Airborne Photon‐Counting LiDAR for Shallow‐Water Bathymetry With Robust Noise Removal and Depth Retrieval

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Airborne photon‐counting LiDAR has emerged as a promising tool for shallow‐water bathymetry, offering high spatial resolution and penetration depth for coastal and nearshore applications. This study presents an integrated workflow for processing airborne photon‐counting LiDAR data to estimate shallow‐water bathymetry.

Ends of strata of the moduli space of quadratic differentials

, 2012
Very few results are known about the topology of the strata of the moduli space of quadratic differentials. In this paper, we prove that any connected component of such strata has only one topological end.

A case study of geoid modeling in Sulawesi and accuracy verification strategies for accommodating diverse MSL vertical datums

Terrestrial, Atmospheric and Oceanic Sciences
This study aims to introduce the geoid modeling process in Sulawesi and demonstrate the practical issues faced. There are limitations of terrestrial gravity surveys in Sulawesi due to its complex geography, so airborne gravity surveys were conducted from

Evaluating the Potential of Sea Surface Height Observations and Depth Datum Calculation Using GNSS/IMU Buoys

Journal of Marine Science and Engineering
This study evaluates the potential of GNSS/IMU buoys for sea surface height observations and depth datum verification. GNSS/IMU buoys were deployed alongside 34 tide gauges around Taiwan for synchronous sea surface height measurements. The collected GNSS

Numerical investigations of non-uniqueness for the Navier-Stokes initial value problem in borderline spaces

, 2017
We consider the Cauchy problem for the incompressible Navier-Stokes equations in $\mathbb{R}^3$ for a one-parameter family of explicit scale-invariant axi-symmetric initial data, which is smooth away from the origin and invariant under the reflection ...

ESTUDOS DO NMM A PARTIR DE SÉRIES TEMPORAIS MAREGRÁFICAS E DE ALTIMETRIA POR SATÉLITES VISANDO A INTEGRAÇÃO DA REDE VERTICAL BRASILEIRA AO SIRGAS

Revista Brasileira de Cartografia, 2009
Na Geodésia, o monitoramento do nível do mar tem um papel importante na realização de sistemas globais de referência e permite a integração de dados referidos às redes verticais clássicas, onde cada Datum é definido pelo Nível Médio do Mar (NMM), com ...
