Potential of 3d laser point cloud data usage for the tourism industry.

Abstract
Laser scanning technology, both mobile and terrestrial, has encountered great technological advance during past few years. It gives us the opportunity to acquire great amounts of precisely measured data. 3d laser scanner technology is used in the development of tourism industry in some tourist places in Egypt, where this technology plays major roles in various fields that contribute to the industry of tourism, archaeology and preservation of ancient heritage. The point cloud plays major roles various fields that contribute to the tourism industry such as archeological exploration, heritage, monument preservation and 3d information technology. A much more suitable acquisition platform is 3d laser scanner where point cloud is collected with very high accuracy and details. The level of details is an essential requirement for tourism applications. National Research Institute of Astronomy and Geophysics NRIAG added Vehicle mobile laser scanner and terrestrial laser scanner systems to its Crustal Movements Laboratory–Geodynamic Department to investigate the potential of 3d laser scanners in various fields and disciplines such as the tourism industry and archaeological preservation. The main objective of this work is to cover several basic points, the elevation of the archaeological areas with high accuracy. Make photographic videos of archaeological sites. 3d modeling (virtual reality) is used for archaeological buildings and cemeteries and digitizing them with a very high accuracy especially as they are based on real data that helps in documenting them for future generations and preserving their historical value and restoration.
