用无定向导线进行加密控制测量

为恢复委内瑞拉三角洲农产品加工厂区工程控制网,通过合理的布设点位以及采用严密的观测方案,进行了外业数据的采集。利用无定向导线技术和简易平差理论,进行数据分析处理。结果表明,通过该技术所测得的控制点达到了4等以上精度。

An Encryption Control Survey by Using Open Traverse

In order to recover the delta agricuhural products processing factory area engineering control network of Vene- zuela, we have collected the field data by setting points rea- sonably and employing precise observation program. The field data was then analyzed by the astatic traverse technolo- gy and simple adjustment. The result showed that the ob- tained control points had achieved fourth class precision re- quirement.
