The csv table is not that intuitive, I have tried to make it as compact as possible…
[1,1:2] = centre of selection lon lat
[1,3] = Na
[1,4:ncol] = the date in days since 0 of the image, the intervals do not have to be equal, it depends on the image date.
That [1,3] shows a NA value is because, the values beneath it are not part of the time series, these are the mean velocity values, used for colour coding!
[2:nrow, 1:2] Measurement Points lon lat
[2:nrow, 3] mean velocity
[2:nrow, 4:ncol] cumulative displacement values
