SERTIT uses OTB applications on both Linux and Windows platforms for remote sensing tasks. OTB is handled through Ubuntu, Scientific Linux, and Windows 7 operating systems. Examples of OTB usage at SERTIT include analyzing vegetation along a railway using Pleiades imagery in a collaboration with SNCF, and understanding changes at China's Poyang Lake using a temporal series of 11 Pleiades images to extract water, calculate submersion time, and classify land use into 16 classes.
