Hi everyone,

I am currently studying the NDVI evolution from 1985 until 2018 (summer only) in a specific arctic region using surface reflectance (level-2) images from Landsat 5, 7 and 8 and ArcGIS 10.6.

I would like to set up a stretched symbology as I find it better (visual aspect) than a classified one.

I tried many options to obtain a consistent symbology for all the rasters I have but it definitely does not work. I can't have the same settings over time or the result is not relevant. As a desperate option, I have also tried to adjust symbology for each year and the visual aspect seems ok (it shows the evolution).

1. Would you have a suggestion to set a consistent symbology?

2. Would it still be relevant to adjust the symbology over time?

Many thanks in advance for your support,

Mathieu
