Land mapping with least median of squares regression using landsat imagery: A case study Jakarta and surrounding area

Abstract

Impervious surface is an area that has undergone natural or semi-natural substitution of artificial land cover which is usually waterproof and relatively permanent, including settlements, industrial buildings, road networks, railroad networks, high voltage electricity networks, airports air and sea ports. Changes cause the narrowing of rivers and open land which become water catchment areas. One of the problems that triggered an increase in impervious land is urbanization. This study aims to map land changes in the Jakarta and surrounding areas using the least median of squares regression method. Based on data from land classification results using 4 classes, Jakarta and Tangerang are areas that have more impervious land than non-impervious land. Meanwhile, Bogor, Bekasi, and Depok are areas that have more non-impervious land.
