Information content of weak lensing power spectrum and bispectrum: including the non-Gaussian error covariance matrix

open access: yes, 2012
We address the amount of information in the non-Gaussian regime of weak lensing surveys by modelling all relevant covariances of the power spectra and bispectra, using 1000 ray-tracing simulation realizations for a Lambda-CDM model and an analytical halo

EFEKTIVITAS DAN PERBANDINGAN PENGUKURAN BIDANG TANAH MENGGUNAKAN METODE RTK-NTRIP DENGAN METODE RTK-RADIO

open access: yesDatum: Journal of Geodesy and Geomatics, 2022
Kegiatan pengukuran dan pemetaan bidang tanah dapat dilakukan dengan menggunakan GNSS metode RTK (Real Time Kinematic) baik RTK-Radio maupun RTK-NTRIP. Pada metode RTK-NTRIP terdapat dua jenis yaituRTK- NTRIP Single Base dan Network RTK. Kedua metode tersebut dibedakan berdasarkan jumlah titik ikat CORS yang digunakan sehingga menyebabkan terjadinya ...

A Multisensor Remote Sensing Approach to Archaeological Prospection: Integrating UAV and Google Earth Data in the Bayan Gol Valley, Mongolia

open access: yesArchaeological Prospection, Volume 33, Issue 1, Page 109-130, January/March 2026.
ABSTRACT This study investigates the effectiveness of drone‐based remote sensing and Google Earth satellite imagery for archaeological prospection in the Bayan Gol Valley, Central Mongolia. Utilizing a fixed‐wing unmanned aerial vehicle (UAV) equipped with RGB and multispectral sensors, we surveyed 655 ha to document Mongol‐period settlement structures

Thermal drone observations capture fine‐scale population decline of short‐tailed shearwaters

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 773-789, December 2025.
Researchers used thermal drone technology to monitor short‐tailed shearwater colonies in Tasmania from 2019 to 2024, discovering a concerning 27% decline in chick numbers during this period. The study estimates that the global population of these seabirds has dropped dramatically by 41% since 1985, falling from 23 million to approximately 13.5 million ...
