Gis In Research And Application Of Military Intergrated Transport Shortest Path Optimizes

Military integrated transport is a development trend of today's military transport, it is not only the inherent requirements to increase economic benefits of military transportation, but also the demands of the quality of construction and innovation of military transport development. This paper base on the military transport shortest path optimization of integrated transport, using spatial network database constructed by Geographic Information System, combine with object-oriented programming software for the second development, analysis and calculate the most optimal path.Analyzing the basic systems of the comprehensive military transportation network, comparing the advantages and disadvantages of various modes of transport, discussing the transport constitutes pattern of our military, proposes to use MapInfo's layered functions were to manage and apply GIS spatial data management capabilities and object-oriented programming software for the database to operate effectively, to achieve an integrated transportation of military protection and military transport integration.Proposed thought of the shortest path algorithm for the military integrated transport based on generalized transport time. Based on the Sample analysis of the past five years, handling a number of military transport data to find railway, waterway, roads in three different types of transport modes conversion time required, and establish the shortest path optimization model fit for large military transport.Against an assumption that the military integrated transport task, drawing diagrams and databases of military traffic, established the road information extraction in space and space topology, using Delphi language for the secondary development of GIS data, then construct the shortest path search function, the GIS platform implementation shortest path optimization, and integrated transport approach and a comparative analysis of a single mode of transport.
