ANALISA METODE EKSTRAKSI BANGUNAN DENGAN MENGGUNAKAN SEGMENTASI OBYEK DAN PROBABILITAS HOUGH TRANSFORM STUDI KASUS KECAMATAN RUNGKUT KOTA SURABAYA

ABSTRAK

Kota Surabaya yang aktivitas kotanya sangat bervariasi dengan jumlah penduduk lebih dari tiga juta Hasyim Hariyanto dkk. 2011. Kegiatan pembangunan fisik dan prasarana perkotaan di Surabaya tentunya menimbulkan konsekuensi terhadap perubahan obyek bangunan. Dengan terjadinya perubahan obyek bangunan maka perlu adanya sebuah studi dengan metode yang sesuai untuk mengekstraksi informasi bangunan. Penelitian ini menggunakan metode ekstraksi bangunan pada Citra Satelit Resolusi Tinggi WorldView-2 dengan menggunakan segmentasi citra berbasis obyek dan Probabilitas Hough Transform. Kemudian didapatkan hasil ekstraksi bangunan dari proses segmentasi berbasis obyek yang hasilnya diolah dengan metode Hough Transform. Hasil kedua metode ekstraksi bangunan di atas dianalisa dengan data lapngan untuk mengetahui ketelitian dari metode tersebut. Analisa kedua yaitu dengan membandingkan antara hasil ekstraksi obyek bangunan pada segmentasi dan Hough Transform dengan Peta Garis Objek Bangunan. Didapatkan nilai presentase kemiripan Hough Transform lebih bagus daripada Segmentasi obyek. Terdapat 15 poligon dari 28 poligon yang menunjukkan nilai kesesuaian Hough Transform lebih besar. Selain itu juga dilakukan analisa kualitas permukiman dari hasil ekstraksi bangunan yang paling sesuai. Hal ini dilakukan menganalisa beberapa faktor yaitu Kepadatan Bangunan dengan klasifikasi baik kepadatan rumah rata-rata 40 Pola Tata Letak Permukiman dengan klasifikasi buruk nilai tata letak bangunan 25 bangunan yang ada pada permukiman yang tertata teratur dan lebar jalan masuk permukiman dengan klasifikasi baik ketentuan lebar jalan masuk rata-rata 6 meter.


ABSTRACT

Surabaya City is a city which has very diverse activities with a population of more than three million inhabitans Hashim Hariyanto et al. 2011. Physical activities and urban infrastructure in Surabaya certainly have consequences on building object changes . With the change building objects hence the need for a study of the appropriate method for extracting building information. This study uses a method of building extraction in High Resolution Satellite Imagery WorldView-2 using object-based image segmentation and Probability Hough Transform. Then the results obtained from the extraction of building object-based segmentation are processed by Hough Transform method. The results of the two methods of extraction were analyzed by ground thruth data to determine the thoroughness of the method. The second analysis is by comparing between the extracted object segmentation and building on Hough Transform with Object Outline Map Building. Percentage similarity values of Hough Transform more precise than the object segmentation. There are 15 polygons of 28 polygons that show the best similarity value of Hough Transform. It also analyzed the quality of the extraction building settlements most appropriate. This analysis is done based on the condition of the building and the quality of the neighborhoods in the District Rungkut Surabaya. There are four factors building density settlement pattern of neighborhoods and the driveway width.
