Theme oriented enhancement of sea surface temperature in thermal infrared avhrr images

  • 23 Accesses


The paper provides a brief description of NOAA satellite AVHRR (Advanced Very High Resolution Radiometer) and also the concept of theme oriented enhancements and touches upon the efforts deployed in developing the software module for its realisation under project INTERACT (International Education and Research for Application of Computer Technology). The paper provides the details of one of the eighteen enhancement curves implemented and which refers to the sea surface temperature. The enhanced output image and comparison of the brightness temperature values of the enhanced portion of the image with the sea surface temperature values available from other sources have been discussed.
