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

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.

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

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: (

Analisa Perubahan Garis Pantai Di Kabupaten Indramayu Menggunakan NDWI
Jurnal Perikanan UnramKabupaten Indramayu merupakan salah satu daerah di pesisir utara Pulau Jawa dengan panjang garis pantai ±140 km. Selama 15 tahun terakhir telah terjadi fenomena abrasi dan akresi di Kabupaten Indramayu, sehingga menyebabkan perubahan besar pada garis pantai. Oleh karena itu, perlu memanfaatkan teknologi penginderaan jauh untuk melakukan penelitian guna

Why NDWI threshold varies in delineating water body from multitemporal images?
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Water body can be extracted from a satellite image with normalized difference water index (NDWI). It is commonly known that the index varies if extracting water body using multi-temporal images. This study selected 33 cloud-free scenes of MODerate-resolution Imaging Spectroradiometer (MODIS) data over the Poyang Lake region located in a subtropical ...
