Integrasi Inderaja dalam Menentukan Batimetri Perairan Sekitar Pulau Kelapan, Kabupaten Bangka Selatan, Provinsi Kepulauan Bangka Belitung

Integration of Remote Sensing in Determining Bathimetryat surroundinging waters Kelapan Island, South Bangka Regency, Bangka Belitung Archipelago Province

Abstract

This research conducted in the Kelapan Island of Pangkalpinang, South Bangka Regency, Bangka Belitung Archipelago Province. Kelapan Island had been overgrown by mangrove cummunity which tendtobevaried and unique. Research related to bathymetry mapping in the Kelapan Island area has never been carried out and minim information, therefore this research needs to be done to find out bathimetryof surrounding waters at the Kelapan Island by using remote sensing technology and GIS.  The research and gound check carried out on November  2016 -  January 2017, assisted by using secondary data from related agencies to test image accuracy. Image Processing and layouting bathymetry map conducted in LAPAN. Bathymetry data analysis uses satellite drivedbathymetry algoritm and linear regression. The image used in this research uses landsat 8 imagery with an image resolution of 30 meter.The result showed that there are interrealated between the depth value with satellite drived bathymetry value from image processing. The best linear regression is y=143.9x-137.4depth value with satellite drived bathymetri value, indicated the value of the coefficient of determination (R2) of 0.764 indicates that the coefficient number is positively related. The result of the layout map made using the ArcMap software show that a depth of 6 – 10 meters with using Satellite Drived Bathimetry(SDB) algorithm (range: 4 -11 m) is differentiated using a color difference for each depth.
