TCarta has delivered satellite derived bathymetry (SDB) to Total SA, one of the world’s largest oil and gas producers. Total will use the water depth data for preparing seismic survey works off the coast of Myanmar. TCarta generated the SDB dataset by digitally extracting accurate water depth measurements from multispectral imagery acquired by the European Space Agency’s Sentinel-2 satellite.The resulting bathymetric data had a point spacing of 10 meters with measurements to a depth of 15 meters. The deliverable covered a 30-square-kilometer area around Preparis Island in the Bay of Bengal. “Our processing team delivered the satellite derived bathymetry just a few weeks after Total placed the order,” said TCarta CEO David Critchley. “Traditional airborne or shipborne bathymetric mapping would have taken several months and cost ten times more.” www.tcarta.com
