SERVICES
DATA PROCESSING
OGL processes aerial LiDAR and imagery datasets using integrated geospatial workflows designed to support engineering, infrastructure, and environmental projects.
Our processing pipelines combine automated algorithms, specialized software, and experienced geomatics professionals to efficiently handle large-scale datasets while maintaining strict quality control standards and consistent data quality.
SERVICES
GNSS/IMU PROCESSING
Aircraft trajectory and orientation are determined through post-processing of integrated GNSS and IMU data collected during survey operations.
Differential GNSS processing using nearby base stations is combined with inertial data to generate precise trajectory solutions.
These solutions form the basis for direct georeferencing of LiDAR and imagery datasets, ensuring accurate spatial alignment between sensors and supporting reliable downstream products.
SERVICES
AERIAL TRIANGULATION
Aerial triangulation is a core photogrammetric process used to determine the precise position and orientation of aerial imagery across a project area.
OGL performs triangulation using post-processed GNSS/IMU data, ground control points (GCPs), and automatically generated image tie points to ensure accurate alignment of imagery datasets.
This process establishes a consistent spatial framework for all imagery products and supports the generation of reliable geospatial deliverables.
Applications
-
Orthophoto generation
-
Stereo imagery processing

Feature mapping and digitization
SERVICES
IMAGE PROCESSING
Aerial imagery is processed through photogrammetric workflows to produce geospatial products such as orthophotos and stereo imagery.
Processing includes image quality review, radiometric correction, and orthophoto mosaic generation.
LiDAR-derived elevation models are incorporated during orthorectification to improve geometric accuracy and reduce terrain distortion. Final mosaics are reviewed to ensure consistent colour balance and seamless transitions across flight lines and acquisition dates.
SERVICES
LiDAR PROCESSING
Raw LiDAR data is converted into georeferenced point clouds using post-processed trajectory solutions and precise coordinate transformations.
Processing workflows include point cloud alignment, noise filtering, and flight line matching to ensure dataset consistency.
OGL utilizes semi-automated classification workflows combined with manual quality control to identify ground, vegetation, buildings, and other feature classes, enabling efficient processing of large datasets while maintaining high classification accuracy and consistency.
SERVICES
INTEGRATED PROCESSING WORKFLOWS
OGL’s integrated processing workflows ensure consistency between LiDAR, imagery, and trajectory data, allowing for accurate, analysis-ready datasets across all project types.
By maintaining control over the full processing pipeline, OGL reduces data inconsistencies and supports repeatable, high-quality deliverables suitable for engineering design, regulatory reporting, and long-term asset management.
