End-to-End Workflow
Our rigorous 6-step pipeline ensures the highest quality outputs from every flight mission.
Mission Planning
Terrain-aware flight planning using DJI Ground Station Pro and custom GCS tools. Optimized for overlap, GSD, and RTK baseline distance.
Data Capture
Systematic aerial data collection with pre-calibrated sensors. Real-time RTK telemetry, flight logging, and GCP placement validation.
Photogrammetry
Structure-from-Motion and Multi-View Stereo processing using Agisoft Metashape and Pix4D to generate orthomosaics, DEMs, and point clouds.
GIS Processing
All outputs processed and validated in QGIS, GDAL, and PostGIS environments. Feature extraction, classification, and attribute enrichment.
QA / QC
Three-tier quality check: positional accuracy verification, visual QC, and attribute validation before final deliverable packaging.
Delivery
Client delivery via secure cloud portal, accompanied by technical reports, metadata documentation, and post-delivery support.
Output Formats
All deliverables are provided in industry-standard formats compatible with major GIS software platforms.
