Denver-based TCarta Marine uses earth observation satellites to provide accurate water depth measurements for near-shore areas. “The risk of such accidents can be significantly reduced with up-to-date bathymetric data produced from satellite imagery,” TCarta president Kyle Goodrich said in a statement.
