[otb-users] Windows : install OTB with Python

[swiky aquilla]

Hi all,


I am trying installing the otbApplication on Python but it is not working…I 
want to use the \otbcli_LargeScaleMeanShift.bat
file. 
I follow all the discussion on this subject on otb-users group, without 
success.

I have downloaded OTB-6.4.0-Win64.zip (binary package) here : 
https://www.orfeo-toolbox.org/download/ 


I Added 6 paths on the environment variables (System Properties > 
Environment Variables > System variables), on PATH : (see the attached file)
C:\Users\asi\Downloads\OTB-6.4.0-Win64\bin
C:\Users\asi\Downloads\OTB-6.4.0-Win64\lib\python3
C:\Users\asi\Downloads\OTB-6.4.0-Win64\lib\otb\applications
C:\Users\asi\Downloads\OTB-6.4.0-Win64
C:\Users\asi\Downloads\OTB-6.4.0-Win64\bin\otbcli_LargeScaleMeanShift.bat


I change the PYTHONPATH of the otbenv file 
(C:\Users\asi\Downloads\OTB-6.4.0-Win64\otbenv.bat) 
set CURRENT_SCRIPT_DIR=%~dp0
set PATH=%CURRENT_SCRIPT_DIR%bin;%PATH%
set GDAL_DATA=%CURRENT_SCRIPT_DIR%share\data
set GEOTIFF_CSV=%CURRENT_SCRIPT_DIR%share\epsg_csv
set PYTHONPATH=%CURRENT_SCRIPT_DIR%lib\python3;%PYTHONPATH%
set OTB_APPLICATION_PATH=%CURRENT_SCRIPT_DIR%lib\otb\applications
set GDAL_DRIVER_PATH=disable
:: Set numeric locale to C
set LC_NUMERIC=C


I work on jupyter Notebook, with Anaconda (version : conda 4.5.4), and 
Python 3.6.5.
When I enter : 
import otbApplication
the error is :
ModuleNotFoundError   Traceback (most recent call last)
 in ()
> 1 import otbApplication

ModuleNotFoundError: No module named 'otbApplication'


I Don't know what to do to fix it.

Can someone help me or have an idea ?

Thank you very much in advance !!

Yes, you can create it by hand with any text editor, provided that you comply 
with the format (which I believe is x y lat lon h).

I wouldn't use the homologouspointsextraction application. Is there a way to

RE: [otb-users] Re: KMeansClassification error with nodata value

[Michel Julien]

Hi,

-vm parameter should do the trick (only non-zero values will be used to 
estimate the k-means). You can build the mask with the ManageNoData 
application. If this does not work, I encourage you to open an issue in gitlab.

Hello

I have tiled Pleiades images (panchromatic and multispectral ) and tried to do 
pasharpening.
Firstly I have generated the mosaic image (merging the tiles), then used the 
Superimpose (setting the multi-spectral image to have the same extend and 
resolution as the panchromatic one), and then Pansharpening. But it doesn't 
work...it generates only for the upper part of the image...

I tried to do it for a single tile and it worked fine...but how can I use these 
approach on the mosaic?

Thank you

RE: [otb-users] getting started

[Michel Julien]

Hi,

I think that you should not move the package. If you want to use OTB from 
jupyter, it is possible, you just need to launch it after running the otbenv.sh 
script to setup the proper environment variables, as explained here :

https://www.orfeo-toolbox.org/CookBook/Installation.html

Hello,

I'd like to use the vertex component analysis capabilities in this package.

It is unclear to me how to to use this package in a python environment like 
Jupyter Notebook or Spyder.

I downloaded the package and moved it to where my other packages are and am 
able to import the package by typing 'import OTB as otb." 'otb.Modules' does 
not work either.

However, I am not sure how to access any functionality of the package. I have 
tried following the instructions 
here
 but "Registry" is no longer a directory in the package.

Any guidance would be helpful.

Thanks,
Jessica

Craig,
Did you ever get this figured out? I am also interested in optical calibration 
of WV03 images. Also, the calibration factor and effective bandwidth are 
embedded into each of the .imd files that come with the imagery from Digital 
Globe. I don't know if these are ever updated in any way, but it seems like a 
good idea to pull them directly from the .IMD file for each image when it is 
imported.

e.g. (Coastal band: absCalFactor = 6.679371e -02; effectiveBandwidth = 
4.05e -02...etc.)

 However, I do not think it is in the correct format. I believe what is 
expected is for the first column to be wavelengths in microns (not nanometers), 
the second column should be solar irradiance (not provided in the file), and 
the next columns are the spectral responses for each band.  I think I can use 
the Thuillier 2003 spectral response curve listed here: 
https://dg-cms-uploads-production.s3.amazonaws.com/uploads/document/file/207/Radiometric_Use_of_WorldView-3_v2.pdf,
 but I'm not sure what order the bands should be listed. The provided file has 
PAN, C, B, G, Y, R, RE, N1, N2, S1, S2, S3, S4, S5, S6, S7, S8. I think since I 
have just the 8-band VNIR product that I should have them in  C, B, G, Y, R, 
RE, N1, N2 order with the others excluded from the file, but I'm not sure.  
Also, what units should the spectral response values be in?  The provided file 
has them as radiance values.

Thanks,

Craig

RE: [otb-users] Worldview-2 .TIL files and OTB

[Michel Julien]

Here is something you can try :

Use otbcli_ReadImageInfo on one of the individual geotiff files (preferabily 
the upper left one, should be named R1C1 no ?) to write down a geom file 
containing the metadata. Then attach the geom file to the TIL file with 
extended filename : -in “mytil.TIL?=theGeomFile.geom”.

Also open a bug report because looking up the correct file from the TIL file 
instead of individual geotiff files should not be hard …

Objet : [otb-users] Worldview-2 .TIL files and OTB

I have a large number of tiled Digital Globe Worldview-2 images that I would 
like to perform optical calibration on. As delivered from Digital Globe, each 
image strip is a folder that contains a .TIL file that arranges the individual 
geotiff files and aligns them into a single image. GDAL seems to handle these 
well, and they import fine (I am currently using Monteverdi for this). However, 
each of these folders also contains an .imd and .xml file. These files each 
contain much of the pertinent information for sensor bias, image date, sun 
angle, azimuth, etc. As far as I can tell OTB does not recognize or attempt to 
use these files. Has anyone attempted to perform these corrections with the 
tiled files from Digital Globe? Thanks,
