Enhanced Vegetation Index in LT?
sharsid94 opened this issue · 1 comments
Hello, I see that EVI is not listed as one of the currently available indices (at the very bottom of this page: https://emapr.github.io/LT-GEE/api.html). When I request EVI in LT, I still get values, though they appear to be much lower than the expected range for forest and possibly missing the initial scaling factor (multiplying bands by 10,000) before the EVI equation.
I would really like to use LandTrendr for EVI time series so any clarification on what values are being produced would be helpful.
Hello,
Just following up on the issue above. I was able to calculate EVI with the individual bands using LandTrendr, and I do suspect that they need to be scaled by 10,000 to get the right values. If possible, I would recommend preventing the current code from calculating unscaled EVI values or correcting the code to give properly calculated EVI values.
