Research on symbol fusion in the process of situation visualization

Along to the durative increase of the battlefield situation information, the graphically visualize of which becomes a more and more complicated problem. How to plot the operational symbols on the basic geographical map suitably, clearly and completely deserves more consideration. This article bases on the presentation of huge battlefield information, make a specific research on fusing the operational symbols automatically in different echelon, different task, and different scale, which includes the deployment, aggregation, splitting and the transformation from point symbol to line or area, analyses the basic concepts of symbol fusion and the main problems when using symbols to present the situation.
