Hi Monika,
if I understand the tutorial I think that the XML is created using the
*ComputeOGRLayersFeaturesStatistics* application.
You can find the documentation of it in the otb cookbook:
https://www.orfeo-toolbox.org/CookBook/CookBooksu125.html#x157-9360004.9.1

Manuel

Hello OTB Team,
Sorry for a stupid question, I am really new with this software, and
using OTB toolbox in QGIS.
I am trying to do automatic segments classification, following

<http://wiki.awf.forst.uni-goettingen.de/wiki/index.php/Object-based_classification_%28Tutorial%29>
<https://lh3.googleusercontent.com/-5n-Pz2GG2KY/V1WeqNPmIGI/AAAAAAAABAw/hvPIXjkVB64ggi2AHvcB7JDJ6MTKjX8PgCLcB/s1600/askkkkobia.png>
I managed to create the training shapefile (first red arrow). However,
the next step is requiring "XML file containing mean and variance of
each feature", but I cannot find the shapefile. I tried to create the
xml. signature file using SCP classification module, but it is not
working.
My questions are:
1. When created vector file using "Join Attributes by Location", is a
companion .xml file automatically created?
2. If not, how to created that "XML file containing mean and variance
of each feature"?
Thank you, hope you can help.
