【摘要】 提出了渐进式简化建筑物群目标的算法,该算法考虑了目标之间的分辨距离和密度,能够渐进式得到任意比例尺的地图,可以从几何和语义两方面最大限度地保持原有建筑物群的特征,同时可保持综合前后不同分区之间的密度差异。更多还原

【Abstract】 The importance of each building, i.e. weight is quantitated by means of fuzzy comprehensive evaluation method; the map space is partitioned by structural road network; the data structure of each building, originally as an area feature, is built as an oriented point. The typification of building groups is translated into the typification of point groups. The mesh simplification technique can be used in this way. The flow is composed of two steps. Last,an example of building typification based on weighted mesh simplification is given.更多还原
