摘要
结合海岸带地形数据修测,对海图、陆图等多种源数据进行融合。经过坐标转换、加密抽稀、数据融合、拼接载切等技术过程,形成了海岸带DEM数据。重点研究了海岸带DEM融合的流程、步骤和算法,为海岸带地形数据的获取与处理提供了思路和经验。
Combining with the revisory survey of the coastal zone, the multi-source data of chart and map is fused. The DEM data can be formed through the process of densifying and reducing, coordinate transforming, data mosaicking and clipping. And the process, approaches and algorithm of DEM fusion are mainly discussed, which provides experience for data acquisition and processing of coastal zone.
