| 摘 要： | 目前,福建省级基础测绘产品1∶10 000 DLG是通过年度更新的方式来维持数据的现势性,主要方法是基于遥感影像对地物进行更新,由于无法及时获取到地面高程信息,因而无法实施地形更新。本文对比分析了LiDAR成果数据,提出了利用LiDAR点云数据成果和基于同时相的点云成果纠正而成的DOM对1∶10 000 DLG进行年度更新的技术路线,为1∶10 000 DLG更新工作开辟了一条行之有效的新道路。

| Abstract: | Currently, the basic mapping products 1∶10 000 DLG is maintained through update , so that keeping the data current poten-tial.The main method is performed based on remote sensing image achieving features , geomorphology temporarily not involved .In this paper, the results of in-depth analysis of LiDAR data , proposed the use of LiDAR point cloud data results and outcomes -based point cloud formed simultaneously with the correct DOM for 1∶10 000 DLG update of the technical route .The proposed method is 1∶10 000 DLG update work has opened up a new path . |
