摘　　要：卫片或者谷歌等遥感地图对县级林业勘测工作越来越重要,但是卫片或者遥感地图存在像素低、地图更新慢、内业质量差等问题。通过选择大疆精灵4RTK作为林业航测机以及无人机操作准备、遥控器设置、低空-摄影测量2D-规划飞行等技术取得航测照片,最后利用高端配置的计算机和Pix4Dmapper软件成功合成二维高清tif(tiff)地图照片,合成后的地图照片可以直接加载到Arcmap10.2上作为底图使用,可以和卫片、谷歌影像地图完美叠加,相互对照使用,分辨率至少是17级谷歌地图影像的10~20倍。Remote sensing maps such as satellite photos or Google are becoming more and more important for county-level forestry survey,but satellite photos or remote sensing maps have some problems,such as low pixels,slow map update,poor quality of office work and so on.By selecting DJI Phantom 4 RTK as forestry aerial survey machine and UAV operation preparation,remote controller setting,low altitude-photogrammetry 2Dplanned flight and other technologies,aerial survey photos were obtained.Finally,the high-end computer and Pix4Dmapper software are used to successfully synthesize 2D high-definition tif(tiff)map photos,and the synthesized map photos can be directly loaded into Arcmap10.2 for use as basemaps.It can be perfectly superimposed with satellite images and Google Maps,and used in comparison with each other.The resolution is at least 10-20 times that of the 17th grade Google Maps.
