摘要

本研究利用網形設計概念加入與否進行GPS控制網佈設之外業成本研析，目標在於闡明GPS外業時加入網形設計能以較經齊而有效率之方式進行佈設。本研究採用兩個已經佈設完成之GPS控制網為範例，進行加入網形設計概念與否時，其作業人力、點位平面坐標和高程間之相互比較。由本文研究成果顯示，當加入網形設計概念時，佈設GPS控制網可節省約20%之人力成本且其精度亦符合作業要求規範。

The concept of GPS network design has been used and investigated in this study to compare the field cost with or without it. The goal of this paper is to show that it can be conducted economically for a GPS network, when the concept of network design has been adopted in the field. Two conducted GPS control networks have been used as the field examples to analyze the manpower used and compare the obtained precision of these coordinates and heights. From the obtained results in this article, there is a 20% saving of manpower and acceptable precision with the concept of network design to conduct the GPS control network.
