| With the economic development and constant improvement of the living standards of people, the tourism industry has become more prosperous. The Multimedia Technology and Geographic Information System (GIS) technology universal application, the city tourism authorities and tourism enterprises started to attach importance to tourism information system development and construction, the National Tourism Administration has held the touch-screen system as a tourist information for cities Excellent Tourism City score an important indicator. Tourism Information System (TIS) that distinguishes it from general information query system, and require a system to effectively manage geospatial graphics, multimedia data attribute data elements and tourism, visitors can quickly and easily among the realization of the two-way searches toward the index. Tourism Information System as the current development of the two main basic platform, there are certain flaws in GIS and multimedia productions. Popular at home and abroad multimedia production software Authorware, Director, and so on, these interactive software flexibility and performance practices, but the lack of effective management of tourism map, spatial query, analysis and statistical functions based on the integration of GIS software, such as MapInfo, Arcview, although a strong spatial data processing and analysis functions, but the lack of voice, video, animation and other media information, multimedia ineffective. They can only help text, graphics and tables to express and transmit the information space, a single approach to a large extent reduce the GIS spatial information processing and transmission of results. Multimedia technology will be used in GIS software or GIS will be part of multimedia functions throughout the system, the development of integrated multimedia model of regional tourism information system (Multimedia Tourism Information System, MTIS) is bound to enhance regional tourism information systems skills. Multimedia technology and the perfect combination of GIS, GIS for the development of open another new field, Multimedia GIS has become a hot issue. Spatial Database (SDB), with Geographic Information System(GIS) and the development and application of the database to develop new technology, geographic information system it is an important component of the other applications is part of the premise and the foundation. Can a Geographic Information System to facilitate timely and accurate data from space to obtain the necessary information, the key lies in the organization and spatial database management. Therefore, the only reasonable spatial database design, to develop a sound and efficient geographical information systems.Traditional GIS is undergoing tremendous changes, has been used initially as a layered approach Geographic Information System software, developed to concern map algebra and space operations for Geo-Information Science stage. With the sudden emergence of personal computing, the focus of GIS and transferred to the PC, providing geographic and spatial services. Spatial Database is the topography, surface features and elements contained by geographical coordinates of the point of names and words, such as tagging organization, and in particular the GIS platform and database platform to complete construction, access and system applications.This article take Liming of Yunnan Lijiang as an example, take ArcGis 9. 1 as the platform, and unifies ERDAS IMAGINE 8. 5, based on the geography spatial databases (Geodatabase) of Liming, and Danxia tourism geological landscape of GIS spatial data analysis, such as the DEM analysis, Three-dimensional analysis and so on.As users of tourism information and data visualization, vividness and richness of the special requirements of this use of existing GIS components MapObjects as a platform through visual development tools VB completed Danxia attractions display system production of Liming. |
