We delivered high-accuracy coastal topography to support mangrove planning and environmental impact assessment across more than 100 km\u00b2 at the eastern province shoreline, split into multiple shoreline blocks. Field data collection finished in 1 month, and processing took 2 months, for a total delivery under 3 months end-to-end.<\/span><\/p>\n

<\/span><\/p>\n

The objective was a drone-based LiDAR + photogrammetry topographic map for ecological planning and EIA. Deliverables included GCP and ICP lists, orthomosaic, DSM, DTM, contours, 2D CAD, an Accuracy Assessment, and a Survey Report.<\/span><\/p>\n

Why Is Coastal Topography Challenging<\/b><\/h2>\n

Mapped more than 100 kmsq<\/figcaption><\/figure>\n

Shorelines limit access and introduce safety risks. Above all, tide windows govern when and how long you can work, stretching ground schedules and complicating repeatable measurements. In this context, a traditional approach is very difficult and time-consuming.<\/span><\/p>\n

Approach: Hybrid Drone LiDAR + Photogrammetry<\/b><\/h2>\n

We selected a hybrid workflow to achieve both elevation fidelity and high-resolution textures. A drone survey was chosen specifically to overcome shoreline access limitations while still respecting tidal schedules for data quality.<\/span><\/p>\n
