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.

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.

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: (
