GNSS Satellite Positioning & Leveling Survey
1. High-precision 3D Coordinate Framework
Adopt GNSS satellite positioning technology to establish high-precision three-dimensional coordinate frameworks.
2. Accurate Vertical Datum
Carry out Level 1, 2 and 3 leveling surveys to deliver precise elevation datum.
3. Regional Spatial Skeleton
Lay out traverse & triangular control networks to construct the regional spatial skeleton.
Full-area Topographic Surveying
1. Global Space Reference Frame
Establishment of the coordinate reference framework and unification of the global spatial reference system.
2. Unified and precise spatial reference system
High-scale topographic surveying provides a unified and precise spatial reference system for large-scale engineering projects.
