摘要：

Map patterns in building groups, as one of the essential foundations for cartographic generalization and multi-scale connection-relations, embodies the relationship of the material form of cities to their social-economic functions. On the basis of related research at home and abroad, a multi-connected linear pattern is recognized taking advantage of parameter discrimination. With the analysis of pattern organization laws, the structural parameters of linear patterns are characterized by distance, direction and size; then the neighborhood relationship was captured by proximity graph with the help of a Delaunay triangulation; finally the multi-connected linear pattern is recognized by pruning the proximity graph, modeling the human processes. Experiments show that this approach is effective, feasible and practicable for multi-connected linear pattern recognition in agreement with cognitive characteristics.
