Live · National LOS audit · every licensed US path
PathFacts analyses microwave paths against LIDAR-derived terrain, vegetation canopy and built structures — delivered two ways, on one analysis engine: a one-time LIDAR survey of the paths you are designing or defending, and Path Monitoring & Analysis that audits your whole network and keeps watching it.
A verified verdict on any path — without the climb, without the drone.
Your whole network analysed now, then watched every night as the world around it changes.
The map is in private beta — accounts are granted individually. Already have one? Sign in. Something else? Contact us.
Service one · LIDAR LOS Surveys
No crew on the tower, no drone mobilization, no waiting on a weather window. The verdict and everything needed to act on it, typically in days.
Verdicts in days, not weeks. No site access to arrange, no crew to schedule, no flight authorization to wait on.
A survey costs a fraction of a tower climb or a drone flight — and the price holds when one path becomes a portfolio.
Bare earth, vegetation canopy, buildings and power lines from LIDAR returns. Nothing is modelled from assumption where a measurement exists.
First Fresnel zone at K = 1.33 and worst-case K = 0.67, earth curvature and diffraction loss, following ITU-R P.530 and P.452.
Every failing or marginal path points at the specific tree stand, structure or line that controls it — and the date canopy growth is predicted to close the path.
Per-path LOS audits and design sheet sets, generated from the stored profile rather than recomputed, so they are reproducible.
Service two · Path Monitoring & Analysis
A path that cleared last year can fail next year without anything on your towers changing. PathFacts analyses your whole network once, then keeps watching every path and alerts you when the world around it moves — so you hear about a problem while it is still a filing, not an outage.
What an alert looks like
Send us your paths — or just your call signs — and get every verdict back at once: pass, pass with notes or fail, the controlling obstruction, and the predicted fail date, with a portfolio report across the lot. Monitoring starts from that baseline.
Watching today
An alert when a new FCC structure registration lands in or near your path corridor — before the tower is built.
Proposed towers, buildings and construction filings that would intrude on the Fresnel zone, flagged at filing time.
New antenna registrations relevant to your path, and modifications to existing ones — height, heading and frequency changes that matter to coordination.
The predicted fail date on every path, recomputed as new vegetation surveys are published — with warning years before the trees close the zone.
Portfolio monitoring
Path Assurance signals Rolling out
The next layer of monitoring, switched on per subscription as each source goes live. Every signal is scored against the stored profile of each path, so it arrives as a clearance consequence, not a raw feed.
Proposed structures from FAA obstruction filings and FCC tower notices, energy projects still in an interconnection queue, building permits and zoning decisions, and corridor parcels zoned tall enough to reach the zone.
An endpoint or corridor parcel changing hands, and site-loss risk at an endpoint: demolition, dismantle, and co-located tenants leaving.
Storms, hail, ice, wildfire, flood and earthquake exposure on your paths, and post-storm inspection lists of exactly which paths to check.
Forecast refraction (k-factor) and ducting risk, with clearance re-run at the forecast k, and a rain-fade nowcast against your fade margins.
Confirmed change in the corridor from new imagery and newly published LiDAR, reviewed before it reaches you.
Degradation in your own NMS telemetry with an attributed cause, and spectrum rulemakings that affect your bands.
One score per path that rolls every signal together, with the explanation and history behind it, and an alert when it moves up a band.
The platform
Survey results and monitoring alerts land in the same place: the map, the portfolio dashboard and the reports. The PathFacts map covers all 130,444 licensed point-to-point microwave links in the United States, with a line-of-sight verdict computed for each one against terrain, vegetation canopy and built structures — sourced from licensing records, terrain surveys, canopy measurements and structure registries, and kept current as new surveys are published.
Every link coloured by verdict, filterable by owner, state, band, length and shape. Click a path for its profile, clearances, the controlling obstruction and the date it is predicted to fail if the canopy keeps growing.
Fresnel geometry at K = 1.33 and worst-case K = 0.67, earth curvature and diffraction loss, following ITU-R P.530 and P.452. Turbines are modelled as a swept sphere, which is the only treatment that catches a path through the blades.
Per-path LOS audits and design sheet sets, plus portfolio reports across any filter selection. All generated from the stored profile rather than recomputed, so they are reproducible.
