The following table presents typical accuracy analysis carried out over a test field in three different flights:

GCP=0 - no GCPs were used

Super Large Format Enabling Accurate Arial Triangulation

The A3 camera's extremely wide field of view provides an optimal base ratio as well as multiple image overlapping - ensuring high accuracy results in aerial triangulation.

Block Adjustment Using Millions of Tie Points

A3’s processing system is unique in its ability to automatically extract and match millions of tie-points in any given block size, resulting in:

• Robust bundle adjustment
• Excellent photogrammetric accuracy for all frames (including oblique images)
• Direct geo-referencing without ground control and IMU's

Multi-Directional Images

The A3's rotating camera design captures each point numerous times from different angles allowing:

• Exceptionally redundant and computationally stable automatic processing
• Multi-ray photogrammetry enabling highly accurate bundles, DEM and DSM

High Resolution Imagery

The A3 system’s long focal length optics capture high-resolution imagery, contributing to accuracy by:

• Increasing the accuracy of the automatic matching process
• Enabling collection of tie points in areas that would look uniform in lower
resolution
