What Is Right vs What Is Wrong
| COMMON COMPETITOR ERRORS (WRONG) | BLUE PROJECTS GROUND TRUTH (RIGHT) |
|---|---|
| FAIL: Truncated 32-bit floating point coordinates causing spatial jitter over large geographic survey areas | PASS: Full 64-bit double precision coordinates preserving millimeter precision across multi-kilometer scans |
| FAIL: Unassigned ASPRS point classification codes forcing downstream ML models to re-segment ground points | PASS: Exhaustive ASPRS-standard point classification tags for ground, vegetation, and structural elements |
