The objective of this research is to propose a utilize tactics of remote sensing data for coastal marine environment monitoring. Statement of principles for using Sea Surface Temperature (SST), which is based on feasibility study for utilizing remote sensing data, focuses on regular monitoring from Moderate Resolution Imaging Spectroradiometer (MODIS) data and gathering of timely information from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data. To develop a procedure for estimating SST from ASTER data is necessary to combine “Quality of ASTER data” and “Algorithm for estimating SST from ASTER data”. In this research, “5 bands method using recalibration L1B data” has showed the best procedure for estimating SST from ASTER data. Furthermore, Specialists of administration section have reviewed practical scenario of utilization of SST. As a result, SST from remote sensing data is effective tool to monitor the coastal marine environment, if observation frequency and quick delivery of satellite information satisfy with user's needs.
