Sankyo’s Survey and Design manager Ryo Kumata talked about the results of using the GLT-1000. “Surveying becomes very efficient. For example, traditionally, we conducted an existing condition survey using the total station, but sometimes we had to conduct an additional survey to add details. Meanwhile, the GTL-1000 allows us to conduct a survey and scan to capture point cloud data in a single session. We can therefore complete a survey at one time.” Now the company uses 3D point cloud data at all times. “Since we can determine the heights and layout of the features, which could not be done before with photographs, today we conduct a scan at every site. It is very convenient because we can use visual maps for presentation and deliver data for confirmation to our clients,” said Kumata.

Along with that, Sankyo’s Survey and Design’s Survey Group member Masato Shibuya gave an example of disaster recovery work that required a current condition survey of a prefectural road site that was impassable due to a landslide. “We completed the whole survey process from reference point setup to scanning in just a day. It was quite effortless because we can use it in the same manner as the total station and conduct a scan in a single session. In addition, everything can be done with a single unit. This reduces the number of equipment items so it is helpful for a field engineer.”

Finally, President Otaka talked about the future vision. “We can use 3D point cloud data for various applications, such as a geological survey, vegetation and forest management, and geographical information system (GIS). We are confident that we can expand our consulting business by utilizing it.”
Otaka also revealed his aspiration to “contribute to cultivating young talent by conveying the information of using advanced IT technology in the land survey business.” As part of the efforts, Kumata, who also works as an outside lecturer at Yamagata College of Industry and Technology, uses the GTL-1000 as a case study in his class.
