Analysis of Land Use Changed in Ponorogo Based on Landsat 8 Imaginary using NDVI Classification

Abstract

Land use is a form of human intervention inland to meet the needs of both material needs and spiritual needs. Land use analysis is important for agricultural planning, urbanization and environmental studies. Remote-sensing data and GIS are an appropriate tool for the assessment of the global land-use change and environmental monitoring because of its spatial and temporal coverage capabilities. The change detection and assessment of land use using geospatial information allow the user to monitor land user over the large area and over a period of time. This study aims to classify land use in Ponorogo using Landsat 8 imagery. The normalized difference vegetation index (NDVI) is used for the mapping of changes in the land cover. In this study the NDVI based classification has indicated about significant change in land use between year 2015 and 2017. The major change has been found in areas with dense vegetation such as forest, farm, where about 4.22% of areas have been degraded between year 2015 and 2017.
