Segmentation on SNAP

[ELHACHIMI]

Hello everybody

I want to do a segmentation for a sentinel-2 image on SNAP.

I’m working with SNAP 5.0.

Hope you can help me.

Thanks!

segmentation can be done in SNAP using the external OTB adapters - please see here:

Beta OTB Adapters available

A Beta version of Orfeo Toolbox SNAP Adapters is available for tests. These adapters allow to launch from SNAP some of the main OTB tools (4 Segmentation tools, 3 Pan-Sharpening tools, SFS Texture Extraction and Multivariate Alteration Detector) To install them is first required to set-up a new update center. From SNAP, go to tools/plugins then click on the Settings tab and press the "Add" Button to add a new update center. Put the name of your choice and http://step.esa.int/updatecenter/exp…

Put the name of your choice and http://step.esa.int/updatecenter/experimental/otb/updates.xml.gz in the URL field. The OTB Adapter will appear in “Available plugins”. Select the module and press the “Install” button to install them.

Hi ABraun ,

Yes all is well, the plugin is correctly installed

But I cant find the plugin in the SNAP tools.

[ABraun]

you are right. Mine are gone as well. It used to work with SNAP 4.x but there may be incompatibilities with SNAP 5.0

You can ask for an update in the other topic.

[ELHACHIMI]

OK thanks a lot ABraum.

a temporary solution has been suggested but didn’t work for me by now.

External Tools disappear when restarting SNAP - workaround

It has been identified a problem with the tool adapters in the new version of SNAP (5.0). This bug is not allowing to SNAP loading the tool adapters of Sen2Cor and OTB when restarting. This will be fixed soon with a module update (probably the next week). Meanwhile, there is a workaround: if you create an empty folder called 'java' in the SNAP installation folder the external tools will be loaded properly. Depending on the toolboxes selected during the installation, the snap installation folder …

Have you tried to reinstall the OTB Adaptor after creating the ‘java’ folder? I think then it should work.

[ABraun]

yes, also restarted several times. But I’ll try again.

[marpet]

Probably it is better to remove the java entry in the snap.clusters file which is located in the etc folder.

[ABraun]

thank you for the suggestion. Although the installation of the plugin seems to be fine, I can’t find it anymore under SNAP 5.0. Tested on 2 computers.

But for me it’s no problem to wait for the update.

Hello everybody,

I have the same problem as ARraum.

Is this problem will be resolved with the new version of SNAP ???

[ABraun]

According to the original post, yes.

Happily I am still working with SNAP 4 but I get following errors when I try to initialise the segmentation:

Any ideas? Looks like some kind of environment variable related issue…

Cheers

You need to go to Tools/Manage External Tools and select the OTB adapter there and click Edit. In the dialog which will open you can configure the variables.
