Utilizing the single-point observation method of network RTK-GPS surveying in the field of geodetic surveying as public surveying!
We would like to introduce a case study by the City of Tondabayashi, Osaka Prefecture (in cooperation with Asahi Koyo Co., Ltd.) regarding the "Construction of a Surveying Work Manual," utilizing reference points (star measurement points) through network-type RTK single-point observation. To conduct third and fourth-class reference point surveys, which form the backbone of construction surveying, as public surveys, it is necessary to use higher-level national reference points or public reference points as known points. However, in areas where the density is not sufficiently developed for efficient use, there can be an excessive financial burden. As a result, these surveying works may not be applied to the Geospatial Information Authority of Japan as public surveys, and the surveying results have rarely been utilized beyond the specific construction projects. 【Solution】 - Developed a single-point observation method using network-type RTK-GPS in collaboration with Asahi Koyo Co., Ltd. in the field of geodetic surveying. - Received advice from the Geospatial Information Authority of Japan based on the application under Article 16 of the Public Survey Work Regulations. - Utilized the single-point observation method of network-type RTK-GPS surveying as public surveying in the field of geodetic surveying. *For more details, please refer to the PDF document or feel free to contact us.
