Earth Observing System AM1 mission to Earth [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 1998
In 1998, NASA launches EOS-AMI, the first of a series of the Earth Observing System (EOS) satellites. EOS will monitor the evolution of the state of the earth for 18 years, starting with the morning observations of EOS-AM1 (10:30 a.m. equatorial crossing time).

Increases in Night Lights Intensity Reveal Extreme Events: A Case of Study on the Ongoing Conflict in Ukraine [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Analyzing night lights images allows identifying and monitoring affected areas during conflicts, as an overall decrease in brightness indicates abandoned or destroyed buildings, curfews, or power shortages. While detecting decrease in lights intensity is

Learning From Detailed Maps: Joint 2D-3D Semantic Segmentation for Airborne Data with Selective Label Fusion [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Objects for topographic maps are often extracted manually by interpreting and segmenting airborne data, such as 2D images and 3D point clouds. Deep learning (DL) with semantic segmentation can automate this process using existing maps as ground labels ...

Earth Observation, Spatial Data Quality, and Neglected Tropical Diseases [PDF]

open access: yes, 2015
Earth observation (EO) is the use of remote sensing and in situ observations to gather data on the environment. It finds increasing application in the study of environmentally modulated neglected tropical diseases (NTDs).

Review of algorithms estimating export production from satellite derived properties

open access: yesFrontiers in Marine Science, 2023
Whereas the vertical transport of biomass from productive surface waters to the deep ocean (the biological pump) is a critical component of the global carbon cycle, its magnitude and variability is poorly understood.
