Façade structure reconstruction using spaceborne TomoSAR point clouds [PDF]

, 2012
Very high resolution SAR tomography using multiple data stacks from different viewing angles enables us for the first time to generate 4D point clouds of the illuminated area from space with a point density comparable to LiDAR.

Intercomparison of Water Vapor Data Measured with Lidar during IHOP_2002. Part II: Airborne-to-Airborne Systems [PDF]

, 2007
The dataset of the International H2O Project (IHOP_2002) gives the first opportunity for direct intercomparisons of airborne water vapor lidar systems and allows very important conclusions to be drawn for future field campaigns.

Assessment of terrain elevation estimates from ICESat-2 and GEDI spaceborne LiDAR missions across different land cover and forest types

Science of Remote Sensing, 2022
Accurate measurements of terrain elevation are crucial for many ecological applications. In this study, we sought to assess new global three-dimensional Earth observation data acquired by the spaceborne Light Detection and Ranging (LiDAR) missions Ice ...

Regional Scale Rain-Forest Height Mapping Using Regression-Kriging of Spaceborne and Airborne LiDAR Data: Application on French Guiana

Remote Sensing, 2016
LiDAR data has been successfully used to estimate forest parameters such as canopy heights and biomass. Major limitation of LiDAR systems (airborne and spaceborne) arises from their limited spatial coverage.

Model-based inference for biomass estimation in a LiDAR sample survey in Hedmark County, Norway [PDF]

, 2011
In forest inventories, regression models are often applied to predict quantities such as biomass at the level of sampling units. In this paper, we propose a model-based inference framework for combining sampling and model errors in the variance ...

Design and evaluation of multispectral LiDAR for the recovery of arboreal parameters [PDF]

, 2014
Multispectral light detection and ranging (LiDAR) has the potential to recover structural and physiological data from arboreal samples and, by extension, from forest canopies when deployed on aerial or space platforms.

Performance Evaluation of Spaceborne Integrated Path Differential Absorption Lidar for Carbon Dioxide Detection at 1572 nm

Remote Sensing, 2020
As one of the most influential greenhouse gases, carbon dioxide (CO2) has a profound impact on the global climate. The spaceborne integrated path differential absorption (IPDA) lidar will be a great sensor to obtain the columnar concentration of CO2 with

Performance evaluation of spaceborne oceanographic lidar for optical properties detection in global ocean [PDF]

EPJ Web of Conferences
Detection of vertical distribution of optical properties in global ocean is of high priority to the study of marine environment and carbon cycle. Lidar has the advantage of measuring profiles of optical properties in the water. In this paper, in order to
