US Data Annotators

Geospatial annotation done in the US, by US employees

Full-time annotators on US payroll, working in US infrastructure, under documented chain of custody. Built for defense-adjacent, federal, healthcare, and critical-infrastructure projects where offshore labeling isn't an option.

The status quo

Why teams come to us specifically for US-based annotation

What we deliver

What we deliver, US-only

98%F1 target

On infrastructure asset classes, validated per delivery

Domestic Chain of Custody

Every annotator is a W-2 US employee with a documented background check. No data crosses borders. Full audit trail from capture to delivery.

02

Same-Team Continuity

The annotators on your project this month are the same annotators on it next year. No rotating gig workers, no offshore handoffs that break institutional knowledge.

03

Secured US Infrastructure

CVAT deployed in our US-only environment, optionally inside your VPC. SOC2-aligned controls; ITAR-compliant workflows available on request.

04

Federal-Ready Documentation

Chain of custody, reviewer credentials, and audit logs structured to survive federal contracting reviews. Reviewer CVs available on request.

05

Schema-Ready Delivery

GeoJSON, COCO, KITTI, Mapillary, or your custom schema — with the metadata federal and regulated contracts require.

Before the first call

What you send · What you get

No vague discovery phase. You bring four or five things, we return a specific plan you can evaluate.

What you send
  • 1A representative sample (50-500 frames) from your imagery source
  • 2Target feature classes and geometry types (point, line, polygon, mask)
  • 3Required output format (GeoJSON, COCO, KITTI, Mapillary, custom)
  • 4Approximate volume, deadline, and accuracy requirement
  • 5Security or NDA constraints (we sign mutual NDA up front)
What you get back
  • 1Calibration set with QA scores returned in 2-4 business days
  • 2Documented edge-case log with our interpretation of every ambiguous class
  • 3Schema-locked production scope with per-frame pricing
  • 4Inter-annotator agreement report (kappa, F1 by class)
  • 5Sample report with feature layer, QA notes, and exports
Class library

83 documented asset classes across 4 categories

Every class has a labeled definition, edge-case examples, and QA rules calibrated against authoritative GIS databases. Add custom classes during pilot and we extend the taxonomy.

Road infrastructure
28 classes
  • Pavement markings
  • Striping (single, double, dashed)
  • Crosswalks (all types)
  • Lane lines (direction-aware)
  • Stop bars + yield triangles
  • Road boundaries + shoulders
  • Surface condition cues (cracking, raveling, rutting)
Asset geolocation
34 classes
  • Traffic signs (R-series, W-series, MUTCD-compliant)
  • Traffic signals + pedestrian heads
  • Utility poles (wood, concrete, steel)
  • Streetlights + cobra heads
  • Guardrails + crash cushions
  • Barriers (Jersey, K-rail, temporary)
  • Manholes + catch basins
  • Fire hydrants + valves
Training data extraction
12 classes
  • Object detection bounding boxes
  • Semantic segmentation masks
  • Instance segmentation
  • Polygon classification
  • False-positive cleanup pass
  • False-negative recovery (hard-negative mining)
GIS delivery formats
9 classes
  • GeoJSON (QGIS / ArcGIS native)
  • COCO (training-ready)
  • KITTI (AV-research convention)
  • Mapillary (street-level standard)
  • OpenStreetMap-ready attributes
  • Custom JSON schemas
  • PostGIS direct write
  • Shapefile (legacy support)
Sample deliverable

A single feature, as you would receive it

Every label is a complete GeoJSON feature with geometry, class, confidence, QA trail, and source provenance. Loads directly into your map, your trainer, or your validator — no conversion script.

What you walk away with

How we work

A scoped path from sample data to running system

No open-ended retainers. No "discovery phases" that bill for months without producing anything you can evaluate.

  1. 01

    Sample

    50-100 frames, your schema, your edge cases. We return a calibration set so you can see how we interpret your taxonomy before scale.

  2. 02

    Pilot

    500 samples in 2-4 business days. Inter-annotator agreement scores, QA dashboard, format in your pipeline (GeoJSON, COCO, KITTI, Mapillary).

  3. 03

    Scale

    Production volume with SLA. 24/7 follow-the-sun capacity, 98%+ QA target, weekly delivery cadence.

  4. 04

    Integrate

    Wire into your training pipeline, deploy custom validation rules, build out edge case mining. Optional embedded team.

Why teams trust us
Questions teams ask before they engage us

Common questions, answered honestly

Are you ITAR compliant?

We operate ITAR-compliant workflows for clients who need them. All annotators are US persons (citizens or permanent residents). Infrastructure operates entirely within US borders. We can configure deployment to meet specific ITAR or federal contracting requirements during project setup, including in-VPC deployment in client environments.

How does your pricing compare to offshore annotation?

Roughly 2-3x offshore per-frame rates. The premium covers W-2 employment, US infrastructure, documented chain of custody, and the elimination of the hidden rework cost that comes from offshore quality drift. For projects where offshore isn't viable (ITAR, federal, HIPAA), the relevant comparison is to building an in-house team — we're significantly cheaper than that path.

What kinds of projects fit best?

Defense-adjacent and federal contracting work. Critical infrastructure (energy grid, transportation networks, telecom). Healthcare imagery with PHI exposure. Litigation evidence and regulatory submissions. Any project where the consumer of the annotation needs documented chain of custody from US-based labor.

Do you offer security-cleared annotators?

Yes for specific projects. We have annotators with active clearances available for cleared work, and we can sponsor or sustain additional clearances for long-term engagements. Discuss specific clearance levels (Public Trust, Secret, etc.) during project scoping. Standard projects don't require clearance — we offer it where the work calls for it.
