Vegetation and Built-Up Area Monitoring in Bandung City Using Multitemporal Imagery

Abstract

Bandung is West Java's largest metropolitan city and Indonesia's third largest. The city of Bandung is very strategic in various aspects, such as accessibility, communication, public facilities, and the economy. The Increased population in Bandung indicates more complex ongoing human activities, which can then affect changes in land use. The land covers in urban areas tends to change more drastically over a short period e than in rural areas because of rapid urbanization. Therefore, urban phenomenon changes are ideally monitored and detected from satellite images with a multitemporal resolution. Vegetation greenness and built-up areas can identify through multitemporal remote sensing imagery. Changes in vegetation and built-up area can monitor using remote sensing with multitemporal imagery. The analysis of changes in vegetation and built-up area studied in Bandung City represents an area with rapid population growth. This study aims to: 1) Identify changes in vegetation greenness in Bandung City between 2014 and 2021, 2) Identify built-up area changes in Bandung City between 2014 and 2021, 3) Analyze the relevance between vegetation greenness and the built-up area in Bandung City—the correlation between NDBI and NDVI through selected samples is representative of all data in Landsat 8 imagery. The proportion between the values of NDBI and NDVI samples is 0.9034. So, it is concluded that the two variables are positively correlated. Therefore, the study’s results recommend preserving vegetated land cover to conserve natural resources and prevent increased land surface temperature.Keywords: Remote Sensing Imagery, Built-Up Area, Vegetation Greenness, Bandung City

Analisis Pola Distribusi Spasial Keterkaitan Kepadatan Penduduk Dan Kerapatan Bangunan Melalui Google Earth Engine Menggunakan Metode Normalized Difference Built-Up Index

“…Hasil akurasi penelitian yang di lakukan adalah sebesar 91,4505% akurasi yang melebihi 80% itu menunjukan akurasi yang sangat tinggi [9]. Berdasarkan penelitian yang di lakukan oleh Tulung et.al, NDBI adalah transformasi yang efektif untuk memetakan kawasan terbangun perkotaan secara otomatis [10]. Hasil dari pengolahan NDBI yang digunakan untuk penelitian mendapatkan hasil yang sangat positif.…”
