Microwave Remote Sensing in Hydrology

NPTEL and Indian Institute of Technology Bombay via Swayam


This course shall explain the fundamentals of microwave remote sensing in passive and active domain with application in civil engineering (hydrology, meteorology). An emphasis is made to teach microwave image processing through open source programming languages like python. Further objective of this course is to make a student capable to interpreting and deciphering the microwave data for complex scientific and policy problems in the water arena, all of which require high quality training.INTENDED AUDIENCE:Researchers, UG and PG students of Engineering, Remote Sensing, Industries working in Microwave remote sensing, environment and climate domain, Academicians working in Water resources and hydrology. PREREQUISITES:NilINDUSTRY SUPPORT:RMSI, ERDAS and similarly all firms/companies which have a remote sensing and GIS applications wing shall recognize/value this course
