PENERAPAN METODE PENGINDERAAN JAUH DAN SISTEM INFORMASI GEOGRAFIS UNTUK ANALISA PERUBAHAN PENGGUNAAN LAHAN (Studi Kasus: Kawasan Danau Maninjau)

Abstract

Studies of changes in land use is very important, because changes in land use have an impact on the physical and social environment. The purpose of this study was to determine the use and change of spatial land in the area of Lake Maninjau by using satellite images and research in the field.
