Services
WGS-84 Implementations
We specialise in WGS-84 aerodrome surveys that meet international aviation standards. Our surveys provide precise geodetic coordinates for airport infrastructure, ensuring compliance with ICAO Annex 14 requirements. With over 280 completed projects across 34 countries, our team delivers accurate data for obstacle limitation surfaces and runway positioning.
Aerodrome Surveys
Our aeronautical surveyors conduct comprehensive aerodrome assessments including obstacle surveys and terrain mapping. Using advanced GNSS technology, we collect data for airspace protection zones and instrument flight procedures. Our surveys support airport safety management systems and regulatory compliance requirements across diverse global environments.
GDMS Software
We develop and support the Geospatial Data Management System (GDMS) for electronic terrain and obstacle data management. This bespoke GIS software enables 3D aerodrome modelling, obstruction analysis, and AIXM format exports. Available as desktop and cloud-based versions, GDMS is used at over 60 global locations for aeronautical data analysis.
Laser Scanning
Our laser scanning services capture detailed 3D data for airport infrastructure and terrain. This technology supports precise obstacle detection and surface modelling for aerodrome safeguarding. The data integrates with our GDMS software for comprehensive airspace analysis and change detection over time.
Surveying
We provide specialist surveying services for aviation and mapping applications. Our capabilities include traditional land surveying, GNSS positioning, and photogrammetric data collection. With expertise in adverse environments, our surveyors deliver accurate geospatial data for infrastructure projects and environmental monitoring worldwide.
