I implemented the following script but it return “Layer NDVI-VALUE Not Found”. Is there something wrong with the code? Or does it mean there are no NDVI values available over this time period?

http://services.sentinel-hub.com/ogc/fis/20d4447c-MASKED?LAYER=NDVI-VALUE&STYLE=INDEX&CRS=EPSG%3A3857&TIME=2020-10-01%2F2020-11-05&BBOX=1550369.86,5586056.25,1547498.69,5584861.92&RESOLUTION=10&MAXCC=10

Dear @ed6543,

it looks to me as if you didn’t use a correct {INSTANCE_ID} in your request (the 20d4447c-MASKED par). You get the {INSTANCE_ID} from the dashboard in the configuration utility.

For the request to work correctly you need to have a layer set up in the instance you use which returns the NDVI and which has the exact ID specified in your request NDVI-VALUE. Judging from the error message you got this layer does not exist.

I tried the request with the steps in mind described above (on S2L1C - data) and got results so there is data available for your period. I hope that helps!

If you didn’t already see our documentation on FIS requests it might also be worth checking them out here.


Hi Ed,
as Daniel mentioned, the problem is that in your configuration ( [20d4447c-MASKED) there is NDVI-VALUE layer missing.
Go to Configuration utility, enter this configuration and add it.

Dear @dthiex ,

Thanks for your quick response. I inserted MASKED in the INSTANCE_ID on purpose but I did use a complete INSTANCE_ID.

You also wrote: “I tried the request with the steps in mind described above (on S2L1C - data) and got results so there is data available for your period.”

Can you please share exactly what you requested, and the results, so I can compare against my request?

What I am trying to achieve is extract the NDVI value only from a particular time period at a certain location.

Thanks,
Ed
