Virtual Reality in Village Folk Custom Tourism

Some famous tourist cities of China, such as Xi’an, establish the tourism resources information system in natural landscape, human landscape, heritage, and achieve a modern tourist information services and management through the advanced network geographic information technology. Although there are a lot of development examples of tourism information system, they have various deficiencies. Using of information technology has penetrated into modern tourism industry. It brings new business revolution for rapid development of tourism. However, present tourism system is out of keeping with development requirement of village folk custom tourism industry. Application of virtual reality technology in tourism not only can play a part in drumbeating, influence and attractiveness, but can also meet the tours and aesthetic demands of those people who haven't or not be capable of getting there in a certain level. We can combine with virtual reality and real reality to make system more unfeigned. At the same time, 3D visualization and virtual reality makes up for insufficient of space scenes expression in WebGIS. It can make geospatial data realistically exhibit in real space, dynamically and figuratively depict objective phenomenon of landscape, and provide new technology for decision maker in reasonable planning of scenic spot. Therefore we integrated WebGIS, Network, spatial information, 3D modeling, 3D roaming and multimedia technology to establish the “Village Folk Custom Tourism Service System”. It can use virtual reality technology to make virtual reconstruction and 3D simulation for typical folk custom information.


Introduction
With the prosperous development of socialist construction in China, the tourism is increasingly becoming new growth point of economy and one of the main pillars of the tertiary industry.It becomes hotpot in current international tourism industry because of rich national cultural connotation and strange exotic ambiance.Some famous tourist cities of China, such as Xi'an, establish the tourism resources information system in natural landscape, human landscape, heritage, and achieve a modern tourist information services and management through the advanced network geographic information technology.Although there are a lot of development examples of tourism information system, they have various deficiencies.Using of information technology has penetrated into modern tourism industry.It brings new business revolution for rapid development of tourism.However, present tourism system is out of keeping with development requirement of village folk custom tourism industry.Application of virtual reality technology in tourism not only can play a part in drumbeating, influence and attractiveness, but can also meet the tours and aesthetic demands of those people who haven't or not be capable of getting there in a certain level.We can combine with virtual reality and real reality to make system more unfeigned.At the same time, 3D visualization and virtual reality makes up for insufficient of space scenes expression in WebGIS.It can make geospatial data realistically exhibit in real space, dynamically and figuratively depict objective phenomenon of landscape, and provide new technology for decision maker in reasonable planning of scenic spot.Therefore we integrated WebGIS, Network, spatial information, 3D modeling, 3D roaming and multimedia technology to establish the "Village Folk Custom Tourism Service System".It can use virtual reality technology to make virtual reconstruction and 3D simulation for typical folk custom information.
This system is based on spatial information technology and multimedia virtual reality technology.It can display famous scenic site, local customs and practices, entertainment and tourist transportation, deeply mine local characteristics of village, build external propaganda window, establish visualization and publishing platform, achieve systemic organization and efficient management, promote culture exchange and protect excellent traditional folk custom tourism resource.
