band 8 and Band 4 separately, but not with them combined as an NDVI.
