Service Description: Peta Koefisien limpasan ini dihitung menggunakan metode rata-rata berbobot (Weighted Runoff Coefficient) berdasarkan formula Schwab et al. (1981), di mana nilai koefisien tiap kelas tutupan lahan dikalikan dengan luas pikselnya, lalu dijumlahkan dan dibagi dengan total luas wilayah. Data yang digunakan berasal dari citra Sentinel-2 Level-2A yang telah diproses (masking awan, koreksi reflektansi, dan penambahan indeks spektral) untuk periode 1 Januari–22 Oktober 2025, serta data sampel training tutupan lahan yang digunakan untuk membangun model klasifikasi Random Forest. Hasil klasifikasi tersebut kemudian dikonversi menjadi nilai koefisien limpasan (C) untuk menghasilkan peta dan estimasi nilai rata-rata koefisien limpasan wilayah Jawa Barat.
