摘要
使用佳明(GARMIN)eTrex30(小博士)手持导航型GPS接收机沿调查地块边界绕测自动采集航迹并储存,在ArcMap中通过航迹数据格式转换、投影变换、创建调查地块面要素等操作,能实现地块面积等计算和空间位置成图.结果表明,GPS和ArcGis结合能完成特殊情况下使用图纸勾绘难以完成的面积等调查工作,调查精度高,成图方便.
Using GARMIN eTrex30 (little Doctor) handheld navigation GPS receiver to automatically collect the track along the survey plot boundary and store it, through the track data format conversion, projection transformation, the creation of survey plot surface elements and other operations in AreMap, the calculation of plot area and the mapping of spatial position can be realized. The results show that the combination of GPS and ArcGis can complete the survey work such as the area difficult to be completed by drawing under special circumstances, with high survey precision and convenient mapping.
