04 Factors of Thematic Content on Sea Surface Temperature

18:49, 11/07/2024

Circular 13/2018/TT-BTNMT was issued by the Ministry of Natural Resources and Environment, stipulating technical regulations for the creation of sea surface temperature maps and sea surface chlorophyll concentration maps at scales of 1:500,000 and 1:1,000,000 using low-resolution optical remote sensing data.

According to Circular 13, the thematic data layer on sea surface temperature must ensure the following content elements:

- Areas with no data.- For sea surface temperature, zoning must have a minimum value range of 0.5°C.- Isothermal lines.- Notes on the values of the isothermal lines.

Additionally, the content element on the sea surface chlorophyll concentration is also detailed in Circular 13:

- Areas with no data.- For sea surface chlorophyll concentration, zoning must have a minimum value range of 0.1mg/m3.- Boundaries of the chlorophyll concentration zones.- Notes on the values of the chlorophyll concentration zones.

Refer to the preparation work at Circular 13/2018/TT-BTNMT effective from November 03, 2018.
