Design And Realization Of Three-Dimensional Geographic Information System For The Ancient Qinshu Roads Based On Skyline

Linear cultural heritage refers to groups of material and intangible cultural heritage in linear or zonal areas with special cultural resources.It is often in the specific purpose of human beings,forming an important link between a series of unconnected towns or villages,constitute a chain of cultural relics state.The Ancient Qinshu Roads is one of the most important cultural routes in China and belongs to a kind of linear cultural heritage.It is a general term for the history of crossing Qinling,Bashan,connecting Guanzhong and Sichuan Basin.Because the linear cultural heritage has the characteristics of large scale,multi-dimension and wide content,it is very difficult to display the linear cultural heritage as a whole,and is very difficult for the cultural relic informationization,the planning and protection.With the rapid development of surveying and mapping information technology,the means of obtaining spatial data are more and more advanced.The three-dimensional GIS integrates the multi-source data into one,can be used in the fields of information cultural relics preservation and so on,with its powerful advantages of three-dimensional expression,spatial management and spatial analysis.It can be applied to cultural relics preservation,cultural relics discovery,cultural relics protection,cultural relics repair,cultural heritage and so on,and is very meaningful.It is also conducive to promoting the high efficiency,refinement,technology of cultural relics protection and management in related fields.In this paper,the multi-source data acquired by aerial photography,tilting photography and terrestrial 3D laser scanning technology are integrated into the database.Based on skyline,the 3D geographic information system of The Ancient Qinshu Roads is designed and developed.The system represent the existing state and its development trend of The Ancient Qinshu Roads in multi-Visual and accurate understanding,and provide assistance for the construction of the scientific and effective cultural heritage protection system.
