How to get Orfeo PatchesExtraction working in qgis 3.8 with orfeo 6.6.1

Hello all,

I am quite new to Orfeo.

I am trying to use Orfeo to extract patches from a raster file in Qgis. The locations of the extraction points are in a shp file. I read Orfeo Has a process called PatchesExtraction which does exactly what in need. I installed the plugin from this tutorial . Sadly, after installing Orfeo I could not find the PatchesExtraction process. Has the name been changed or has it been removed? The reason I want to use this plug in is to create a data set for Google vision AI deep learning.

If any one has any Idea how to get this task done please let me know.

Kind regards,

According to the Patchesextraction tool is in a new remote module for OTB called OTBTF. I have found the module on github but haven’t the slightest idea of how to use it.

Hi Thomas,
In order to use applications provided in otbtf you must compile otb+otbtf from sources.
You can find build instructions in the readme.
There is also a dockerfile that builds everything for you (you must have docker installed, there is plenty of tutorials online how to build/use a docker image)

Hope that will help you :slight_smile:
