SPARSO map reveals 900 sqkm shoal along coast

There are 900 square kilometres of tidal shoal along the Bangladeshi coast at present, a Bangladesh Space Research and Remote Sensing Organization (SPARSO) map has identified.

SPARSO has made the map using Landsat-8 images and centnel-2 satellite images, it was disclosed in a seminar organised by SPARSO at its office in Dhaka on Tuesday.

Chief scientific officer of SPARSO Md Mahmudur Rahman presented the keynote in the seminar, while the organisation’s chairman Md Zafar Ullah Khan presided over the program.   

“Bangladeshi coast is changing. New shoals have become visible due to silt arriving from the upstream through different rivers. For this reason, new maps are needed on a regular basis,” said Md Mahmudur Rahman.

Shoal is a sandbank or sand bar in the bed of a body of water, especially one that is exposed above the surface of the water at low tide.
