【摘要】 针对传统地形测图方法效率低下的问题,该文提出半数字化地形测图的实习教改方案。选择在模拟地形测图与数字地形测图之间折中,即采用数字化测绘仪器,但仍采用模拟测图的数据采集方案。观测数据不记录在仪器存储卡中,而是记录在观测手簿。为提高绘图时展点速度,提出改传统极坐标展点为直角坐标展点,并研制了一套直角展点尺和展点新方法。新展点尺根据坐标50m的余数快速展点,并在展点尺的右上角留有1/4圆弧,可提高展点精度。试验结果显示,直角坐标展点比传统极坐标展点在精度和速度上均有优势。更多还原

【Abstract】 For that highlighting mapping details and enhancing the efficiency of execution in topographic mapping internship,this paper put forward a semi-digitized topographic mapping internshi Pscheme,which was compromised between simulative topographic mapping and digitized topographic mapping.Although the scheme adopted digital instruments,the data acquisition still used old method in simulative topographic mapping.The data was gathered and recorded in table.For cutting down the time consuming in plot,a new coordinates mapping method was proposed based on coordinates ruler that invented by this paper.The plot work was speeded up based on remainder of 50 m by using new ruler,and a quarter of a circular arc at the top-right corner could enhance the accuracy of plot.Experimental results showed that this method was better than traditional scheme.更多还原
