Apply Index operator

Hello,

 

 

In the Spatial Workshop, the MSI (Moisture Stress Index) doesn't work on Sentinel-2 20m bands (It works in Imagine).

Re: Apply Index operator

Hello Remi,

 

By "doesn't work" do you mean completely black output or you are getting some error?

Re: Apply Index operator

Hello Marina,

 

 

The script doesn't end (please find the attached log file). On the contrary it works with ndvi705 entry. With Sentinel-2 20 bands images, it should work with both ndvi705 and msi indexes.

 

Regards,

Re: Apply Index operator

Hello Remi,

 

I am not sure if that is a problem of Apply Index operator. In error log you've send I see that Classification was run (classifyisodata.exe).

 

Here are my steps while testing:

 

I've opened in IMAGINE Sentinel-2 SAFE file and picked to display only 20-m layers. Generated a subset of some smaller territory to .img.

Than uploaded data to M.App Chest.

 

I was able to run the following simple model successfuly:

2017-01-13 12_52_02-Spatial Workshop.png

 

 

Could you please share with me your model? Or here, or in pravite message.

 

 

Thank you.

 

Kind Regards,

Marina

Re: Apply Index operator

Thanks Marina,

 

 

I would like to test my data first because there is no problem when running the model within Imagine.

Re: Apply Index operator

Hello Marina,

 

The problem seems to come from the uploaded data to the MapChest or linked to the size of it, moment I don't know. I've a little subset of the sentinel Image, pass it through the script in the MapStudio and obtain result.
