so2sat

  • Deskripsi :

So2Sat LCZ42 adalah kumpulan data yang terdiri dari radar apertur sintetik yang didaftarkan bersama dan tambalan gambar optik multispektral yang diakuisisi oleh satelit penginderaan jauh Sentinel-1 dan Sentinel-2, dan label zona iklim lokal (LCZ) yang sesuai. Kumpulan data didistribusikan di 42 kota di berbagai benua dan wilayah budaya di dunia.

Dataset lengkap ( all ) terdiri dari 8 saluran Sentinel-1 dan 10 saluran Sentinel-2. Alternatifnya, seseorang dapat memilih subset rgb , yang hanya berisi pita frekuensi optik Sentinel-2, diskalakan ulang dan dikodekan sebagai JPEG.
