Quandao Technology
From field capture to production-ready digital assets
We can carry out UAV surveying, oblique photogrammetry, and on-site imagery capture at the course, or continue from client-supplied aerial data. Deliverables can include orthophotos, DEMs, point clouds, and 3D models, followed by golf course, architectural asset, and real-time engine scene delivery.

Service Capability
An integrated production pipeline built around the final application
Engage us for the complete scope or for selected modules within your existing pipeline. Field capture, spatial data, 3D assets, and engine content are coordinated through one project lead.
Spatial Data Processing
Aerial triangulation, DOM, DEM, and spatial reference preparation.
3D Asset Production
Course terrain, clubhouses, ancillary buildings, facilities, and landscape assets.
Engine Integration
Materials, scene assembly, Unity adaptation, and performance optimization.
From Field to Digital Course
How a real course becomes a production-ready digital course
We can manage the complete scope or begin with client-supplied data. Every stage is aligned to the target product, spatial reference, and delivery standard to reduce repeated processing and multi-vendor handoffs.

01 / Spatial Foundation
A reliable spatial foundation derived from the real course
Unified coordinates, accuracy requirements, and delivery standards make DOM and DEM outputs ready for terrain reconstruction, asset production, and downstream applications.
- Traceable coordinate system, coverage, and accuracy
- Client-defined folders and naming conventions
- Imagery, data, and field references delivered to project scope
02 / Digital Asset Production
Course and architectural assets under one production standard
Based on the target product and runtime environment, we produce terrain, fairways, greens, clubhouses, support facilities, and landscape assets with consistent structure, scale, and naming.
- Coordinated course, building, and facility production
- Unified specifications for multi-course programs
- Client-defined formats, folders, and Unity resource structures
03 / Engine Delivery
A direct path from asset production to engine deployment
Models, materials, and scene hierarchies are organized to the target product specification, reducing rework and handoff friction so deliverables can enter the client's production workflow directly.
- Unity scenes, prefabs, and asset packages
- Stage reviews, version control, and delivery archives
- Custom production with strict project asset confidentiality
Verified Spatial Data
From aerial imagery to verifiable golf course spatial data
Mission planning, field capture, and photogrammetric processing can produce orthophotos, DEMs, point clouds, and 3D models as the spatial foundation for terrain, course, and architectural asset production.
- Approx. 3 cm
- Average visible-light GSD in the sample project
- Evaluated Separately
- Relative accuracy: internal geometric consistency
- Dedicated Validation
- Elevation accuracy: verified with control data or checkpoints
- Project Acceptance
- Coordinates, coverage, error thresholds, and deliverable completeness
Accuracy NoteCentimeter-level results can be achieved under suitable operating conditions. GSD describes the ground sampling distance of the imagery; it is not the same as relative model accuracy or elevation accuracy. Actual targets depend on flight altitude, control method, site conditions, and project acceptance criteria.

Project Questions
How projects move from field capture to accepted delivery
Services can be commissioned as a complete scope or as individual modules. At kickoff, we review available source material, intended use, operating conditions, technical standards, and acceptance methods before defining the production route.
Can your team perform UAV capture at the golf course?
Yes. Based on the course location, airspace conditions, coverage, terrain, and required deliverables, we can plan missions and perform UAV surveying, oblique photogrammetry, ground and building imagery capture, and on-site quality checks. Airspace permissions, weather windows, and course operations are confirmed before mobilization.
Can you continue production from aerial data we already have?
Yes. Before production, we review image clarity, overlap, positioning information, spatial reference, and coverage completeness to determine whether the data supports the required orthophoto, DEM, point cloud, or 3D modeling output. If gaps are identified, we recommend supplementary capture or control information.
Can we commission only a building, one hole, or selected assets?
Yes. A pilot can cover a single hole, local terrain, one building, a clubhouse, or ancillary facilities. Once standards are confirmed, the same workflow can scale to a full 18-hole course, multiple courses, or volume asset production.
Can deliverables follow simulator or engine standards?
Yes. We confirm coordinates, scale, naming, model hierarchy, materials, performance budgets, and resource folders at kickoff. We can deliver Unity scenes, prefabs, and asset packages; specifications for other simulators or engines can be evaluated and implemented from client documentation.
How are project data and source files protected?
A non-disclosure agreement can be signed for each engagement. Raw imagery, coordinate data, source models, working files, and final deliverables are restricted to authorized project members and are not disclosed or transferred externally. Transfer methods, retention periods, delivery archives, and deletion procedures can be defined in the contract.
How are accuracy targets defined and accepted?
At kickoff, GSD, relative accuracy, elevation accuracy, spatial reference, control method, inspection method, and acceptance thresholds are defined separately. GSD describes image resolution and does not directly represent horizontal or elevation accuracy. Final acceptance is based on project control data, checkpoints, processing reports, and the agreed deliverable list.
