A comparison of change detection analyses using different band algebras for Baraila wetland with Nasa's multi-temporal landsat dataset.

摘要: Wetlands are those landscapes which saturated with water or covered by either perennially for a major part of the year. Due to transforming nature wetlands from aquatic terrestrial, related physical features not easy be monitored. With recent advancement in Remote sensing technique, feature extraction wetland help different satellite derived band algebras including Normalized Difference Vegetation Index (NDVI), Water (NDWI), Modified NDWI (MNDWI), Moisture (NDMI) is being used experts. The common diagnostic surface water, swamps and vegetation. present study based on comparison between these four indices. Baraila Vaishali district Bihar selected as site because this “BAT” shaped has decreased rapidly last half decade alarming ecology biodiversity.
