FAQs
To begin your project, Gsource requires UAV or drone images, GCP coordinates, camera metadata, site notes, and any existing survey benchmarks. Additional inputs like LiDAR data or control points may further enhance accuracy.
The timeline depends on ground coverage, number of images, resolution, terrain complexity, and required deliverables. Gsource provides a clear timeline after reviewing your dataset and project specifications.
You can expect orthophotos, Digital Surface Models (DSM), Digital Terrain Models (DTM), classified point clouds, CAD linework, contours, and GIS-ready datasets based on your scope.
With standardized workflows and advanced photogrammetry software, Gsource achieves sub-inch to survey-grade accuracy when supported by high-quality imagery and proper ground control.
Yes. We support data from all major drones and sensors, including RGB, multispectral, oblique, and high-resolution survey cameras.
Absolutely. Gsource provides automated and manual point cloud classification, noise removal, vegetation filtering, and structural identification for engineering and GIS workflows.
Yes. We provide full CAD conversions, feature extraction, 2D/3D linework creation, and BIM-ready models for engineering and construction teams.
Our ISO-certified workflows include multi-stage QA checks, projection validation, elevation accuracy tests, and deliverable reviews by senior photogrammetry specialists.
