A Study Of Expression On Red Ribbon Of The Earth In GIS Pattern

Geographic Information System(GIS)is in the process of socialization and publicity.All the theoretical research of GIS aims to solve social problems and to provide public services.Although the publicity of GIS is the only way of discipline development,the visualization characteristics of GIS also play a catalytic role.The publicity of GIS is based on the public resources of society,which makes the publicity develop faster.GIS has been involved in the field of history and literature,such as a Tang Dynasty poet,Li Bai's poetry track and spatial analysis,and the spatial analysis of the birthplace and death place of thinkers and masters of literature and art in the Renaissance.The content of these cases are to describe the life of the relevant characters,the core of which is visualization and spatial analysis.The documentary novel Red Ribbon of the Earth shows the magnificent picture of the Chinese Red Army fighting against the enemy in all directions and the harsh environment in the Long March.Based on this book,this paper extracts text information by the relevant processing methods of unstructured data in spatial-temporal narrative,developing WebGIS with the latest front-end modular development technology,establishing a public oriented Long March story map system based on GIS,and realizing the geographic language expression and immersive expression of documentary novels.This paper mainly completed the following work:(1)This paper organizes the data in four dimensions of space,time,character and event,with concluding the novel,sorting out its content and organizing the data with the method easy to express through GIS.This paper establishes a geographic database including three types of geographical elements:point,line and area,as well as a non spatial database including attribute table of characters,attribute table of events of the Red Army,attribute table of sub events of the Red Army,attribute table of events of encirclement and suppression of the Kuomintang army,attribute table of process of encirclement and suppression of the Kuomintang army.(2)According to the characteristics of data organization,the query function based on spatial elements,character information,time information and event information is designed and implemented,and the visualization effect of data is realized,which includes character layer,event layer,hotspot data layer and base map layer.Based on the three elements of geography,the dynamic simulation function of key events and the corresponding spatial operation function are realized.The contents of this book were used to develop GIS.The visual contents displayed in this book not only to make readers feel that GIS technology gives people an intuitive and three-dimensional feeling,but also to make them feel the shock and inspiration of Red Culture.
