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 RTK in "river distance marker installation." In this case, network RTK was used to conduct observations of 75 fourth-class reference points during topographic surveying of rivers in Saga Prefecture. On-site checks of the observation values (closure) were performed to confirm the consistency of the observation values, and then calculations for the provisional and practical networks were conducted back at the office to determine the coordinates. In the above scenario (only observation time), the work would typically take about two and a half days if done with total stations, but by using network 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.
