On one hand, archaeologists are seeking for details as much as possible but on the other hand most GIS system cannot handle such massive data with millions of meshes. Therefore the usages of mesh models should be divided: one is “visualization” and the other is “information”. When talking about visualization, details should be kept as much as possible. But in GIS, simple models with object attributes are more important. Therefore a connection between simple models and mesh models can be built. For example in GIS system users have clicked on a simple model and a mesh model will be shown on special visualization tools. Further studies can be web applications or UI-based applications which can connect simple GIS models and complicated detailed models. Model simplification and different LOD can be considered in the GIS model reconstruction process. The GIS system or programs may have difficulties in visualizing or storing mesh models today. However, with the development of computer hardware and new algorithms, these data can be used directly in the future
