Topographic Position Indeks Analisys untuk Interpretasi Landform Pulau Lombok Berdasarkan Digital Elevation Model (DEM)

نویسندگان

چکیده

Penelitian ini dirancang untuk dapat memberikan interpretasi landform dengan melakukan penilaian berdasarkan indek posisi topografi ( Topographic Position Indeks ) data DEM, slope serta elevasi tujuan mengetahui nilai posisis suatu wilayah khususnya di Pulau Lombok menginterpretasikan profil memperhatikan sisi visibilitas yang menjelaskan struktur dan kondisi objek. Analisis digunakan dalam penelitian adalah indeks sistem klasifikasi menggunakan metode quintile classification. Sedangkan pemodelan analisis TPI Model Builder . Berdasarkan hasil perhitungan TPI, diketahui memiliki positif standar deviasi mencapai 56,9 mean berada pada -0,73. Hal menunjukkan bahwa visisbilitas kenampakan beragam masuk kategori daerah didominasi oleh berupa plains, /lereng ridges Hasil topografinya sepuluh satuan antara lain: -47,5 Canyons, deeply incised streams ), -20 Midslope drainages, shallow valleys -10,8 Upland headwaters -6,19 U-shape -1,61 Plains 2,98 Open slopes 12,2 Upper slopes, mesas local 30,5 Ridges/hills in 71,8 ridges, small hills plains >71,8 Mt tops, high ).

From Digital Elevation Model to Topographic Information System

The term "Topographic Information System (TIS)" is defined in the first section as one of three categories of spatial information systems. In the second section, a new solution is outlined for the mathematical surface modelling of a digital elevation model (DEM), as a component of a TIS. In the third section, additional data (digital orthophotos, geo-coded satellite images, scanned topographic ...
