Cross-country routeway analysis is an extremely important technique in the military action, and it mainly researches how the terrain of battlefield has influence on maneuver, and chooses the optimal path. At present the research on this respect also quite are few in our army, this paper takes it as the main research content. Especially the author put forward a model of Non-uniform B-spline interpolation model and multi-factor routeway analysis model and choose grid structure to overlap the terrain information and other influence factors, then translated it into a graph theory problem to solve, the paper built the following models:(1) Basic cross-country routeway analysis modelConsidering the requirement of input, output and others, the paper built some models as following: non-uniform B-spline interpolation model, single map layer trafficability analysis model, map layer overlap model, cross-country routeway analysis model of point to point, point to line and line to line. These models are contacted by grid. Three routeway models are based on the same search strategy, finally the author gave the optimized algorithm.(2) Non-uniform B-spline interpolation modelConsidering good local precision of non-uniform B-spline and good global precision of least square fit method, the paper put forward the non-uniform B-spline least square interpolation model. The experiment shows that B-spline interpolation algorithm has better precision and stability than movable surface interpolation and weighed mean interpolation.(3) Single feature trafficability analysis modelFirst, geomorphy, water system, plant, and settlement place map layers were segmented according to the same size. Then, according to the ablity of maneuver, all the map layers were arranged into three levels: easily pass, hardly pass and impossibly pass, which was labeled with different numbers in terms of the distribution of features and the influence element. Finally we got a trafficability matrix of the corresponding map layer.(4) Multi-feature overlap analysis modelConsidering the overlapping of map layer used the spatial logic operation, the paper used the grid overlapping for reference, firstly gridized the map with the same size, secondly analyzed one map layer's trafficability, finally overlapped the two corresponding grids between map layers in turns. So it can resolve the trafficability analysis of multi-layers easily and efficiently.(5) Cross-country routeway modelThe model analyzed the problem though the following three models: point to point, point to line, line to line Cross-country routeway models. It chooses the graph search strategy of graph...
