サンキ List of Products and Services

Our company has made it possible to use UAVs (unmanned aerial vehicles) to safely and quickly capture high-quality videos and photos in areas that were previously difficult for humans to access. This is particularly effective for gathering information at disaster sites, monitoring construction progress, inspecting structures such as bridges and dams, and conducting cultural heritage surveys. By obtaining three-dimensional terrain data with UAVs, we can minimize on-site survey time and efficiently conduct surveys such as topographic surveys, longitudinal surveys, and cross-sectional surveys. Even for high-altitude inspections, there is no need for scaffolding or high-altitude workers. By using UAVs equipped with obstacle detection systems, we can perform inspection work safely and economically. 【Features】 ■ Minimizes on-site survey time ■ Capable of capturing high-quality videos and photos ■ No need for scaffolding or high-altitude workers for high-altitude inspections ■ Allows for accurate situation assessment and life detection from a distance *For more details, please refer to the PDF document or feel free to contact us.

The Sanki depth measurement system accurately guides survey boats in real-time using GPS (RTK) in oceans and dams. It displays position data from GPS and depth data from the echo sounder in real-time on the screen and saves it to the hard disk. A database of work areas, planned cross-sections, and tide levels is created, and the position data and depth data collected on-site are combined to generate survey data. [Features] ■ Accurately guides survey boats in real-time using GPS ■ Displays depth data in real-time on the screen *For more details, please refer to the catalog or feel free to contact us.

Since January 2016, Sanki has newly introduced the DMT Corporation's autogyro "GYROMAT5000" from Germany, enabling even more precise measurement of propulsion direction than before. Additionally, by using "RTK-GPS" for longitudinal and cross-sectional surveys and mesh surveys, accurate and speedy volume measurements can be performed. Our company responds to technical proposals using GPS for 3D construction and centerline surveys on bridge surfaces. 【Features】 ■ Gyro Surveying - High-precision acquisition of angles from true north - Accurate measurement of the propulsion direction for shield, tunnel construction, and shafts ■ GPS Surveying - Capable of accurately measuring between two points that are quite far apart - Demonstrates power in water and marine observations *For more details, please refer to the catalog or feel free to contact us.

Sanki conducts public surveying primarily for national and local governments. We offer a wide range of services, starting with "benchmark surveying," which serves as the basis for all surveys, investigations, and construction, as well as "leveling" with an observation accuracy of 0.1mm, and "land surveying" to determine land boundaries. 【Main Services Offered】 ■ Benchmark Surveying ■ Leveling ■ Route Surveying ■ Land Surveying ■ Topographic Surveying *For more details, please refer to our catalog or feel free to contact us.

Sanki provides surveying services related to land development, bridges, and construction by introducing new equipment such as autogyros, GPS, and automatic tracking light waves. Please feel free to contact us for any surveying needs at construction sites. We can accommodate requests related to earth volume calculations, construction drawing creation, and more, regardless of the surveying aspect. 【Main Services Offered】 ■ Surveying related to land development: reference points, vertical and horizontal cross-sections, earth volume calculations, setting out, and confirmation surveys ■ Surveying related to bridges: structure positioning, marking, height setting, and alignment ■ Surveying related to construction: positioning, marking, vertical surveying, and area calculations ■ Surveying related to tunnels: direction and position setting with gyros, route surveying, etc. *For more details, please refer to our catalog or feel free to contact us.

A 3D laser scanner is a machine that captures a large amount of point cloud data as coordinate values all at once, allowing for non-contact digitization of visible objects such as natural features, terrain, structures, and urban landscapes, instantly. It can visualize surfaces that are normally not visible, as well as create diagrams from various viewpoints. Since the survey area itself is captured as 3D data, there is no need for on-site diagramming. The "Measurement Service Case Collection" includes various measurement examples such as terrain measurement of 800,000 m², earth volume management at construction sites, cases of landslide disasters, and applications in tunnels. [Featured Cases] - Landslide disaster cases - Measurement in excavation surveys - Measurement examples in plants - Measurement case of Nagoya Castle stone walls - Measurement examples of dams For more details, please contact us or download the catalog.
