The Application of Multi Temporal Satellite Data For Land Cover Mapping of Bawean Island, East Java

Abstract

Land cover dynamics in a small island can be determined using Geographic Information System (GIS) approach based on multitemporal image analysis. This study aimed to classify major land cover types and to map land cover changes of Bawean Island. Two sets of 10 meter resolution satellite data ALOS AVNIR (2010) and Sentinel-2A (2020) were used in this study. Satellite image analysis was carried out through several stages namely image pre-processing including radiometric and geometric correction, supervised image classification and accuracy test. Image classification results from 2010 to 2020 showed a significant change in land cover on Bawean Island. The forest vegetation land cover declined significantly from 13,470.5 Ha in 2010 to 8,543.4 Ha in 2020. Most of the area have been converted into paddy fields and built-up areas. The accuracy test and validation were determined by comparing the 2020 Sentinel image classification results with field observation conducted in 2021. The analysis showed good results with 82.52% overall accuracy and 79.66 Kappa coefficient. Further investigation found that changes in land cover on Bawean Island occured due to the agriculture and infrastucture development.

Sustainable Modern Environment Responses on Bawean Architecture

“…Geographically, by mixing different such as Javanese, Madurese, Malay, Buginese, and many other cultures (Setiawan and Amar, 2021), the Bawean built environment is met through temporary meaning to translate the traditional--formal meaning into a newer form (Hidayah et al, 2022).…”
