Absolute Accuracy Assessment of Lidar Point Cloud Using Amorphous Objects

open access: yesRemote Sensing, 2022
The accuracy assessment of airborne lidar point cloud typically estimates vertical accuracy by computing RMSEz (root mean square error of the z coordinate) from ground check points (GCPs).

The EPOCH Project: I. Periodic variable stars in the EROS-2 LMC database [PDF]

open access: yes, 2014
The EPOCH (EROS-2 periodic variable star classification using machine learning) project aims to detect periodic variable stars in the EROS-2 light curve database. In this paper, we present the first result of the classification of periodic variable stars

Potential Underestimation of Satellite Fire Radiative Power Retrievals over Gas Flares and Wildland Fires

open access: yesRemote Sensing, 2020
Fire Radiative Power (FRP) is related to fire combustion rates and is used to quantify the atmospheric emissions of greenhouse gases and aerosols. FRP over gas flares and wildfires can be retrieved remotely using satellites that observe in shortwave ...

The Clustering of Extremely Red Objects [PDF]

open access: yes, 2012
We measure the clustering of Extremely Red Objects (EROs) in ~8 deg^2 of the NOAO Deep Wide Field Survey Bo\"otes field in order to establish robust links between ERO z~1.2 and local galaxy z5.0 (28,724 galaxies), (I-K_s)>4.0 (22,451 galaxies) and (I-[3 ...

General External Uncertainty Models of Three-Plane Intersection Point for 3D Absolute Accuracy Assessment of Lidar Point Cloud

open access: yesRemote Sensing, 2019
The traditional practice to assess accuracy in lidar data involves calculating RMSEz (root mean square error of the vertical component). Accuracy assessment of lidar point clouds in full 3D (three dimension) is not routinely performed. The main challenge

Application-Ready Expedited MODIS Data for Operational Land Surface Monitoring of Vegetation Condition

open access: yesRemote Sensing, 2015
Monitoring systems benefit from high temporal frequency image data collected from the Moderate Resolution Imaging Spectroradiometer (MODIS) system. Because of near-daily global coverage, MODIS data are beneficial to applications that require timely ...
