Digital and automated photogrammetric procedures, developed for the collection and management of spatial data, and terrestrial laser scanning systems provide new capabilities for documentation of archaeological monuments and sites. Also, special tools in Spatial Information Systems and production of virtual models have been developed. Their combination provides relevant scientists (architects, archaeologists, etc) and users with a variety of options for the creation of integrated systems capable for documentation, restoration and cultural development of archaeological sites. Detailed 2D and 3D representation of the current condition of the site, development of a multi-purpose SIS, and introduction of modern digital products at a local museum, such as 3D models, creation of virtual environment and Web applications are some of them. Application of such techniques and systems was made to the archaeological site of the Mycenae in Greece, one of the most important sites worldwide.
