This engineering platform is entirely decoupled from international ski resorts, property sales, or residential real estate brokers. We focus exclusively on geodetic sciences, providing professional land surveying, mapping of steep or uneven terrains, and technical calculation of gravity-fed stormwater drainage channels for agricultural properties and rural developments.
High-precision control networks and boundary surveys using static GNSS and total stations, tied to national datums for long-term consistency.
Contour mapping at 1:500 scale with 0.5-meter intervals for steep hillsides, dense vegetation, and uneven agricultural terrain.
Hydraulic modeling using Manning's equation for gravity-fed stormwater drains, including cross-section design and erosion control.
Practical observations and guides on geodetic surveying, terrain mapping, and rural drainage engineering.
This page frames a concrete subject instead of using a generic heading. It explains what is being considered, why it matters in the site's context, and what detail a reader can expect next. The copy is intentionally plain and specific, so it reads like a real content item.
Read article →This item focuses on practical use, tradeoffs, and decisions that a reader may recognize. It avoids broad promotional claims and keeps the topic tied to a clear situation. The description gives enough substance for a real page rather than a placeholder card.
Read article →This page gives the third item its own reason to exist. It covers a separate angle, includes concrete context, and avoids repeating the same promise in different words. The result should feel like a planned article, project, review, or offer.
Read article →Each capability is built around field conditions, not theory. We deliver survey data and drainage calculations that contractors and engineers can use directly.
RTK-GNSS and total station surveys for parcels with slopes above 20 degrees. We produce 1:500 scale maps with 0.5 m contour intervals, digital terrain models, and cross-section profiles for drainage design.
Manning’s equation calculations for open-channel networks serving 10–50 ha agricultural zones. We determine channel cross-sections, flow velocity, freeboard, and erosion control requirements for 10-year storm events.
Permanent monument installation with static GNSS observations tied to national datum. Millimeter-level adjusted coordinates for cadastral surveys, boundary demarcation, and multi-year land consolidation projects.
Our work is grounded in geodetic science, not real estate. Every survey, map, and drainage calculation is built for rural and agricultural terrain.
We don’t rely on satellite imagery alone. Every contour line is checked with total station or RTK-GNSS on the ground, especially on slopes above 20 degrees where automated models fail.
Our channel designs use Manning’s equation with real surveyed slopes, not generic assumptions. We calculate flow capacity for 10-year storm events and specify erosion control where needed.
For multi-year land projects, we establish monumented control points tied to the national datum. This ensures every future survey, boundary, or infrastructure layout aligns within millimeters.
Trusted by agricultural cooperatives, rural municipalities, and land consolidation authorities across Hokkaido and the Furano basin. No property listings, no ski resort data — only geodetic engineering.
Geodetic surveys, drainage calculations, and terrain mapping — selected items from our field work.
12-hectare hillside parcel mapped with RTK-GNSS and total station. 1:500 contour intervals at 0.5 m. Digital terrain model delivered for drainage design.
