Application of Remote Sensing and Geographical Information System in Mapping Land Cover of Srepok Watershed in Central Highland

Abstract

      Management of natural resources in accordance with river basin is an indispensable trend towards sustainable resource management and use. However, in Vietnam, the resources are managed based on administrative boundaries. Therefore, the information and data are scattered in many places with different quality and not willing to be shared, making them unavailable for scientific research. In the present study, remote sensing combined with GIS was used for building the land cover map to correct the input data with regard to Srepok watershed. The process of analysis and classification for Landsat 8 OLI in Srepok watershed in 2015 yielded reliable results with the Kappa coefficient over 0.69 and overall accuracy of 73.53%. As a result, land cover map was produced in Srepok watershed with seven different classes including evergreen forest, deciduous forest, mixed forest, perennial trees, annual crops and specialized land and water surface.
