Python plugins
|
|
--------------
|
|
Set OTB environment
|
|
--------------------
|
|
|
|
export PYTHONPATH=/path/to/OTB/install/lib/otb/python/:$PYTHONPATH
|
|
# Environment variable for old OTB versions
|
|
export ITK_AUTOLOAD_PATH=/path/to/OTB/install/lib/otb/applications/
|
|
# Environment variable for new OTB versions
|
|
export OTB_APPLICATION_PATH=/path/to/OTB/install/lib/otb/applications/
|
|
# Set LD_LIBRARY_PATH
|
|
export LD_LIBRARY_PATH=/path/to/OTB/install/lib/:$LD_LIBRARY_PATH
|
|
|
|
Set QGIS environment
|
|
---------------------
|
|
export QGIS_PREFIX_PATH=/path/to/QGIS/install
|
|
export PYTHONPATH=:/usr/share/qgis/python/plugins:~/.qgis2/python/plugins:$PYTHONPATH
|
|
# Set LD_LIBRARY_PATH
|
|
export LD_LIBRARY_PATH=$QGIS_PREFIX_PATH/lib/:$LD_LIBRARY_PATH
|
|
# Add maintenance folder to python path
|
|
export PYTHONPATH=/path/to/QGIS/src/python/plugins/processing/algs/otb/maintenance:$PYTHONPATH
|
|
|
|
Check the white and black list for the current OTB version
|
|
----------------------------------------------------------
|
|
In the maintenance directory, the OTB applications are split in two files black_list.xml and white_list.xml.
|
|
These files are organized as follows :
|
|
For each OTB version, a new node version with id as attribute is added to the node data.
|
|
Each application is then added in the node app_name.
|
|
```xml
|
|
<?xml version="1.0"?>
|
|
<data>
|
|
<version id="3.16">
|
|
<app_name>BinaryMorphologicalOperation</app_name>
|
|
<app_name>EdgeExtraction</app_name>
|
|
<app_name>GrayScaleMorphologicalOperation</app_name>
|
|
<app_name>DimensionalityReduction</app_name>
|
|
<app_name>Pansharpening</app_name>
|
|
<app_name>ExtractROI</app_name>
|
|
<app_name>RigidTransformResample</app_name>
|
|
<app_name>Segmentation</app_name>
|
|
<app_name>KMeansClassification</app_name>
|
|
<app_name>TrainSVMImagesClassifier</app_name>
|
|
<app_name>ComputeConfusionMatrix</app_name>
|
|
<app_name>OpticalCalibration</app_name>
|
|
<app_name>SarRadiometricCalibration</app_name>
|
|
<app_name>Smoothing</app_name>
|
|
</version>
|
|
</data>
|
|
```
|
|
The list of available applications for each version is not fixed.
|
|
|
|
OTBSpecific_XMLcreation.py
|
|
--------------------------
|
|
Warning : Some of the applications needs to be split to be user-friendly. Here comes the file OTBSpecific_XMLcreation.py.
|
|
Each function follows the pattern getNameOfTheOTBApplication().
|
|
|
|
Creating xml files
|
|
------------------
|
|
cd /path/to/QGIS/src/python/plugins/processing/algs/otb/maintenance
|
|
python ./OTBHelper.py
