Monitoring of dynamic wetland changes using NDVI and NDWI based landsat imagery
Remote Sensing Applications: Society and Environment, 2021Abstract Recent initiatives using the GIS tools for mapping and analysis of wetland dynamics bring the hope for an effective wetland management. Degraded or modified wetlands are more sensitive and less resilient to the climate change. This paper focusses on a study of water bodies in Sirmaur District, Uttarakhand, India with the special focus on ...

NDWI-DeepLabv3+: High-Precision Extraction of Water Bodies from Remote Sensing Images
2020 The 3rd International Conference on Machine Learning and Machine Intelligence, 2020How to efficiently and accurately extract water bodies from remote sensing images is the focus of scholars' research. Current research often does not make full use of the unique multi-band data of remote sensing images. This paper proposes an improved NDWI-DeepLabv3+ network to improve the accuracy of water body extraction, especially from urban remote

Crop drought monitoring using serial NDVI&NDWI in Northern China
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004Drought is one of the major environmental disasters in north China, and it is very important to detect and monitor drought periodically at large scale for decision making. The Normalized Difference Vegetation Index (NDVI) has been widely used to monitor moisture-related vegetation condition.

Water stress monitoring using NDWI around deserts of China and Mongolia
SPIE Proceedings, 2009The fluctuation of vegetation water condition around desert area is one of most important parameters to interpret the desertification expansion. United Nations reported that about 35 million square kilometers of land are subject to desertification. Historically, many parts of China have been suffered from severe desertification.

Uso da ferramenta ndwi para modelo de análise de disponibilidade de água
Proceedings of..., 2022Environmental problems related to water resources and soil degradation are increasingly frequent, resulting in changes in the hydrological cycle and in the fluvial characteristics of hydrographic basins. The presence of small dams along the hydrographic network can contribute to the guarantee of ecological flow, even in periods of drought. However, the

Mapping and analysis of the flooded areas using NDWI
2019There is a single-channel and multi-channel approach to classification. Access Code that uses multiple channels, NDVI (Normalized Difference Vegetation Index) and "water" index NDWI (Normalized Difference Water Index). NDWI index is similar as the NDVI-ROM, and the function is visible green and close infrared radiation. This formulation index enabled: (

Assessing Transferability of Landsat-derived NDWI Values across Space and Time
2014Normalized Difference Water Index (NDWI) derived from the reflectance values of green and infrared bands is a widely used index for the delineation of water bodies in remotely sensed images. While attempting to identify water bodies in a remotely sensed image the analyst has to determine the threshold for NDWI values that correspond to lakes ...

ABSTRACTClear and green water bodies reflect more green light than red light, while brown water bodies reflect more red light than green light. It is thus believed that the normalized difference water indexes using the green band and infrared wavelengths (NDWIgreen) and the normalized difference water indexes using the red band and infrared wavelengths
