IEEE Transactions on Geoscience and Remote Sensing, 2021
Here, four normalized difference water index (NDWI) variants, i.e., NDWI(860,970), NDWI(860,1240), NDWI(860,1640), and NDWI(1240,1640) are generated from the corn-oriented PROSAIL radiative transfer model. It is found that, instead of the linear relationship derived in previous studies, corn canopy water content (CWC) is best approximated as an ...

Mariculture Zones Extraction Using NDWI and NDVI
Advanced Materials Research, 2013On the analysis of spectral characteristics of Aoshan remote sensing images, we find the spectral differences between mariculture zones and other surface features. This paper combines normalized difference water index with mariculture zones distribution planning to complete the extraction and the statistics of the mariculture zones, in order to ...

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.

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 ...
