Professor, how can I create a DEM elevation model file from the surface of the external appearance using the Qgis Orfeo Toolbox plugin? Please answer me, and thank you very much, Doctor.
I just had the same problem but managed to solve it! In the previous steps I had created a new shapefile for the masks/samples, started edit mode, drew the required polygons and went straight on with the next step. I, however, forgot to stop the edit mode and save the newly created polygons. Therefore, the sample file was in fact EMPTY, hence why it didn't work. Now it did.
Hi, I have the same problem and indeed at the beginning I hadn't saved the new layer. However even saving it I still don't get the output files. Any suggestion? Thanks!
Hello I can´t find the OTB plugin in the repository for Qgis There is a solution for it? My Qgis is 2.10.1, 64 bits on Windows 8. I followed the instructions in wiki.orfeo-toolbox.org/index.php/QGIS_access_to_OTB_applications. But I couldn´t find the OTB plugin in the plugin installer Thank you
Hello, you could try the following, which has worked for me: 1) Install the 'Desktop Install' package (64Bit) from trac.osgeo.org/osgeo4w/ 2) Run the installer again, this time selecting Advanced Install. In the search bar when viewing the packages available - type 'OTB' and select 'Install' for all the 'Libs' that come up in the results. 3) Once installed, load up QGIS, go to Processing -> Options -> Providers -> Orfeo Toolbox (Image analysis) and change the 'Value' for 'Applications' and 'Command Line' folders to 'C:\OSGeo4W\apps\orfeotoolbox\applications'. 4) Open up the toolbox with Processing -> Toolbox. 5) Ensure that 'Advanced Interface' is selected.

does this only work with a single satellite image or ortho photo? multiple bands cannot be used?
Beatiful. Using in my master thesis, greetings from Brazil!
can you please tell me, how to create a .qml file for classes?
Hello! When I am doing the TrainImageClassifer (svm), no files (csv ad model) appear when I want to do the ImageClassification. Any idea?

Hi, I had the same problem. I still dont get the output files. Any ideas?
@@bobvandermeij6685 I also did not stop editing, but after stopping, I still have the same problem.
Probably, don't keep spaces in the folder path, and also while saving the file names. I hope that helps!
