Spatiotemporal Analysis of Urban Land Cover: Case Study - Pekanbaru City, Indonesia

Abstract

: The number of people has an increasing pattern by years and it will impact spatial aspects. One of the impacts was land cover changes from the non-built area into the built-up area. Pekanbaru is one of developing city in Indonesia that has a high number of the population surge. The purpose of this paper was to analyse the land cover change in the urban area of Pekanbaru city. The analysis spatiotemporal has been done by using Landsat Imagery year of 2000, 2005, 2009 and 2014. The method of this paper was digital classification using maximum likelihood and their integration with Geographical Information Systems (GIS). Land cover classification divided into two classes such as built-up area and non-built up land area. Based on the results, the built-up land area has been increased by years, on the other hand, the non-built up area has declined. The percentage of built-up area change from 29,51% into 59,99%. The spatial distribution of and cover change dominantly occurs in south part of Pekanbaru city. The mean of accuracy index for the land cover map in this research was 85,17%. The land cover change of Pekanbaru city has a decreasing pattern where the year of 2000-2005 has a significant number and decreasing by years massively.
