      Abstract
      One of the advantage to utilizing remote sensing is to map bathymetry that more effective and efficient than the others method. Also bathymetry is included into a dynamic system that vulnerable to changes, so that remote sensing technology is the alternative solution which are quickly and periodically to revise the existing bathymetry maps. This research aim is to map the shallow waters bathymerty of Panggang Island, Seribu Islands using image of Worldview-2 by applying Stumpf algorithm (2003) through the selection of the 3 bands combination, Green/Yellow (G/Y), Green/Red (G/R) and Coastal Blue/NIR2 (CB/N2) and presenting it in three dimensions (3D). Band combination model was chosen as the actual depth converter are G/R model with an accuracy of 73.6% for the shallow waters, G/Y model with an accuracy of 69.1% and 74.2% for lagoon areas. The result showed that the bathymetry map’s accuracy rate reached 67%. Complementary the sounding data with bathymetry from the estimation creates a better 3-D image topography of Panggang Island waters.
       
      Salah satu keunggulan memanfaatkan inderaja adalah untuk pemetaan batimetri yang lebih efektif dan efisien dibanding metode lainnya. B atimetri juga termasuk kedalam suatu sistem dinamis yang rentan akan perubahan, sehingga teknologi inderaja merupakan solusi alternatif yang tepat secara cepat dan berkala untuk merevisi peta batimetri yang ada. Penelitian ini bertujuan untuk memetakan batimetri perairan dangkal Pulau Panggang, Kepulauan Seribu menggunakan citra Worldview-2 dengan mengaplikasikan algoritma Stumpf (2003) melalui pemilihan dari 3 kombinasi kanal, Green/Yellow (G/Y), Green/Red (G/R) dan Coastal Blue/NIR2 (CB/N2) dan menyajikannya dalam 3 dimensi (3D). Model kombinasi kanal yang terpilih sebagai konverter kedalaman aktual diantaranya model G/R dengan akurasi 73,6% untuk perairan dangkal dan G/Y dengan akurasi 69,1% dan 74,2% untuk perairan gobah. Tingkat akurasi peta batimetri hasil estimasi mencapai 67%. Penggabungan data pemeruman dengan batimetri hasil estimasi menciptakan gambaran 3 dimensi top ografi perairan Pulau Panggang yang lebih baik.
