Assessing the suitability of lakes and reservoirs for recreation using Landsat 8. [PDF]

Environ Monit Assess, 2023
Abstract Water clarity has long been used as a visual indicator of the condition of water quality. The clarity of waters is generally valued for esthetic and recreational purposes. Water clarity is often assessed using a Secchi disk attached to a measured line and lowered to a depth where it can be no longer seen.

Landsat 8 OLI Broadband Albedo Validation in Antarctica and Greenland [PDF]

Remote Sensing, 2021
The albedo is a fundamental component of the processes that govern the energy budget, and particularly important in the context of climate change. However, a satellite-based high-resolution (30 m) albedo product which can be used in the polar regions up to 82.5° latitude during the summer seasons is lacking.

ACIX-Aqua: A global assessment of atmospheric correction methods for Landsat-8 and Sentinel-2 over lakes, rivers, and coastal waters

Remote Sensing of Environment, 2021
Atmospheric correction over inland and coastal waters is one of the major remaining challenges in aquatic remote sensing, often hindering the quantitative retrieval of biogeochemical variables and analysis of their spatial and temporal variability within

Deep Learning Semantic Segmentation for Land Use and Land Cover Types Using Landsat 8 Imagery

ISPRS Int. J. Geo Inf., 2023
Using deep learning semantic segmentation for land use extraction is the most challenging problem in medium spatial resolution imagery. This is because of the deep convolution layer and multiple levels of deep steps of the baseline network, which can ...

Evaluation of Landsat 8-like Land Surface Temperature by Fusing Landsat 8 and MODIS Land Surface Temperature Product [PDF]

Processes, 2021
High-spatiotemporal-resolution land surface temperature (LST) is a crucial parameter in various environmental monitoring. However, due to the limitation of sensor trade-off between the spatial and temporal resolutions, such data are still unavailable. Therefore, the generation and verification of such data are of great value.

The Spectral Response of the Landsat-8 Operational Land Imager [PDF]

Remote Sensing, 2014
Abstract: This paper discusses the pre-launch spectral characterization of the Operational Land Imager (OLI) at the component, assembly and instrument levels and relates results of those measurements to artifacts observed in the on-orbit imagery. It concludes that the types of artifacts observed and their magnitudes are consistent with the results of ...

A Study of the Land Cover of Razzaza Lake during the Past 25 Years Using Remote Sensing Methods

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023
In this study, the Earth's surface was studied in  Razzaza Lake for 25 years, using remote sensing methods. Images of the satellites Landsat 5 (TM) and 8 (OLI) were used to study and determine the components of the land cover. The study covered the years
