Capturing the needs of the times
Providing cutting-edge surveying technology

In addition to traditional public surveys, we also carry out surveying work that corresponds to the i-Construction promoted by the Ministry of Land, Infrastructure, Transport and Tourism. In addition, when land acquisition occurs, we respond to customer needs by conducting land boundary surveys and surveys, and investigating and calculating compensation properties.

Representative work and resultsTypical business / results

River channel survey using UAV green laser

UAV green laser surveying can be used for river improvement planning, surveying associated with river channel excavation, and calculating uneven flow. It enables more detailed surveys and can also be used to calculate the amount of sediment and scouring for the planned cross section, as well as to understand the current situation and consider restoration methods in the event of a disaster.
Survey of sediment runoff volume using UAV green laser

By measuring the riverbed topography of lakes and ponds at two different times using a UAV green laser, it is possible to grasp the amount of sediment runoff, which can be used to plan maintenance such as dredging. In addition, by conducting bottom sediment surveys, it is possible to propose issues and investigation methods to concretize future maintenance plans.
Analysis of revetment settlement

By regularly monitoring coastal protection facilities using UAV green laser surveying, it is possible to grasp the amount of changes, etc., and use this information for appropriate maintenance and management to prevent and mitigate disasters.
Maintenance of levees and revetments

By regularly monitoring port and fishing port conservation facilities through UAV surveying, it is possible to understand changes over time and the impact of natural disasters, and use this information for appropriate maintenance and management to reduce and prevent disasters.
Survey of buried waterways

UAV green laser surveying measures the topography of the port and helps understand the status of channels being silted up by sediment to ensure safe ship operation. This can be used for appropriate maintenance and management to prevent and mitigate disasters.
Surveying ruins under the forest

We use UAVs to take photographs and perform laser scanning. Laser scanning allows for topographical surveying within forests, and we create maps using UAV photographs and point clouds. We also create videos from point cloud data.
Preservation surveys of ruins and cultural properties

Terrestrial lasers are used to record and measure cultural assets such as historical buildings and stone walls. Point cloud data can be used to create various drawings such as cross-sections and videos, and can also be used for restoration.
Disaster survey using UAVs

By using UAVs to take aerial photographs of open areas such as rivers, farmland, and coastlines, it is possible to identify widespread damage, identify dangerous areas that are difficult to access, and grasp the scale of the damage. In the 2024 Noto Peninsula earthquake, we responded to the disaster as part of Tec-Force (Emergency Disaster Response Team).
Checking subsidence/uplift conditions and drainage gradients

Using various 3D surveying technologies, it is possible to obtain height information over a wide area and compare it with existing height information to grasp the amount of change. By using contour lines and color-coding to display the height, it is possible to easily check the amount of settlement and drainage gradient.
Land boundary survey, compensation property survey

We investigate and measure the boundaries of land necessary for civil engineering work, and if there are any compensation properties, we also investigate and calculate them.
Earth volume calculation/finished form management

We calculate the volume of soil from 3D point clouds. By measuring data before and after construction, we can perform highly accurate calculations and manage the completed form.
GNSS surveying

Control point surveying and leveling, which are the foundation of surveying, are carried out using multi-GNSS surveying.
UAV photogrammetry

We take aerial photographs using unmanned aerial vehicles (UAVs) and create photographic maps (orthoimages) and 3D point cloud data.
3D laser measurement

Measurements are taken using a 3D laser scanner to create 3D point cloud data of reclaimed land, roads, buildings, etc.
