Radiometric cross-calibration of Göktürk-2 with Landsat 8

open access: yes2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Radiometric calibration studies need to be done during the life-time of a satellite. In this paper, reflectance-based cross calibration was conducted at Tuz Golu LandNet site in 2016 using Gokturk-2 and Landsat 8 imageries. Using near-simultaneous images of the satellites under the same atmospheric conditions reduces the effect caused by reflection ...

Applications of Landsat-8 Data: a Survey

open access: yesInternational Journal of Engineering and Technology, 2018
Landsat 8 was launched in 2013 by the National Aeronautics and Space Administration (NASA). On board of the Landsat 8 is the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS). Data for visible, panchromatic band, short-wave infrared spectral bands are collected by the OLI while TIRS collect images in the thermal region.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...
