The Highway Information Visual System Based On WebGIS

The quantity and the quality of high ways represent the development of a country. As this business in our country develops rapidly, people want to know more information about the high way.For the convenience of people outing,we should apply the technology of computer and internet to the system of highway information announcement by unifying and sharing all kinds of graphs,figures and maps.Shandong Highway Limited Company designs the highway information visual system that is based on WebGIS,which is to satisfy the requirements of increasing information about the basic facilities of transportation. It adopts the MapInfo Company's MapXtreme and uses the present advanced Java Applet forming methods, completed following several aspects contents:(i)Realized the function of display the changeable speed limit sign on the Internet which inflects the blocked situation in highway by showing electric map;(ii)Realized the functions of route information inquire and public outing information service based on WebGIS,which provides facilitates for the public;(iii)Realized the function of driving expense list based on WebGIS which caused the highway charge to be transparent and detailed;(iv)Realized the function of mutual-conversation forum,which gives the public a terrace through that people can reflect all kinds of problems about the highway to the manage department;(v)Realized the function of archives issuing system in highway manage department,which establishes the foundation for the no-paper work;(vi)According to conformity the data in charge center,realized the function of inner business data sharing and inner data report inquire.Develops the highway information visual system using the WebGIS technology can enhance the system the operating efficiency,strengthen the massive spatial data and attribute data handling ability. Simultaneously it overcame the malpractice of developing this system based on the traditional pattern.and it will certainly become the mainstream direction of GIS development in future.
