1. Spatial Resolution: Topographic sand tables typically have low spatial resolution, failing to display detailed information such as buildings and roads within a site. This can affect the assessment and decision-making regarding specific facilities within the site.
2. Scope of Application: Topographic sand tables are primarily suitable for the planning and development of large sites and urban areas. Their applicability may be limited for small sites or specific areas.
3. Limitations in Production Technology: The production technology of topographic sand tables may be limited by factors such as materials, processes, and precision, making it impossible to fully reproduce the details of actual terrain.
