利用谷歌地球提高乌兰布和沙漠林地测量中的精度

Using Google Earth to Improve the Accuracy of Ulan Buh Desert Forestland Surveys

乌兰布和沙漠地广人稀,环境恶劣,地形复杂,缺少应有的参照物,给测量工作带来的很大的困难,特别是面积比较大的小班,在测量中容易出现精度差等现象。在实际测量工作中,逐步摸索出了利用谷歌地球提高测量精度和准确性,并且取得了较好的效果。文章结合多年的工作经验,依托测量常用软硬件,对测量工作进行了详细介绍,希望对乌兰布和沙漠的测量工作起到抛砖引玉的作用。

The Ulan Buh Desert is sparsely populated with harsh environment and complex terrain,and is short of proper reference materials,which brings great difficulties to the measurement work,especially for sub-compartments with a relatively large area,which are prone to poor accuracy in the measurement and other problems.In the actual measurement work,the use of Google Earth is explored to improve the measurement accuracy,and good results are achieved.The article gives a detailed introduction to the measurement work with common measurement software and hardware on the basis of years of work experience.It is hoped that it can be used as a reference for the survey of Ulan Buh Desert.
