OTB is a community driven, extensible and heavily documented open-source project for remote sensing. It can process high resolution optical, multispectral and radar images at the terabyte scale. All of algorithms are accessible from QGIS, Python, the command line or C++. It’s available on Linux, Windows, and macOS (via Docker for ARM Mac computers). Features include:

• Features extraction
• Change detection
• Image manipulation
• Image Segmentation
• Hyperspectral processing
• Data pre-processing
• Data pre-processing
• SAR processing

Supported formats:

• Image formats supported by GDAL (tiff, hrd, img, data providers specifics …)
• Vector formats supported by GDAL/OGR (shapefile, sqlite, postgis …)
• Metadata formats supported by OSSIM and OSSIM plugins (Pléiades and other ADS sensors, DigitalGlobe sensors, NITF)
• Digital Elevation Models supported by OSSIM (SRTM, DTED and generic geotiff DEM)
• KMZ image export
