OTB Modules¶
Since OTB 9.0, the toolbox is split in packages that can be installed independently. This table shows the list of modules :
Module Name |

Core and Dependencies¶
These are the two only mandatory modules for OTB.
OTB-Core contains optical image preprocessing applications (Pansharpening, Calibration, Orthorectification, etc.), most useful image manipulation tools (ExtractROI, Superimpose, Mosaic, Concatenate, ..) and various applications to manipulate vector data.
OTB-Dependencies contains the dependencies for the core and optional modules.If you install the Core and decide to use an optional module afterwards, you just need to install this optional module over the current OTB install.
The application list for each package is described in the ::doc::Applications` section
FeaturesExtraction¶
This optional module contains classical filtering applications, such as texture extraction, edge extraction, smoothing, morphological operations. This module relies on external libraries (MuParser / MuParserX) contained in OTB-Dependencies. it can be installed along with the Core package with a simple tar extract command and directly available after sourcing the otbenv.profile
Learning¶
This module contains Machine Learning applications based on classical supervised or unsupervised algorithms (SVM, Random Forest, K-Means, Multi-layer Perceptron Neural Network, etc.). Its applications handle the whole processing chain : sample selection, learning, prediction and finalization of a classification map. It also contains a regression framework.
StereoProcessing¶
This module allows to register stereoscopic images and compute disparity in order to build a 3D model from a couple of satellite images in raw / sensor geometry.
SAR¶
This module contains SAR (Synthetic Aperture Radar) applications and covers all the scope of SAR imagery manipulation : SAR Calibration, Unspeckle with temporal filtering, Interferogram, etc.
Hyperspectral¶
This module contains specific applications to handle hyperspectral images : spectral angle classification, end member number estimation or unmixing.
