Enhancing marine bathymetry using new generation satellite sensors

目前，包括澳大利亚在内的全球72%的海洋缺乏高精度的海洋测深仪，特别是在浅海和近岸沿海地区，这导致了各种航行和海上安全事故。海底船舶勘测既费时又昂贵。卫星测高数据提供了另一种解决办法。该项目将利用新的雷达和激光卫星传感器提供的空间全面和前所未有的数据，改进澳大利亚的海洋测深。我们的目标是开发新数据与其他独立数据源整合的技术，为沿海地形测绘、海洋运输和安全管理提供最精确的海洋测深。

Highly accurate marine bathymetry are currently lacking in 72% of the global ocean including around Australia, particularly in shallow seas and near-shore coastal zones, contributing to various navigation and marine safety accidents. Ship surveys of the seafloor are time-consuming and expensive. Satellite altimetry data provide an alternative solution. This project will improve Australia’s marine bathymetry by using spatially comprehensive and unprecedented data from new radar and laser satellite sensors. We aim to develop techniques for integration of the new data with other independent data sources, producing the most precise marine bathymetry for coastal terrain mapping, marine transport and safety management.
