Services
Tidal Datums
We collect and analyze tidal data using advanced sensors and GNSS technology to establish accurate vertical reference points. Our work supports coastal mapping, navigation, and environmental monitoring. Clients rely on our tidal datum solutions for infrastructure planning and regulatory compliance.
Geodetic Surveys
Our geodetic surveys provide precise horizontal and vertical positioning using GNSS and differential leveling techniques. We support projects requiring integration with the National Spatial Reference System. Applications include infrastructure development, environmental studies, and boundary determination.
Hydrographic Surveys
We conduct hydrographic surveys to map coastal and marine environments using sonar and GNSS technologies. Our data supports navigation safety, habitat assessment, and dredging projects. We deliver bathymetric charts and seafloor analysis for government and industry clients.
GNSS Networks
We design and maintain GNSS reference networks for real-time positioning applications. Our systems support surveying, weather monitoring, and crustal deformation studies. We provide installation, calibration, and ongoing maintenance of GNSS infrastructure.
Coastal Monitoring
Our coastal monitoring programs track shoreline changes and environmental conditions using remote sensing and field measurements. We deploy tide gauges, wave buoys, and meteorological stations. Data informs coastal management and climate adaptation strategies.
