ISPRS International Journal of Geo-Information, 2022 The Full Waveform LiDAR system has been developed and used commercially all over the world. It acts to record the complete time of a laser pulse and has a high-resolution sampling interval compared to the traditional multiple-echo LiDAR, which only ...

Full waveform inversion using triangular waveform adapted meshes
CoRR, 2021 In this article, continuous Galerkin finite elements are applied to perform full waveform inversion (FWI) for seismic velocity model building. A time-domain FWI approach is detailed that uses meshes composed of variably sized triangular elements to discretize the domain.

FULL WAVEFORM ACTIVE HYPERSPECTRAL LIDAR [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 We have developed a prototype full waveform hyperspectral LiDAR and investigated its potential for remote sensing applications. Traditionally hyperspectral remote sensing is based on passive measurement of sunlit targets.

Multiscale full waveform inversion [PDF]
Geophysical Journal International, 2013 We develop and apply a full waveform inversion method that incorporates seismic data on a wide range of spatio-temporal scales, thereby constraining the details of both crustal and uppermantle structure. This is intended to further our understanding of crust-mantle interactions that shape the nature of plate tectonics, and to be a step towards improved

Randomized Source Sketching for Full Waveform Inversion [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2022 Partial differential equation (PDE) constrained optimization problems such as seismic full waveform inversion (FWI) frequently arise in the geoscience and related fields. For such problems, many observations are usually gathered by multiple sources, which form the right-hand-sides of the PDE constraint.

USING FULL WAVEFORM DATA IN URBAN AREAS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 In this paper, the use of waveform data in urban areas is studied. Full waveform is generally used in non-urban areas, where it can provide better vertical structure description of vegetation compared to discrete return systems.
