Ground motion · Surface change · Slope · Terrain · Drainage. One cell read through every layer.

One site, every layer

## Ground motion, surface change, slope and terrain on one grid.

Your records and the public evidence for your ground are placed on one grid, so every layer answers the same question at the same place. Shown: vertical ground motion from satellite radar across an upland site, millimetres a year.

- 4
  
  **Signals on one 50 m grid**Water held in the terrain, surface change from LiDAR, ground motion from radar, and soil depth with a band.
- 3
  
  **Ways to read condition**Working classes at 1 m, a satellite read at 10 m, and one harmonised score, side by side, with the cells where they disagree.
- 1
  
  **Plan for where to look next**The cells to check first, and a probe or survey plan with its expected gain stated in advance.

From scoping to consent

## Evidence for every subsidence and ground decision on a site.

1. ### Site selection and due diligence
   
   Ground motion, surface change and mining legacy across the whole search area, so the option you sign is on ground that holds. [See a live site read →](https://www.vireonature.com/inside-a-site)
2. ### Coal Mining Risk Assessment
   
   The ground evidence your competent person needs on day one: motion, surface change, terrain features and the site history, on one grid.
3. ### Subsidence and settlement
   
   Satellite radar to about a millimetre a year, read with terrain and soils, so settling ground is flagged before design. [Ground motion guide →](https://www.vireonature.com/insights/egms-ground-motion-desk-study)
4. ### Slope stability and landslides
   
   Slope, drainage and soil depth read together, so the hazard assessment starts on the cells that matter. [Landslide guide →](https://www.vireonature.com/insights/peat-landslide-risk-assessment-scotland)
5. ### Coal tips and spoil heaps
   
   Slope, drainage, surface change and ground motion for every tip, with repeat reads that show what has changed.
6. ### Roads, rail and pipelines
   
   Moving ground read kilometre by kilometre along a route, then watched through design and construction. [See a corridor read →](https://www.vireonature.com/inside-a-corridor)

Why this matters

Before anyone goes to site, someone has to decide where to focus. The records exist: borehole logs in a spreadsheet, a mining report in a PDF, a boundary in a GIS file. The pack reads them together and answers the question.

Decision summary

### What the evidence supports, and where to firm it up

Main findings, the key uncertainties, and the recommended next step, written for the person who has to sign off the budget.

Site evidence maps

### Every layer on the same grid

Peat and soil, terrain and wetness, satellite condition, surface change and ground motion, water and catchment context, read on one 10 m grid, 1 m where LiDAR is held.

Your records, in context

### What you supplied, how it was used

Each file checked for format, coverage, date, licence and relevance, then placed on the same grid as the public sources. Not an attachment at the back.

Evidence register

### Source, date, licence, limitation

Every figure carries where it came from, when, under what licence and with what evidence tier, so it can be explained to colleagues, clients, funders or regulators.

Survey-priority plan

### Where to look next, in order

The cells where the reads disagree, the gaps in your records, and a walkable plan for probing, monitoring or assessment, with the expected gain stated before anyone walks it.

Handover call

### Thirty minutes on the findings

One factual-correction round and one call to walk through the pack and agree the next step.

What a site check looks like

## Subsidence and ground movement, read by the Vireo Neural Map.

A working quarry read from orbit, surface change between LiDAR surveys, slope across a hillside and the drainage lines that cut it. Different questions, one method. Your pack carries the layers that matter for your decision.

![A 400 hectare quarry: 268 satellite radar points coloured by vertical ground motion 2020 to 2024, with the site boundary and recorded heritage](https://www.vireonature.com/hs-fs/hubfs/pp_g_mining.jpg?width=1000&height=1000&name=pp_g_mining.jpg)

**A working quarry, read from orbit**268 radar points over a 400 ha site, vertical motion 2020 to 2024, with the boundary and recorded heritage on the same grid.

![Surface change in centimetres between two LiDAR surveys across an upland site](https://www.vireonature.com/hs-fs/hubfs/pp_sa_lidar.jpg?width=1400&height=1270&name=pp_sa_lidar.jpg)

**Surface change between surveys**Two LiDAR surveys compared cell by cell, in centimetres. Ground that has dropped or built up shows before anyone walks it.

![Slope read from 1 m terrain across a hillside](https://www.vireonature.com/hs-fs/hubfs/sy_pb_slope.jpg?width=1146&height=994&name=sy_pb_slope.jpg)

**Slope across a hillside**Slope from 1 m terrain, read with drainage and soils, so stability work starts where the ground is steepest and wettest.

![Drainage lines and micro-relief from 1 m terrain cutting across a slope](https://www.vireonature.com/hs-fs/hubfs/sy_pb_micro.jpg?width=1146&height=994&name=sy_pb_micro.jpg)

**The lines water follows**Drainage channels and micro-relief from 1 m terrain. Where water runs across a slope or tip is where it weakens first.

How it works

## Send a boundary and your records. Get back a pack and a plan.

1. ### Send a boundary and your decision
   
   One boundary, the decision you need to make, and a note of the records you hold. We confirm the site fits before you order.
2. ### We read your records with the public evidence
   
   Up to ten of your files and the public evidence for that ground, placed on one grid and read together.
3. ### Pack in your hands
   
   The pack, one factual-correction round and a 30-minute handover call on the findings and the next step.

Who it is for

### Developers on the coalfield

Mining legacy and moving ground settled before an option is signed or a layout fixed.

### Geotechnical and engineering consultancies

A ground investigation brief written on evidence, with a record a reviewer can check.

### Asset and tip owners

Slopes, tips and linear assets prioritised from one record, read again as the ground changes.

Launch offer

## Ten sites at the launch price.

The pack briefs, and sits alongside, the ground investigation and risk assessment your engineer signs.

£3,600£9,600Per qualifying site

Excluding VAT where applicable. The standard Site Evidence Pack price is £9,600 a site. The first three launch sites are delivered and reviewed before the remaining seven places open.

**One site, one question**Give us one boundary and the decision it serves. The whole pack is built around that question. Several sites are quoted together.

**Your data stays yours**Your files are used for your assessment only. Contributing them to research is your choice, under a separate agreement, and earns £500 credit.

**We confirm your site first**We check geography, coverage and size before you order, and tell you plainly whether it fits.

Questions

Prices exclude VAT where applicable. Example outputs are from one anonymised upland site and show the format of your pack.

When does a site need a Coal Mining Risk Assessment?

When it sits in the Mining Remediation Authority Development High Risk Area, most planning applications need one. It must show the site can be made safe and stable, and is signed off by a competent person. Vireo gives that person the ground evidence on one grid from day one: ground motion, surface change, terrain and the site history.

How does Vireo measure ground movement?

From satellite radar. The European Ground Motion Service measures vertical and east-west motion to about a millimetre a year. Vireo places it on the same grid as 1 m terrain, LiDAR surface change and your own records, so moving ground is read in context, not as dots on a map.

Can it read coal tips and spoil heaps?

Yes. Slope, drainage, surface change and ground motion are read together for every tip, with repeat reads that show what has changed between surveys. Owners and inspection programmes get one record to prioritise from.

How does it fit with ground investigation?

It comes first and aims it. The cells where motion, slope and surface change line up are where boreholes, trial pits and inspections earn the most, so the investigation brief is written on evidence.

Does it cover roads, rail and pipelines?

Yes. The Corridor Evidence Pack reads a route kilometre by kilometre, with ground motion, crossings and constraints on the same chainage, then watches the moving kilometres through design and construction.

What does it cost?

£3,600 a site at the launch price and £9,600 a corridor, excluding VAT, each credited against the assessment that follows. Monitoring programmes are quoted on the assets you send.
