Upaya Peningkatan Kualitas Geometrik Citraupaya Peningkatan Kualitas Geometrik Citra Lapan-Tubsat Pada Aplikasi Surveilen

Abstract

Indonesia has developed and operates the LAPAN-TUBSAT micro satellite since 2007 for supporting the surveillance application to observe the earth surface. LAPAN-TUBSAT satellite carried a video camera as an imaging sensor with 5 m ground resolution and 3.5 km swath. Data from this camera still have a weak geometric. This paper will reviews regarding LAPAN-TUBSAT data processing from video recordings as an effort to increase the geometric quality of the LAPAN-TUBSAT image. The correction model rectification of a simple single photograph is used for geometric correction. While the using of super resolution operator for increasing the video image resolution. The correction model rectification of a simple single photograph is used for geometric correction. While the super resolution operator attempted to efforts to increase the resolution of the video image. The experimental results shows geo-reference image with better geometric quality. The evaluation of LAPAN-TUBSAT performance should be carried out In the near future especially for providing Altitude information (Z). This is related to satellite manoeuvre ability to generate a stereo image with better B/H ratioKeywords:Videography system, LAPAN-TUBSAT Satellite, Geometric image improvement

Pemanfaatan Satelit Lapan-A3 untuk Pemantauan Bencana Alam

“…Satelit ini cukup mirip dengan spesifikasi Landsat sehingga sebagian besar potensinya aplikasi didasarkan pada penelitian menggunakan data Landsat. Dengan ketinggian satelit 510 kilometer dan lebar petak imager sebesar 120 kilometer, secara teori pencitra multispektral LAPAN-A3 akan memiliki resolusi temporal 21 hari (Rokhmana & Tri Judianto, 2012) Tabel 1. Spesifikasi Imager LAPAN-A3 Tahap pertama dalam metodologi ini adalah menentukan garis lintang dan garis bujur daerah bencana.…”
