Abstract: the transportation geotechnical engineering geographic information system is playing the vital role in the national economy and in the Transportation engineering construction. The application of GIS and computer technology in building the transportation geotechnical engineering geographic information system has been the focus as well as frontier of transportation in terms of foreign or domestic in recent years. In this paper, the transportation geotechnical engineering geographic information system using component GIS and computer technology, from the perspectives of design of the system software and hardware, overall structure, application functions and so on; discussed the design and development of the transportation geotechnical engineering geographic information system of Jiangxi province.
