3DGS represents a scene as millions of tiny, colored ellipsoidal "splats" floating in 3D space — each carrying position, color, opacity, and view-dependent appearance for photorealistic real-time rendering.

What is 3D Gaussian Splatting?
02
3DGS vs. Traditional Photogrammetry
A head-to-head technical comparison across seven dimensions — rendering quality, processing speed, data size, interactivity, and more — to help you choose the right tool for the task.
03
Can You Measure from a Gaussian Splat?
A precision decision framework for 3DGS deliverables — separating visualization-grade from survey-grade quality, and matching output tiers to project requirements.
Air-Ground Fusion

What is SLAM and Why It Matters?
SLAM (Simultaneous Localization and Mapping) allows a moving sensor to build a map while tracking its own position in real time — making handheld, backpack, and vehicle-mounted laser scanning practical.
02
What is Oblique Photogrammetry?
The aerial foundation of city-scale 3D, capturing multi-angle imagery for complete building facades and urban geometry.
03
LiDAR vs Photogrammetry
A practical comparison of LiDAR and photogrammetry for 3D mapping, covering geometry, visual detail, challenging environments, and when a hybrid workflow is the right choice.
04
What is Air-Ground Fusion?
Get3D's foundational technology enabling seamless integration of aerial and ground-level data — an end-to-end solution combining data acquisition, automated fusion, and intelligent processing.
05
Air-Ground Fusion Advantages
Why air-ground fusion overcomes the coverage and accuracy limits of aerial-only and ground-only 3D capture.
06
Get3D Air-Ground Toolkit
The complete Get3D ecosystem — Mapper, R200 scanner, 5-in-1 camera, and Farm Lite — covering every stage from aerial capture to ground-level scanning.
07
Air-Ground Fusion Case Studies
Real-world city, cultural heritage, and stadium projects where fused aerial and ground capture closed critical coverage gaps.
