Introducing observation examples of 75 Class 4 reference points in the topographic survey of rivers in Saga Prefecture!
We would like to introduce a case study by Kyushu Surveying and Design Co., Ltd. that utilized network-based RTK in the installation of river distance markers. In this case, network-based RTK was used to observe 75 fourth-class reference points during topographic surveying of rivers in Saga Prefecture. On-site checks of the observed values (closure) were conducted to confirm the consistency of the observations, and then calculations for the provisional and practical networks were performed back at the office to determine the coordinates. In the above-mentioned work (observation time only), it would typically take about two and a half days for work done with total stations, but by using network-based RTK, the work time was reduced to 7 to 8 hours, achieving a significant reduction in work time (with good visibility overhead). 【Benefits and Effects】 ■ Cost reduction compared to conventional reference point surveying (work can be done by one person). *For more details, please refer to the PDF document or feel free to contact us.
