摘要：

青海省有色地勘局地质矿产勘查院从2002年至今,在1∶5万水系沉积物测量工作中,将手持GPS的单点绝对定位及航迹运用到野外质量监控,可以较好地解决直接用地形图定点而造成跑错沟,以及由于人为因素导致点位失真、采样随机性大的问题。不仅提高了野外定点精度,而且通过Arcview GIS软件,使管理人员及时了解野外生产进展及采样点的到位情况。定位时必须做到:合理选取校正的控制点;正确校正参数;手持GPS必须一致;航迹必须打开。

关键词: 手持GPS, 水系沉积物, 单点绝对定位, 测量, 质量监控

Abstract:

Since 2002, the single point absolute positioning and track hand GPS have been used in field quality con2 rol by Q IGMR during the 1∶50000 stream sediment survey. The channels pointing mistakes caused by using topographic map and other p roblems such as pointing distortion and samp ling random caused by human factors can be avoided. It not only raises the accuracy of field pointing, but also enables the managers to know p rogress in the field and ccuracy of samp ling through Arcview GIS software. The things must be done during positioning as follows: choose roper correction control points; correct the parameters rightly; conformable hand GPS; turn track on.

Key words: Hand2GPS, Stream sediment, Single point absolute positioning, Survey, Quality control
