基于计算机的森林调查调绘航片转绘技术研究

结合当前林业调查成图中应用地理信息系统的实际,针对以往航空像片转绘方法的不适应问题,提出了直接用计算机进行航片转绘的新方法和转绘技术流程,并对地理坐标配准、蒙版制作、投影误差纠正、GIS转绘等关键技术进行了论述。

The transfer technique of aerial photos based on the computer in forestry investigation and drawing imaging

As far as the current question that are applications of GIS in forestry investigation imaging and in adaptation to transfer methods of preceding aerial photos is concrned,this article puts forward a new method that computer directly proceeds the transfer of aerial photos and technological process of transfer technique,at the same time,this article also discusses the key techniques,such as matching of geographical coordinates,construction of aerial photos and techniques,such as matching of geographical coordinates,construction of masking-out,correction of projected error and the transfer of GIS.
