摘　　要：在大比例尺地形图生产及更新工作中,传统的人工野外测量方式或单一的航测方式效率低、成本大。本文结合实际生产实践,介绍了利用LiDAR点云数据、倾斜摄影数据、数字高程模型及野外测量成果等多源数据进行大比例尺地形图快速生产的技术方法和工作流程,相较传统方式极大提高了生产效率,节约了生产成本。In the production and updating of large-scale topographic maps,traditional manual field measurement methods or single aerial survey methods are inefficient and costly.Based on actual production practices,this article introduces the technical methods and workflow of rapidly producing large-scale topographic maps using multi-source data such as LiDAR point cloud data,oblique photography data,digital elevation models,and field measurement results.Compared with traditional methods,this approach greatly improves production efficiency and saves production costs.
