Executive summary<\/b><\/h2>\n
\"Minimal
1 month field, 2 months processing, under 3 months delivery.<\/figcaption><\/figure>\n

We delivered a coastal topographic m<\/span>ap to support mangrove planning and environmental impact assessment across <\/span>102 km\u00b2<\/b> split into <\/span>13 shoreline blocks<\/b> \u0641\u064a <\/span>Jubail and Ras Al Khair<\/b>. Field data collection finished in <\/span>1 month<\/b>. Processing took <\/span>2 months<\/b>. The program concluded in <\/span>under 3 months<\/b> end-to-end, significantly faster than a traditional coastal campaign.<\/span><\/p>\n

Why coastal topography is hard<\/b><\/h2>\n
\"Badge
Missions planned inside tide windows.<\/figcaption><\/figure>\n

Shorelines introduce real operational friction. Access is limited. Safety risks rise. Above all, <\/span>tide windows<\/b> control when you can work and for how long, which stretches ground schedules and complicates repeatable measurements. A conventional approach in these conditions becomes slow and difficult.<\/span><\/p>\n

Method overview: hybrid LiDAR + photogrammetry<\/b><\/h2>\n

We selected a hybrid workflow that combines <\/span>airborne LiDAR<\/b> for structure-through-vegetation and elevation fidelity with <\/span>photogrammetry<\/b> for high-resolution textures and planimetrics. This approach hits accuracy and coverage targets for coastal ecosystems, mangrove planning, and EIA deliverables.<\/span><\/p>\n

      Acquisition strategy<\/b><\/h2>\n

      We divided the shoreline into <\/span>13 blocks<\/b> and scheduled missions inside <\/span>tide windows<\/b> to balance safety and data quality. This playbook completed capture in <\/span>1 month<\/b> and kept datasets comparable across sites despite changing coastal conditions.<\/span><\/p>\n
