Satellite evidence of physical change, measured and dated.
Elvermont turns multispectral satellite imagery into independent, defensible evidence of how large sites change.
Scroll to descend ↓
A consistent view of every large site, every few days.
Polar-orbiting multispectral satellites image the whole country at the same local time, building a multi-year archive.
North West England.
One of the sites we have analysed — a representative example, not client work.
Down to 10 m pixels.
Every pixel radiometrically calibrated, cloud-screened and compared like for like, season by season.

0.0 ha of ground cleared or built over since 2018
39.1 ha of new neighbourhood, evidenced capture by capture.
Satellite evidence of physical change, measured and dated.
Elvermont analyses multispectral satellite imagery to measure how land and built environments change — clearance, extraction, construction, restoration — and turns it into independent, defensible evidence for decisions about large sites.
Seven years of change, in one gesture.
Move across the image to compare the same 155 ha footprint in 2018 and 2025. Everything you see is measured: 141.3 ha of change, 91% of the site.

Near-infrared composites from Elvermont analyses — healthy vegetation renders red, bare ground and built surfaces cyan-grey.
Physical change you can see, quantify and defend.
Spectral signatures separate vegetation, bare earth, water and engineered surfaces. Comparing like-for-like seasons isolates genuine change from weather, shadow and the farming calendar.
Clearance & earthworks
Vegetation removal, soil stripping, haul roads and platform construction — mapped and measured in hectares.
Extraction & restoration
Quarry face advance, new extraction cells, stockpiles and the return of vegetation on restored ground.
New built footprint
Housing, warehouses, yards, hardstanding and infrastructure appearing on previously open land.
Energy infrastructure
Ground-mounted solar arrays and associated works, from first disturbance to completed build-out.
Water extent
Lagoons, reservoirs and flooded workings — open-water extent tracked through the short-wave infrared.
Land condition
Vegetation vigour and bare-soil indices over time, separating real change from seasonal variation.
The near-infrared tells a different story.
Plants reflect strongly in near-infrared light the human eye cannot see. Move across the image to look through a spectral lens: vegetation glows red, while new roads, roofs and bare ground stand out in cyan.
- Separates vegetation loss from shadow and colour change
- Reveals construction phases before they look finished
- The same physics drives every index we measure

Bespoke by default. Simple from the first conversation.
You don't need to know anything about satellites. Tell us the site and the decision you're facing; we design the analysis around it.
Talk to us
A short call or email: the site, the period and what you need to know. No forms to master, no software to install.
We design the analysis
We check what the imagery can show for your dates and propose the measurements, outputs and cadence that answer your question.
You receive evidence
Dated, measured, plainly written results — reports, data and imagery — ready to use in your own decisions and documents.
What we deliver today — and where we're taking it.
Every engagement starts from proven capability; bespoke work and new data sources extend it to fit your question.

A versioned, reproducible processing chain.
Every result passes through the same audited steps — from per-pixel cloud screening to independent catalogue verification and analyst review — and is stored with the exact captures and method version that produced it.
Tested blind against official records.
Before offering the method we tested it against an independent UK government register of energy projects, using pre-registered thresholds.
Built for decisions about large sites.
Infrastructure and energy, property and logistics, housebuilding, extraction and restoration, land and environmental advisory, investors and analysts.
