Mapry Co., Ltd. (Headquarters: Tamba City, Hyogo Prefecture, Representative Director: Keiji Yamaguchi, hereinafter referred to as Mapry), which provides the geospatial information application platform service “mapry”, announced on June 28, 2024 (Friday) that the LiDAR device “LA01” Another model “LA01-model2″ has been released. By increasing the processing speed and implementing a function that allows you to save videos at the same time as point clouds, it is now possible to obtain colored point cloud data more smoothly and with higher precision. This time, we conducted an accuracy comparison and verification with the existing TLS at Shimizu Corporation’s “Thermal Accident Innovation Forest NOVARE”, and utilized the “finished form management using 3D measurement technology” proposed by the Ministry of Land, Infrastructure, Transport and Tourism on this machine. We have confirmed the application to the “Draft Handbook”. Apply Utilization guide for finished form management using 3D measurement technology (draft) Earthwork edition Ground mobile laser scanner (MLS) Verification details On August 9, 2024, data was acquired using mapry LA01 model 2 at the locations where point cloud data was acquired using the existing TLS (Leica RTC360). After that, we checked the horizontal and elevation errors at the verification point (adjust the reference point coordinates between the data to match between TLS and LA01) Result Error within 3-4cm for both horizontal and elevation at the verification point →We have confirmed the applicability of this product to the earthworks section of the Ministry of Land,
Infrastructure, Transport and Tourism’s ICT construction.

By placing one mapryLA01 at the site, you can easily obtain the finished shape of earthworks (surface management), and manage point clouds such as daily soil volume changes and excavation progress. Assumed use case Groundbreaking survey at civil engineering site, as-built survey, acquisition of current topography, slope surface, measurement of excavated soil volume, acquisition of distance between bridge members Coordinate transformation procedure mapryLA01 model 2 is capable of both assigning coordinates using network RTK and converting coordinates at on-site control points. Current status survey, simple survey: This can be easily done using network RTK without the need for control points. Ministry of Land, Infrastructure, Transport and Tourism ICT construction: Please install the designated reflector on the site and measure the center with a TS etc. Point clouds can be generated by performing coordinate transformation on analysis software.

We plan to implement a form creation function for surface management in a future update. Where to apply for product usage https://mapry.co.jp/contact/ Comments from Shimizu Corporation (verification partner company) Until now, at construction sites, it took time to understand the construction status and obtain data using TLS. At NOVARE, our innovation and human resource development base, we will be collaborating to verify 3D data analysis technology using LiDAR to more easily understand the construction site and lead to faster decision-making and construction work. I did. About Maply Maply is a service for everyone involved in surveying, forestry, disaster prevention, agriculture, and construction. We provide solutions that make it easy to acquire, analyze, and utilize 3D data, which has traditionally been difficult to bear due to the expense of surveying equipment and difficult to operate/analyze.
