Emerging techniques in Digital Terrain Analysis (DTA) leverage advances in geoinformatics, high-resolution remote sensing, and computational modeling to enhance the understanding of Earth's surface. LiDAR (Light Detection and Ranging) has become a crucial tool, providing precise three-dimensional elevation data that enables detailed terrain mapping, slope analysis, and micro-topography detection. Integration of UAV (Unmanned Aerial Vehicle) imagery with photogrammetry allows rapid generation of high-resolution digital elevation models (DEMs), particularly useful in inaccessible or hazardous regions. Machine learning and AI algorithms are increasingly applied to
