将森林调查的航片调绘内容转绘到地图上去,目前大多采用目视转绘的方法。本实验选择航片上明显地物点作纠正点,并在地图上求其相应的高程,采用投影转绘仪(又叫单投影器),将航片调绘内容转绘到地图上。结果表明,转绘精度高,速度快,是一种较为理想的方法。 The aerial survey of the aerial painting transferred to map the contents of the transfer, most of the current method of using visual mapping. In this experiment, we select the obvious points of the aerial photos as the corrective points, and find the corresponding elevation on the map. We use the projection delineator (also called single projector) to transfer the aerial image to the map. The result shows that the high precision and fast speed of transfer drawing is an ideal method.
