摘要
在大比例尺的化探测量中,用GPS单点绝对定点技术来进行测网的布设,减少了控制测量环节,降低了生产成本。因此,GPS绝对定点在化探测量中仍有应用的前景。但是,绝对定位时必须做到:(1)合理选择校正的控制点(三角点或四角点);(2)正确校正参数;(3)定期地检测仪器;(4)保证仪器的高度角和有效工作时间。本次该方法应用在化探的测网布设中,实测面积7 km2,经传统测量仪器检查验收,证明文中提出的方案完全可以用于生产实践。
It abolish control and cost in small - scalee geological survey that locate single geological dots atterly using GPS. Soo absolute fixed position in GPS still have the applied foreground at geologic engineering of the small scale . But must attain: (1) select the control point reasonablety;(2) corret the parameters rightly; (3) examinate instruments; (4) guarantee the instruments with validate to work. We practiced using that methods in the arer.
