Analisis Terrain Model Digital untuk Pengembangan Pembangunan Potensi Wisata di Nagari Tikalak

The development of tourism areas based on natural potential requires planning that considers the physical conditions of the area so that development can be carried out safely and sustainably. Nagari Tikalak, Solok Regency, has diverse topographic characteristics so that terrain analysis is needed to support the determination of tourism development zones. This study aims to produce a Digital Terrain Model (DTM) based on UAV aerial photography imagery, testing its level of accuracy using the slope method as the basis for compiling a tourism development zone map. Data processing was carried out using Agisoft Metashape to produce the DTM and ArcMap for spatial analysis. The results of the slope analysis classify areas into suitable, moderately suitable, and unsuitable zones for tourism development, where suitable zones are predominantly on flat to gentle slopes and unsuitable zones are on steep slopes that are potentially prone to landslides. and oriented towards sustainable development in Nagari Tikalak.
