摘要
随着遥感技术的快速发展,雷达影像测量技术的重要性突显出来,它有力地克服了因测区自然地理环境艰难、气候条件复杂而带来的光学影像无法成图的不利局面,具有效率高、劳动强度低等优点。本文利用RadarSAT-2影像进行1∶50 000 DOM的试验生产,通过具体的生产过程,对雷达影像的数据特点、生产流程、精度指标、生产效率等方面进行了分析研究,为缩短地图更新周期、减少生产成本、提高空间信息获取的实时性提供了方法。
With the rapid development of remote sensing technology, the importance of the radar image measurement technology has e- merged, it effectively overcome the for measuring area natural geographical environment, climate condition is complex and difficult of optical image can "t into the figure of the unfavorable situation, has advantages of high efficiency, low labor intensity, this paper 1 : 50 000 DOM production test by using the RadarSAT 2 image, the specific production process, on the radar image data characteris- tics, production process, precision index, production efficiency and other aspects of the analysis, in order to shorten the map update cycle, reduce production cost, provides a method to improve the real -time spatial information acquisition.
