Crowdsourced bathymetry (CSB) is the collection of depth measurements from vessels, using standard navigation instruments engaged in routine operations.

International Hydrographic Organisation (IHO) accepts CSB data into the Data Centre for Digital Bathymetry (DCDB) through a network of ‘Trusted Nodes’.

The ‘Crowdsourced bathymetry on the GBR‘ project is a Trusted Node. The talk will focus on how CSB data are collected, processed and made public.
