手持GPS测量是目前林业测量的主要方法,通过它与Fugawi软件的配合使用,可以很好地完成各种林业勘察测绘工作,但由于他们各自所用的坐标系统不同在使用过程中必须进行参数校正,传统的校正方法数据资料不易收集,计算方法繁琐,非专业人员难以完成。本文介绍了利用地形图中的三角点对GPS和Fugawi软件进行参数设置方法,并阐述了GPS和Fugawi软件在实际应用中的注意事项,方法简便,实用性强,对使用GPS进行测绘的人员具有一定的参考价值。
Handheld GPS surveying is the main method of forestry surveying at present. Through the cooperation with Fugawi software, it can accomplish all kinds of surveying and mapping in forestry. However, due to their different coordinate system, the parameters calibration must be carried out in the process of using. The traditional method of calibration data is not easy to collect data, the calculation method is cumbersome, non-professionals difficult to complete. This paper introduces the method of parameter setting of GPS and Fugawi software by using triangulation points in the topographic map, and explains the precautions of GPS and Fugawi software in practical application. The method is simple and practical, and has the advantages of using GPS Certain reference value.
