Run one region's hops through it.
Send the hop list for one region and the clearance envelope you plan against. We will tell you whether the imagery calendar can meet your trim budget date.

With Link Vegetation Monitor
Link Vegetation Monitor estimates canopy height along every hop in your pilot region once a year and ranks the hops by how far the canopy reaches into your clearance envelope.

CH-01 The job today
Where the old method runs out
The path profile was clean the day the link was designed. Since then the trees along the hop have kept growing, and nobody is measuring them. The planner hears about it when signal quality on the hop starts to slip and a ticket comes in, or when a crew visiting for something else notices the canopy has closed in.
Then the question is which other hops look the same, and the only way to answer it is to send people to look. The trim budget has already been set by then.
CH-02 Comparison
Today's method, and what changes
01Deciding which hops need looking at
- Today
- Tickets and fade complaints decide. A hop gets attention when its signal quality drops, or when a crew happens to be at one of its sites.
- With Link Vegetation Monitor
- Every hop in the pilot region gets a canopy estimate along its path, ranked by how far canopy reaches into your envelope.
- Still yours
- Treating a hop as a priority. Our ranking tells you where to look first; you decide what counts as urgent.
02Getting eyes on the path
- Today
- A crew walks or drives the hop, or checks from one end, and writes down what they see.
- With Link Vegetation Monitor
- One annual multispectral pass along each path corridor, so a crew can start with the hops the report points to.
- Still yours
- The site visit. A flagged hop still needs someone to look at the trees before a contractor is booked.
03Measuring against clearance
- Today
- Someone compares what they see against the path profile from the original design, by eye.
- With Link Vegetation Monitor
- The canopy-height estimate is set against the Fresnel clearance envelope you supply, hop by hop.
- Still yours
- The envelope itself. You tell us the clearance you plan against, and the antenna heights.
04Building the trim list
- Today
- The list is assembled from tickets and crew notes, or the whole route gets trimmed because nobody can say which hops can wait.
- With Link Vegetation Monitor
- A flag list sorted by how far into clearance each hop is, plus a trim-priority export for field scheduling.
05Setting the trim budget
- Today
- The budget is set from last year's spend and whatever tickets came in.
- With Link Vegetation Monitor
- The report lands before the annual trim budget is fixed, so you can see which hops are flagged before you commit this year's spend.
- Still yours
- Landowner permissions, contractor choice, and the decision to trim.
CH-03 What you get
What comes back
PDF or CSV
Per-link encroachment report
One entry per hop with canopy height against your Fresnel clearance envelope along the path. Delivered once a year for the pilot region, tied to the ledger rows on deciding and measuring.

GeoPackage
Canopy height estimate along the path
A 3D canopy-height estimate along each hop's corridor, for your GIS team to overlay on the link layer. It is an estimate, and close calls are a reason to inspect.
CSV
Flag list
Hops sorted by how far canopy reaches into clearance, with hop ID and the stretch of path where it happens. It is the list your crew works from.
LedgerBuilding the trim list
CSV
Trim-priority export
The same ranking laid out for field scheduling, so the coordinator can raise work orders in order.

How it works
T1
Hop list in
You send your link paths or hop list, with site coordinates and the clearance envelope you plan against. Mark the hops in the pilot region.
T2Growing season
Imagery
We take an annual multispectral pass along each path corridor, timed to land ahead of your trim budget.
T3
Analysis
Canopy height is modelled along each path and set against your Fresnel envelope.
T4
Delivery
You receive the encroachment report, the flag list and the trim-priority export. We go through the top of the list with you on a call.

What the old method still does better
A crew on site sees the species, the lean of a tree and whether the landowner will let you in. The report sees none of that.
- L01Annual, not continuous
- Growth between passes can outrun the report. A fast-growing stand can close in after the pass is taken, so keep a trim buffer.
- L02It flags physical encroachment only
- The report says where canopy reaches into your envelope. It does not say a link will fail, and it does not read signal quality or fade margin.
- L03Canopy height is an estimate
- It is photogrammetric and carries its own margin. Close calls need someone on site.
- L04Resolution floor
- At 0.5 m a pixel is wider than a twig. We read crowns and stands, not branches, and a single narrow stem near the edge of the envelope can be missed.
- L05Cloud
- A usable clear pass is needed along the whole corridor. Cloud on one stretch can delay a hop, or leave it flagged for a later pass.
CH-06
Who it's for
Switch if
- You plan clearance on point-to-point microwave links and want to know which hops need trimming before a fault ticket tells you.
- You run enough hops that sending a crew to each one every year is not realistic.
- You can name the clearance envelope you plan against.
Stay with your crews if
- You run only a handful of hops and walk them all anyway.
- You want live monitoring of link performance, or a prediction of an outage.
- Your problem is rain fade, equipment or interference, not trees.
CH-07 FAQ
Questions before a pilot
Does this replace the site visit?
No. It tells you which hops to visit first. A flagged hop is checked on the ground before a contractor is booked.
Does it predict a link outage?
No. It flags physical encroachment risk against your envelope. It does not read signal quality or fade margin.
How do we check it against our own records?
Choose a few hops your crews have visited recently and hold back what they found. Compare our flags with theirs hop by hop and decide whether the ranking is good enough to plan with.
How accurate is the canopy height?
It is an estimate from imagery, and we do not quote an accuracy figure. Treat close calls as a reason to inspect, not a certainty.
What about fast-growing seasonal vegetation?
Annual cadence means growth between passes can outrun the report. Plan a trim buffer for the stands that grow fastest.
Can we get more frequent checks?
Annual is the cadence on offer.
Will the files load into our tools?
The outputs are a report, a GIS layer and CSVs keyed to your hop IDs, so a GIS or spreadsheet can read them. We do not write into your link database or work-order system.
Who owns the results and the imagery?
Ownership and licence terms for the deliverables and the imagery are written into the pilot agreement before anything is ordered. Ask for them early if your legal team needs to review.
How is a pilot bought and priced?
We scope and quote a pilot for your region. Tell us how you buy services and we will fit the pilot to that.
