Exporting Min/Max/Mean from Vegetation Indices Time Series

First some general comments related to your configuration and request:

• 
  

  When using L2A data source, you should not also use atmospheric correction (ATMFILTER=FULL). ATMFILTER option. See
  https://www.sentinel-hub.com/faq/what-kind-atmospheric-correction-available
  
  and
  https://www.sentinel-hub.com/faq/what-difference-between-atmospheric-correction-filter-and-l2a-data-source

  
  


• 
  

  Note that L2A data are available in Europe since March 2017 in Europe and December 2018 globally.

  
  


• 
  

  the layer you are using for FIS is configured as visualization layer, which means that you are getting values of red/green/blue bands rather than vegetation index.
  

  
  
  

Looking at the results of the request, results only available since December 2018, I feel that your coordinates are wrong, that you are looking at area outside Europe. So probably lat and lon are switched?

By changing the order I get results from 2017 as one would have expected:
http://services.sentinel-hub.com/ogc/fis/e814485d-2d6f-MASKED?LAYER=VEGETATION_INDEX&CRS=CRS%3A84&TIME=2015-01-01%2F2019-2-25&BBOX=13.522797,48.985135,13.524106,48.984322&RESOLUTION=10&MAXCC=5&ATMFILTER=NONE

(Note that I masked the instance ID os that others cannot abuse it)

In order to get actual values rather than visualisation, I suggest you check this post:

How can I get actual NDVI values?

How can I get actual NDVI values? You will have to use 32-bit float image type (as uint8 and uint16 types only support integers).

and

How can I create EO products?

How can I create EO products? Follow the steps described here.

I created a new layer called NDVI-INDEX in your instance, so that you can try:
http://services.sentinel-hub.com/ogc/fis/e814485d-2d6f-MASKED?LAYER=NDVI-INDEX&CRS=CRS%3A84&TIME=2015-01-01%2F2019-2-25&BBOX=13.522797,48.985135,13.524106,48.984322&RESOLUTION=10&MAXCC=5&ATMFILTER=NONE

I hope this helps?

Hi, Thank you for your reply, anyway, there is still mistake, look at the values of Vegetation Index and also on mix/max/st. deviation. This is not corresponding with the values in EO Browser (and you can not get st. dev. all zeros). I have tried your URL here:

And this is what I get from the EO for the same area (there is different mean/min/max values). And also, if you select 0 % clouds in EO and in URL (MAXCC=0), you get different number of scenes.

Hi, sorry, my mistake, the values of mean are corresponding. But If I use URL, for all values (MIN=MAX=MEAN) I get only NDVI mean from the area Please, can you prepare for me the same layer for Moisture Index (not values for visualization of the layer, but the values of the Moisture Index) as you prepared for NDVI in my Configuration Utility? Thanks a lot!

The reason, why MIN and MAX are the same as MEAN is probably due to the fact that your area is extremely small, e.g. only one pixel.

For moisture index do follow instructions available here:
https://www.sentinel-hub.com/faq/how-create-eo-product

You will find script for Moisture index here:
github.com

sentinel-hub/custom-scripts/blob/master/sentinel-2/moisture_index/scripts.js

if (B8A == 0 || B11 == 0){

  return [0,0,0];

} else {

  var val = (B8A - B11)/(B8A + B11);

  

  var vmin = -0.8;

  var vmax = 0.8;

  var dv = vmax - vmin;

  

  var r = 0.0;

  var g = 0.0;

  var b = 0.0;



  

  var v = val;



  if (v < vmin){

    v = vmin;

  }

  if (v > vmax){

the first four lines are actual calculation of the index, the rest is for visualization.

So in your case the script would be:

if (B8A == 0 || B11 == 0){

return [0];

} else {

var val = (B8A - B11)/(B8A + B11);

return [val];

Hi, Thank you very much!!!

Hello. Please help me. MIN, MAX in graphic values the NDVI?
