Job Summary We are seeking experienced Photogrammetry Specialists with a strong technical background in aerial data processing, photogrammetry software, GIS integration, and LiDAR data management. The ideal candidates will be responsible for managing raw drone data, producing high-quality geospatial deliverables, ensuring accuracy through rigorous quality control, and supporting field teams with expert advice. Key Responsibilities 1. Data Management Receive, organize, and archive raw drone data including images, flight logs, and GNSS/RTK/PPK files. Verify the quality of flight logs, metadata, and imagery. Maintain backup protocols and data archival as per company standards. 2. Image Processing Process aerial imagery using photogrammetry software such as Bentley ContextCapture / iTwin Capture Modeler, Pix4D, Agisoft Metashape, DJI Terra. Generate outputs including orthophotos/orthomosaics, DEM/DSM/DTM, point clouds, contours, and 3D meshes. Perform georeferencing using Ground Control Points (GCPs), RTK/PPK data as required. 3. Quality Control Review deliverables for accuracy, alignment, and completeness. Conduct accuracy assessments using RMSE, GCP comparisons, and reprojection error metrics. Reprocess data to ensure compliance with client or internal quality standards. 4. GIS and CAD Integration Import processed drone outputs into GIS platforms like QGIS and ArcGIS, as well as CAD software such as AutoCAD and Civil 3D. Assist in creating maps, overlays, and conducting spatial analysis. Export deliverables in formats requested by clients, including GeoTIFF, DXF, LAS, and SHP. 5. Reporting & Documentation Prepare comprehensive reports detailing processing methodologies, data quality, and final deliverables. Maintain logs of project activities, file versions, and processing parameters. Liaise with drone pilots and project managers to resolve data quality issues. 6. Field Team Support Collaborate with drone operators to optimize flight plans for data capture. Provide technical advice on camera settings, flight altitude, image overlap, and GCP placement. Required Qualifications & Skills Bachelors degree in Geomatics, Geoinformatics, Remote Sensing, GIS, Civil Engineering, Surveying, or related fields. Certifications in Drone Mapping, Photogrammetry, or GIS are a plus. Minimum 5 years of professional experience in photogrammetry and geospatial data processing.
