Controlled DJI intake
Validate Mini 5 Pro capture sets, preserve original source imagery, and send batches directly to object storage through signed upload URLs.
Controlled DJI processing stack
Drone to roofing estimates.
Left Horizon converts structured residential and commercial roof captures into measured geometry, detected items, estimate quantities, and live proposal records teams can keep current.

Technical capabilities
A production path for repeatable roofing estimates.
The system keeps capture intake, processing, schema packaging, and review surfaces separated so each stage can be validated, retried, and audited.
ODX processing pipeline
Queue-safe backend jobs run orthomosaic generation, DSM extraction, image detection, and packaging without tying the browser to long processing work.
Typed proposal records
Measurements, geometry, line items, provenance, and source metadata stay current in the app while large generated assets remain versioned in storage.
Estimator-ready outputs
Roof planes, edges, dimensions, detected items, quantities, and audit trails are shaped for fast estimate review.
From pixels to quantities
Every output carries the evidence trail.
Left Horizon is built around renderable deliverables: a CAD-like plan, detected roof items, estimate line items, and the ODX-generated ortho with overlays.
Roof surfaces
Planes, ridges, hips, valleys, and edges.
Takeoff math
Metric canonicals plus display units.
Versioned review
Current data stays live while generated assets remain immutable.

Processing that looks boring on purpose.
Behind the motion is a durable job contract: bounded uploads, queued processors, typed proposal records, and visible confidence for human review.
