Abstract


Armed Police Force Combat Command System is an important part of the information construction of the Armed Police Force . In this paper, based on the armed police operational command system GIS_GPS the three key technologies , the main research contents : Armed Police label: on MapX control of APF plotted . Armed Police label different method is divided into three categories: point-like military standard , linear military standard and pictographs , and design appropriate production methods : point-like the military standard TrueTypeFont method to achieve ; the linear military standard vector the segment plotted ; the hieroglyph using bitmap $ method . GPS and map matching : the GPS data coordinate transformation and projection methods , improved nearly map-matching algorithm , based on the location of the map meshing Optional GPS data and electronic maps prepared match . The best path Search: the shortest path search algorithm , two improvements: a binary heap priority queue as running the data structure , adjacency list as a road network topology storage data structure . Dijkstra algorithm with dynamic programming theory combining the best path search strategy, based on the specific characteristics of the road network , by limiting the search direction at the same time to reduce the size of the search algorithm to improve the operating efficiency of the algorithm .
