1. Intuitive Display: Topographic sand tables visually represent actual terrain and landforms, helping people better understand the geographical location and environmental conditions of a site.
2. Visual Analysis: By adjusting the terrain and building layout in the sand table model, the advantages and disadvantages of different options can be evaluated, providing decision-makers with intuitive and reliable data support.
3. Cost-Effectiveness: Compared to other Geographic Information System (GIS) software, the cost of creating topographic sand tables is relatively low, making them suitable for small to medium-sized projects.
