The increasing maturity of the current technologic landscape makes the adoption of Trusted Crowd-Sourced Bathymetry (TCSB) finally achievable. Especially for very sensitive areas like the Arctic region, TCSB has the potential to become one of the primary sources of geospatial information both for safety and security of the maritime territory as well as climate adaptation research. 

The installation of a network of  low-cost and reliable bathymetric data loggers aboard designated partners’ vessels is not only already achievable, but national hydrographic offices should pursue it as a concrete answer to the increasing demand of updated and extended nautical information. 

The target of this whitepaper is to combine our efforts for the creation of a modern infrastructure able to handle large amounts of TCSB data. This document outlines a vision—commonly developed by the Canadian Hydrographic Service and the Danish Geodata Agency—for the continuous acquisition and automated processing of TCSB data streams from a network of selected partners (the ‘trusted crowd’) into nautical charts and publications.
