Analysis of puddles in Swamp areas of Banyuasin District using the image Lands at 8 by NDWI method

摘要

Stagnant water and flooding in a region generate the disruption of activities from the area use. The swamp area is one of the areas that is always flooded in which nowadays the development in the swamp area is more massive, so that required road infrastructure to support regional development is available. The road construction planning needs to take attention to the areas of inundation that exist in the swampy areas so that the road can be built by the basic function of the swamp. The use of remote sensing technology is an economic alternative that can be used in the introduction of the puddels. In this study, the classification of puddles will be done using the Landsat 8 image with the Normalized Different Wetness Index (NDWI) method by using the combination on band composite 53.The results shows that the classification by obtaining the range of reflectance value in which (-0.7851) - (-0.404') for non-water body, (-0.4041) -(-0.2021) for low puddles, (-0.2021) - 0.0733 for medium puddles, 0.0733 -0.1057 for high puddles, and 0.1057 - 0.8726 for rivers.
