Study On Full Information Physical Geographical Environment Of Red Dabie Mountain

Since modern times,red culture can not only stimulate people's patriotic enthusiasm,but also inspire the national spirit,which is of great scientific research value;On the other hand,at this stage,map visualization has gradually been paid attention to and developed.Visualization technology can directly convert unclear historical information into visible map information.However,historical data has some limitations because it can not directly reflect the distribution of red culture in space.GIS technology is used to combine historical data in space and time,study its changes in space-time scale,and then build a real scene three-dimensional scene model through tilt photography technology,which can intuitively browse and display important relic points,and has unique advantages in the full information visualization of red Dabie Mountain.Based on this advantage,it can not only combine the large scene model of Dabie Mountain area with the real scene three-dimensional model to build a twodimensional and three-dimensional integrated real geographic environment visual display platform,but also summarize and design the visual display rules that can express the implied cultural information of the region without affecting the viewing of the real scene of the region.So as to realize the expression and full information display of red culture in real 3D,and solve the problems of poor visualization effect of existing historical data and incomplete display elements.The red culture in Dabie Mountain area can not be ignored in the historical process of Chinese revolution,and is of great significance in Chinese red culture.This thesis selects some revolutionary action tracks in Dabie Mountain Area from 1927 to 1947,the birth process of the 11 main Red Army in Jinzhai County,and some important relics in Jinzhai County as visual research objects,and systematically studies the full information display of red culture in Dabie Mountain area,It has important practical guiding significance for the display and development of red culture in Dabie Mountain Area and even other old revolutionary base areas.The main conclusions are as follows:(1)In this thesis,the two-dimensional and three-dimensional visual design of red culture information are carried out respectively.In terms of two-dimensional visualization,this thesis designs six kinds of point symbols,four kinds of Linear symbols,two kinds of area symbols,one kind of annotation symbols and several auxiliary elements.In terms of three-dimensional visualization,taking the real threedimensional model of the Red Army square as an example,in the full information visualization of the core area,this thesis designs five types of symbolic symbols:Marble relief,digital implication,name title,spatial layout and cultural landmarks.Through the above design,the visual display of red culture resources in Dabie Mountain area is realized,so that the traditional red culture information hidden in the text can be expressed intuitively.(2)In this thesis,through UAV photogrammetry,the real three-dimensional models of 23 red cultural relics selected from Nanxi Town,tangjiahui town and Meishan town in Jinzhai County are constructed and embedded into the large-scale three-dimensional topographic map,and the real geographical environment of the integration of large scene and fine scene in Dabie Mountain area is established.At the same time,a two-dimensional and three-dimensional visual display platform of red Dabie Mountain is designed to realize the organic integration of two-dimensional and three-dimensional red cultural resources information of Dabie Mountain.(3)Taking the three plates of Qianli leap forward Dabie Mountain,Jinzhai Red Army Road and important relic points as examples,this thesis shows the use effect of the real geographic information environment of red Dabie Mountain.In addition,307 questionnaires were used to evaluate the full information visualization effect of red Dabie Mountain.The results show that through the real geographic information environment,the red culture information can be expressed accurately,truly and dynamically.
