摘要
以兖州经济开发区地形图修测工作为例,介绍了地形图修测中没有控制点、只有一个控制点及两个控制点不通视情况下的数字化测图的应用技巧,并对成果进行了检核。结果表明:应用该方法进行地形图修测能满足精度要求,明显提高工作效率。
Taking the topographic map revision of Yanzhou Economic Development Zone as example, this paper introduces the application skills of digital mapping in the topographic map revision with no control point, one control point and two control points under the condition of no inter-visibility and tests and checks the result. The result shows that this skill can meet precision requirement and obviously improve the efficiency.
