| 摘 要： | 依据大量的ＧＰＳ资料指出，测图中在较平坦或低丘地区，除利用其平面信息（ｘ，ｙ）外，还可利用其第三维信息（ｈ）。在不增加额外操作要求（即不增加ＧＰＳ测量成本）的条件下，ＧＰＳ水准高程精度可满足测图对高程精度的要求。这在一定程度上低于只利用ＧＰＳ二维信息（ｘ，ｙ）加上用常规水准测量来获得第三维信息（ｈ）的耗费的成本。

| Abstract: | In this paper, a large amount of GPS data is studied and the result shows that not only the surface in formation (x,y) from GPS may be used but also the vertical information (h) may be used in topomap. The precision of GPS leveling height is able to satisfy the topomap needs under not increasing extra GPS operation (i. e. not increasing GPS survey cost). |
