Automated Subpixel Surface Water Mapping from Heterogeneous Urban Environments Using Landsat 8 OLI Imagery
TL;DR: The results indicate that the proposed AsWM was able to detect water pixels more efficiency than other unsupervised water extraction methods, and the water fractions estimated by the proposed ASWM method correspond closely to the reference fractions with the slopes of 0.97, 1.04, and 0.98.

A survey of methods incorporating spatial information in image classification and spectral unmixing
TL;DR: A comprehensive review of the state-of-the-art techniques in incorporating spatial information in image classification and spectral unmixing and a perspective on future research directions for advancing spatial-spectral methods is offered.
Inter-annual Water Storage Changes in the Aral Sea from Multi-mission Satellite Altimetry, Remote Sensing, and GRACE Satellite Gravimetry
TL;DR: In this paper, the authors used a combination of radar and laser satellite altimetry data sets over the Aral Sea to estimate the water level of the lake and its surrounding.

Monitoring surface water area variations of reservoirs using daily MODIS images by exploring sub-pixel information
TL;DR: In this article, the authors proposed a new approach that aims to monitor reservoir surface water area variations accurately and timely from daily MODIS images by exploring sub-pixel scale information, which makes it possible to directly estimate the whole reservoir water area from, potentially, an individual cloud-free MODIS pixel.

Analysis of Dynamic Thresholds for the Normalized Difference Water Index
Lei Ji,Li Zhang,Bruce K. Wylie +2 more
TL;DR: In this article, the normalized difference water index (NDWI) has been successfully used to delineate surface water features, but two major problems have often encountered: (a) NDWIs calculated from different band combinations [visible, nearinfrared, or shortwave-infrared (SWIR)] can generate different results, and (b) NDWI thresholds vary depending on the proportions of subpixel water/non-water components.
