Survey Services
Integrated survey services for infrastructure, environment, marine, and spatial studies.
1. Land Survey
Topographic Survey
Detailed measurement and mapping of land surfaces for planning, design, and construction. Covers situational detail, contours, and documentation of existing site conditions.
Control Survey
Establishment and densification of horizontal and vertical control points as the measurement framework for land projects and multi-method survey integration.
Dimensional Control Survey
High-accuracy geometry and dimensional measurement of structures or components for installation, fabrication, alignment, and field verification.
2. Hydrographic & Marine Survey
Bathymetric Survey
Water depth measurement and underwater topography mapping using singlebeam or multibeam echosounders for ports, rivers, lakes, and offshore areas.
Seabed & Geophysical Mapping
Seabed feature identification, obstacle detection, and shallow sub-bottom investigation using side scan sonar and sub-bottom profiler.
Coastal & Port Survey
Hydro-oceanographic monitoring including tide, current, wave, and sediment sampling to support port development and coastal protection engineering.
3. UAV Survey
UAV Photogrammetry Survey
Drone-based aerial image acquisition to produce orthophotos, DSM/DTM, and 3D models. Suitable for basemaps, progress monitoring, and efficient large-area mapping.
UAV LiDAR Survey
UAV LiDAR mapping for dense point clouds, including vegetated areas. Supports elevation analysis, volume calculation, and detailed terrain modeling.
4. 3D Laser Scanning
High-Precision 3D Laser Scanning
Terrestrial 3D laser scanning for industrial plants, heritage buildings, and complex civil infrastructure, generating millimeter-accurate point clouds.
Point Cloud Modeling & Inspection
Processing point cloud data into As-Built BIM models, deformation analysis, clash detection, and structural geometry inspection.
