Short summary

This paper presents an integrated workflow that builds on satellite images and 3D seismic surveys, integrated with historical depth soundings, to generate regional high-resolution digital elevation models (DEMs). The workflow was applied to the North West Shelf of Australia and led to the creation of new DEMs, with a resolution of 10 × 10 m in nearshore areas and 30 × 30 m elsewhere over an area of nearly 1 000 000 km². This constitutes a major improvement of the pre-existing 250 × 250 m DEM.
