摘　　要：在上海市地下空间调查项目中,为获取存量地下工程的空间位置信息,设计并实施了两套不同目标精度的调查方案。第一套方案通过外业测量获取地下空间要素方位,经矢量化制图等后处理生成最终成果。第二套方案将地下工程竣工图件作为原始资料进行矢量化,经图形配准或基于控制点的坐标转换完成地理空间校正。通过开展地下空间测量实验,评定不同技术途径获取的平面、高程数据精度。实验结果证明了两套方案的有效性与适用性。To obtain information about the location of underground engineering stock in an underground spatial survey project in Shanghai, two sets of different target accuracy surveys schemes were designed and implemented. The first scheme obtains underground spatial location factors using ifeld measurements and produces the ifnal results by vector mapping and other post-processing procedures. The second scheme treats the completed maps of underground construction as original data to vectorize, and then completes geographical spatial correction by graphical matching or coordinate transformation based on control points. Through these experiments of measuring underground location, the horizontal and vertical accuracies of the data were evaluated using various techniques. The experimental results show the effectiveness and applicability of both schemes.
