TEMPERATURE, MEASURED — NOT PHOTOGRAPHED

Every pixel below is a calibrated temperature reading from a drone thermal survey of a solar installation. Hover to read, click two points to compare, or draw a box around any component for its full statistics.

HOW IT WORKS

01Fly

A radiometric thermal camera surveys your roof, array, envelope or equipment in one pass.

02Process

Raw sensor data becomes calibrated per-pixel temperature on Northline-controlled infrastructure in North America.

03Review

Experts analyse the survey — electrical faults, moisture, heat loss — and attest every finding in your report.

The marked findings are our own model's output, not the dataset's labels. Northline vision model v1 (RF-DETR), measured on held-out test imagery: mAP50 0.573 (mAP50:95 0.382) — it finds most defects and misses some, and every finding is reviewed and attested by the consultant before it reaches a report. The temperatures themselves are computed from the raw radiometric counts, not by the model. Temperatures are scan-derived thermographic evidence to support expert review — readings depend on surface and conditions and are not laboratory measurements.
