基于91卫图助手软件平台影像与矢量图叠加分析

摘要

基于91卫图助手软件平台,介绍谷歌地球影像与不同坐标系矢量图叠加方法,以一个林场小班矢量图为例,阐述影像数据与小班矢量图准确叠加的操作步骤,帮助使用者解决影像与矢量图叠加应用中的偏移问题.%Based on 91 Assistant Software, taking a subcompartment of a forest farm as an example, the Google Earth image and different coordinate system vector map overlay methods were introduced, the image data and subcompartment vector map exact overlay steps were stated, which help users resolve the deviation problem in the application of image and vector map overlay.
