Drone Data Acquisition for Photogrammetry Survey – Industrial Plant, Barbados

This project involves drone-based aerial data acquisition at an industrial plant located in Barbados. The primary objective is to capture high-resolution aerial data suitable for photogrammetry processing, including the generation of orthophotos, 3D models/meshes, and point clouds. The contractor’s scope is strictly limited to the field data acquisition stage, while all post-processing activities will be carried out by the client. Therefore, the quality, accuracy, and completeness of the captured data are critical to ensure successful downstream processing. The contractor shall execute the survey using a high-resolution UAV system capable of delivering photogrammetry-grade data. The operation includes mission planning, aerial data capture, establishment of Ground Control Points (GCPs), and georeferencing of the dataset. The survey must be conducted using two flight methodologies. An orthogonal flight shall be performed for orthophoto generation with a nadir camera angle, while a double-grid flight shall be executed to support 3D model and mesh generation with an oblique camera angle. A minimum image overlap of 80% must be maintained across all flights, with a maximum flight altitude of 90 meters. A minimum of eight Ground Control Points must be established on-site. These points must be clearly visible in the imagery and accurately surveyed to ensure proper georeferencing. The contractor is responsible for recording and submitting GCP data along with the captured dataset. All operations must be conducted in compliance with industrial safety standards. The contractor must ensure that all personnel are equipped with required PPE and that all necessary permissions and documentation for site access are obtained prior to execution. The final deliverables from the contractor shall include complete raw aerial imagery, flight logs, and a georeferenced GCP report. The data must be free from gaps, blur, or inconsistencies and must meet the quality standards required for photogrammetry processing.
