摘　　要：针对土地勘测定界图中当界址点注记、界址线距离注记密集时容易产生大量压盖,人工处理工作量巨大且容易出错的问题,该文提出采用滑动模型进行注记配置自动优化,界址点注记采用圆形滑动方法,界址线注记采用垂线滑动方法,当常规注记间隔下可能无法找到合适的注记位置时,采用引线注记进行配置,确保地图的易读性,详细分析该算法的流程、实现方法及实例验证。实例表明,该算法效果良好。In view of the problems of dense boundary point labels and boundary line distance labels in the land survey and demarcation map,which were easy to produce a large number of glands,huge manual processing workload and easy to make mistakes,a sliding model for automatic optimization of label configuration was proposed with a circular sliding method for boundary point labels and a vertical sliding method for boundary line labels.When the appropriate label location might not be found under the conventional label interval,the leader label was used to ensure the legibility of the map.The algorithm flow and implementation method of the sliding model were analyzed in detail.Examples showed that the algorithm was effective.
