Main Article Content
Abstract
Buleleng merupakan salah satu kabupaten di Provinsi Bali yang berpotensi mengalami ancaman peningkatan muka air laut. Kenyataan ini membutuhkan tersedianya peta genangan wilayah pesisir sebagai data dasar untuk mitigasi bencana wilayah pesisir. Salah satu data utama yang dapat digunakan sebagai manifestasi data potensi ancaman yaitu trend muka air laut rata-rata dari data satelit altimetri Envisat. Penyediaan data satelit altimetri dengan kualitas yang lebih baik, perlu dilakukan post-processing.
