2MachuPicchu...Constructed in the late 1400s by the Incan ruler, Pachacuti.The city of Machupicchu was built high in the Andes Mountains outside the modern day city of Cuzco.Machupicchu existed as a place of worship and as a royal retreat for Pachacuti and his guests.Abandoned only decades after its construction, Machupicchu was lost to the undergrowth of the jungle only to be rediscovered in 1911.
3Project objective ...Safeguarding the Historical city by supporting the Master Plan of 2005, that was produced through cooperation between the Centre of the World Patrimony of UNESCO and the National Institute of Natural Resources – INRENA.Develop methodologies to create Special 3D model of heritage sites using Laser Scan and high-resolution optical satellite images by combining the following points:Topographic area for correct modelling by Remote sensing data sources such as DEM (digital elevation model).Building 3D model using Laser Scan technology.Exploring the old INCA way to understand the past city applying special image processing.

10Extracting Shadow line … WORKING WITH LEVEL SLICINGWith this specific analysis, the gradient from dark blue to red colour presents the areas that have a lot of reflectance of sands and less roughness. In the above photo one can see the dark red present the current new Inca way to the historical city with old way.
