Photogrammetry
Our Core Solutions
Overview
GeoPro harnesses aerial, UAV/drone, and high-resolution satellite imagery to deliver survey-grade orthophotos, dense 3D reality meshes, and precise elevation models with centimeter-level (or better) accuracy. Our photogrammetry solutions power topographic surveys, urban & infrastructure planning, construction monitoring, environmental change detection, and asset management — providing fast, cost-effective geospatial intelligence that rivals or complements traditional LiDAR workflows.
By transforming overlapping imagery into intelligent, georeferenced 3D products, we help clients visualize terrain and features in unprecedented detail, minimize fieldwork, accelerate project timelines, and support data-driven decisions across local to national scales.
Technical Workflow & Methodology
Our streamlined, scalable pipeline integrates automation and expert validation for reliable results:
- Multi-platform image acquisition (UAV/drone fleets, manned aerial, high-res satellite) with optimal overlap and nadir/oblique angles
- Precise GCP/RTK/PPK georeferencing and bundle adjustment for absolute accuracy
- AI-assisted SfM (Structure-from-Motion) and MVS (Multi-View Stereo) processing for dense point clouds and textured meshes
- Generation of orthomosaics (true ortho), DSM, DTM/DEM, contours, and TIN surfaces
- Automated & semantic feature extraction (buildings, roads, vegetation, water, change detection) using machine learning enhancements
- Time-series/multitemporal analysis for progress monitoring, deformation detection, and environmental trend tracking
- Multispectral & thermal data fusion for advanced analytics (NDVI, material classification)
- Comprehensive QA/QC: vertical/horizontal accuracy (RMSE reporting), edge matching, completeness checks, benchmark cross-validation
