ABSTRACT
Sentinel 2 is a satellite launched by a collaboration between The European Commission and the European Space Agency in the Global Monitoring for Environment and Security program. The satellite has a mission to scan the Earth surface simultaneously at an angle of 180 each satellite with a 5 day temporal resolution wilh the same appearance on the equator and has a spatial resolution of 10m, 20m, and 60m. There are multispectral channels including VNIR and SWlR. Four cnannels with 10 m spatia! resolution adapt with SPOT4 or 5 and user comply requirements for land cover classfication. Six channels with 10 m spatial resolution becomes a requirement for other Level 2 processing parameters. Channels with 60m spatial resolution are specified for atmospheric correction and cloud filtering. Based on these specifications, Sentinel 2 can be an alternative for users to obtain image data with spatial, temporal, radiometric, and spectral resolution is better than SPO and Landsat. Sentinental 2 can be downloaded for free nd easy by the general public. The existence of image by Sentinel 2 is expected to be used optimally, especially for remote sensing analysis in marine field. |
