Urban large-scale topographic map is an important guarantee for urban planning and social economic development,moreover the rapid and efficient production of large-scale topographic maps is the exploration direction of mapping geographic information indus-try,so we can better practice in this area to improve because of UAV technology rise. Through a wide range of production practices and accuracy testing, this paper provides some experience and technical reference for 1:500 topographic mapping technology.%城市大比例尺地形图是城市规划和社会经济发展的重要保障,快速、高效地制作大比例尺地形图是测绘地理信息行业一直探索的方向,无人机技术的兴起使我们能更好地在此领域进行实践改进.本文经过较大范围的生产实践、精度检测,为1:500地形图成图技术提供了一定的经验和技术参考.
