| 摘 要： | 第二次全国土地调查工作已在各地陆续展开,全面查清土地利用现状,掌握真实准确的土地基础数据是该次土地调查工作的根本目的。利用航测技术,在制作较大比例尺正射影像图的同时,运用测图软件在立体模型上测绘出地类图斑界线,将图斑界线(矢量图)与影像图叠加(套合),绘制出带有地类图斑界线的正射影像图作为外业调查底图。一方面在提高地类图斑界线准确性的同时,提高了地类面积的计算与统计精度;另一方面也有效地提高了外业调查工作效率。

| Abstract: | Second circle land survey has been carried out in many places.How to check present condition of land utilization and grasp correct and basic land datas are major goals in this land survey.By using aerial technology,when orthophotomap with large scales are making,map spots boundary of all types land can be mapped at the same time.Map spots boundary(vectorgraph) and image map are registered together to make orthophotomap with land type map spots boundary as survy map in the field.It can promote correctness of map spots and statistics preciseness of land square,and survey efficiency can be promoted as well. |
