Sentinel · drone inspection platform

AI-driven asset inspection. Built for the field.

End-to-end drone surveys for utility and infrastructure assets — capture, auto-annotate, reconstruct in 3D, and dispatch work orders, all on one platform.

Features

Everything an inspection program needs.

  • AI-powered defect detection

    YOLO26 visual and thermal models auto-annotate captured imagery; pilots review drafts instead of starting from scratch.

  • 3D photogrammetry & orthophotos

    Drop in photos, get an orthophoto, point cloud, and textured 3D model via the built-in NodeODM pipeline.

  • GIS layers & LIDAR analysis

    PostGIS-backed corridor analysis, elevation profiles, and a Three.js point-cloud viewer in the browser.

  • No-fly zone safety

    FAA and AirMap airspace sync, polygon overlays, and waypoint validation before every flight.

  • Work-order automation

    AI findings spawn work orders that auto-assign to specialist or regional teams with SLA tracking.

  • Multi-tenant teams

    Accounts, projects, and roles — built for organizations running their own crews or coordinating contractors.

How it works

From flight to fix, in five stages.

  1. 01

    Capture

    Drone flights or manual uploads. Visual + thermal, georeferenced.

  2. 02

    AI annotation

    YOLO26 detects defects, drafts annotations in W3C format.

  3. 03

    Review

    Pilots and inspectors approve, reject, or refine draft findings.

  4. 04

    Work orders

    Approved findings spawn tickets and auto-route to the right team.

  5. 05

    Reports

    Branded PDF reports per asset, survey, or program — on demand.

Use cases

One platform. Many assets.

  • Power transmission

    Detect cracks, corrosion, and vegetation encroachment along high-voltage corridors.

  • Telecom towers

    Inspect antennas, mounts, and structural integrity without sending climbers.

  • Pipelines

    Survey rights-of-way and detect leaks, encroachment, and exposed sections.

  • Solar farms

    Thermal-scan PV arrays at scale to find hot spots, cracks, and dead cells.
