Perbandingan Ketelitian Metode NDVI Melalui Software Global Mapper Dan Arcgis

Abstract

Normal Difference Vegetation Index (NDVI) merupakan algoritma untuk mendeteksi indeks vegetasi dari citra satelit. Pengolahan indeks vegetasi pada penelitian ini menggunakan algoritma NDVI dengan memanfaatkan kanal/band 5 (NIR) dan 4 (RED) pada Landsat 9 OLI 2 perekaman tanggal 26 Oktober 2024 Hasil pada penelitian ini menunjukkan terjadi perbedaan hasil analisis pada masing-masing kelas pada software Global Mapper dan ArcGIS. Luas Kelas Klassifikasi Kerapatan Vegetasi pada Software Global Mapper menunjukkan bahwa luas tertinggi pada kelas Non Vegetasi seluas 16696,2 Ha atau 46,82% diikuti Kelas Tingkat Kehijauan Tinggi seluas 5755,9 Ha atau 16,14% dan luas yang terendah pada kelas Kehijauan Sangat Rendah seluas 3245,7 Ha atau 9,1%. Sedangkan pada Software ArcGIS hasil yang diperoleh, luas Kelas klasifikasi tertinggi pada Kehijauan Rendah Seluas 9396,4 Ha atau 26,35% dan diikuti kelas Non Vegetasi seluas 9206,7 Ha atau 25,82%. Luas terendah ditempati kelas Kehijauan Tinggi seluas 3821,3 Ha atau 10,72%. Hasil uji ketelitian, menunjukkan bahwa menggunakan Software ArcGIS terdapat 8 area yang sesuai dengan kondisi eksisting atau sekitar 80% kesesuaian dari area sampel sedangkan dengan menggunakan software Global Mapper menunjukkan area yang sesuai dengan kondisi eksisting hanya 2 area atau 20% dari area sample. Kata Kunci: NDVI, ArcGIS, Global Mapper
