Research Of Road GIS Based On ArcGIS Engine

Rural road is an important infrastructure for the construction of new social country, having significant influence on the followings: the country economical development, the adjustment of agriculture industrial structure and the safety and convenient traffic for the people traveling. Although the country road has remarkable function in the whole social economical development, the traditional road management can't make it day after day, Geographic Information System provides a set of tools for the highway Information management with its powerful visualization, spatial database management and spatial analysis functions .It's necessary to develop rural road Information management system based on GIS.The related theory of the GIS technology is researched deeply in this issue, This paper builds Hunan rural road Geographic Information System according to the actual requirement and the data characters of the country road. The system frame and function module are designed based on the detailed analysis of system users and system functions. The road geometrical information database is built based on such technologies as. space data hierarchical technology, geometry data model of space data base and data management technology of object-relation. And realized the spatial-temporal management and sharing of multi-level geo-spatial data in a better way, the system was built with the integrated secondary development of ArcGIS Engine elements base invoked by .net language, accomplishing the functions as following: huge capacity data management, map browsing and editing, road information management, layer management, space analyzing, and data output and so on. The security of the road data is considered fully and various of modern techniques are used for the data security management in the development of the system.This system has applied well in Hunan province, it makes a greatly changing in rural road information management model, and providing a good platform of analyzing, managing and decision-making for the rural road construction of Hunan province, having some practical significance and innovative.
