Abstract

ABSTRAK Kebutuhan akan adanya pengembangan metode untuk meningkatkan akurasi dari interpretasi objek memerlukan kajian metodologi yang disebut analisis citra berbasis objek. Penelitian ini ditujukan untuk menentukan dan menganalisis akurasi dari interpretasi objek secara otomatis dengan metode berbasis objek dengan memberikan bobot yang berbeda untuk setiap kanal. Data yang digunakan adalah foto hasil pemotretan udara format menengah (medium format) dengan resolusi 16 cm. Ekstrak data menggunakan teknik object based image analysis (OBIA). Data diproses berdasarkan bobot yang yang berbeda untuk setiap kanal. Nilai akurasi ditentukan berdasarkan overall accuracy. Overall accuracy merupakan hasil validasi klasifikasi objek dengan ground truth yang diperoleh dari peta garis skala 1:5000 yang diinterpretasi secara visual. Hasil penelitian menunjukkan terjadi peningkatan nilai akurasi dengan pendekatan OBIA jika setiap kanal diberikan bobot yang berbeda dibandingkan dengan bobot yang sama. Peningkatan akurasi paling tinggi dengan bobot (Red=3, Green=4, Blue=3, IR=4, dan DEM= 3) menghasilkan akurasi 85,88%. Hasil akurasi meningkat sebesar 10,27 % dibandingkan dengan interpretasi tanpa pembobotan. Kata kunci: Interpretasi, Peta 1:5000, Klasifikasi, OBIA, Pembobotan, AkurasiABSTRACT Interpretation of imagery or aerial photo is an attempt to understand or interpret imagery to obtain accurate information and in accordance with the recorded object. The need for developing methods to improve the accuracy of the object interpretation requires assessment methodology which is called as object based image analysis. This study aimed at determining and analyzing the accuracy of the interpretation of the object automatically using object based method by giving different weights to each band. The data used were medium format aerial photos with a resolution of 16 cm. The method of data processing was object based image analysis (OBIA). Data were processed by different weights for each band. Accuracy value is determined based on the overall accuracy. Overall accuracy is the result of the validated object classification with ground truth obtained from the map of 1:5000 which were interpreted visually. The research results showed that the value of the accuracy with OBIA approach increased if each band is given different weights compared with the same weight. The highest accuracy was achieved with weights (Red=3, Green=4, Blue=3 , IR=4, and DEM=3), and resulted overall accuracy 85,88%. Results accuracy increased 10,27% compared with the interpretation without weighting. Keywords: Interpretation, Map 1:5000, Classification, OBIA, Weighting, Accuracy
