Abstrak:Konversi lahan yang terjadi di wilayah perkotaan menajdikan keberadaan ruang terbuka hijau terancam. Ruang terbuka hijau terdiri dari vegetasi yang dapat dianalisis menggunakan penginderaan jauh. Selain menggunakan penginderaan jauh, penerapan sistem informasi geografis (SIG) juga mengambil peran penting dalam mengelola dan menghasilkan suatu informasi spasial. Dengan integrasi penginderaan jauh dan SIG, setiap jenis penutup lahan dapat diketahui persebarannya secara spasial dan dapat dilakukan analisis hingga dipetakan. Citra satelit SPOT-6 digunakan sebagai data untuk mengekstrak informasi penutup lahan vegetasi dengan memanfaatkan metode klasifikasi berbasis objek atau Object-Based Image Analysis (OBIA). Penelitian ini mengkaji pemanfaatan metode OBIA pada citra satelit SPOT-6 yang merupakan citra resolusi tinggi untuk mengidentifikasi penutup lahan berupa jenis vegetasi dengan karakteristik wilayah Kota Bogor. Akurasi penggunaan metode OBIA pada citra SPOT 6 mampu menghasilkan akurasi sebesar 94% dan nilai Kappa sebesar 91%. Dengan resolusi spasial citra SPOT-6 yang digunakan mencapai 1,5 meter, penggunaan metode OBIA di wilayah Kota Bogor mampu dengan baik menghasilkan klasifikasi penutup lahan vegetasi dengan jenis dan karakteristiknya. OBIA mampu membedakan kelas-kelas penutup lahan dengan karakteristik vegetasi yang berbeda seperti, pohon, semak dan belukar, serta herba dan rumput. Kata kunci: OBIA, penutup lahan, vegetasi, RTH, SPOT-6 Abstract: Land conversion that occurs in urban areas makes the existence of green open spaces threatened. Green open space consists of vegetation that can be analyzed using remote sensing. In addition to using remote sensing, the application of geographic information systems (GIS) also plays an important role in managing and producing spatial information. With the integration of remote sensing and GIS, each type of land cover can be identified spatially and can be analyzed and mapped. SPOT-6 satellite imagery is used as data to extract vegetation land cover information by utilizing the Object-Based Image Analysis (OBIA) classification method. This study examines the use of the OBIA method on SPOT-6 satellite imagery which is a high-resolution image to identify land cover in the form of vegetation types with the characteristics of the Bogor City area. The accuracy of using the OBIA method on SPOT-6 images is able to produce an accuracy of 94% and a Kappa of 91%. With the spatial resolution of the SPOT-6 imagery used reaching 1.5 meters, the use of the OBIA method in the Bogor City area is able to produce a classification of vegetation land cover with its types and characteristics. OBIA is able to distinguish land cover classes with different vegetation characteristics such as trees, shrubs, as well as herbs and grasses. Keywords: OBIA, land cover, vegetation, green open space, SPOT-6
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
