Satellite + public-record due diligence
▚ measuring soil texture…
No account required for your first analysis. Or browse land data by county.
Most tools hand you a report and disappear. Land keeps changing after you buy it — that is the part that costs money.
Before you visit
Draw any parcel on Earth and get a verdict in about a minute — flood history, slope, usable acreage, soils, hazards, what sits next door. Walk away from the bad ones before you spend a dollar on travel, a survey or a perc test.
Analyze a parcelAt the decision
Compare the finalists side by side. Work the checklist of things no satellite can settle — title, easements, water rights, perc. Ask the expert questions about your own report. Hand the PDF to your lender, your agent or your lawyer.
See the methodAfter you close
Tell us you own it and we re-measure it every day — new standing water, vegetation coming off it, a fresh burn scar, a verdict that moves. You get an email when something changes, and a timeline of every measurement we have ever taken of that ground.

Draw a parcel anywhere on Earth. We measure it directly — radar and optical satellite imagery, elevation models, soil surveys and public registries — computed for your boundary, not copied from a listing.
02 · signals resolving
Every conclusion arrives with its working: what we observed, why it matters, how it was computed, when the imagery was taken, and the published method or agency source behind it.
03 · every value cited and dated
What a satellite physically cannot settle — title, easements, zoning, water rights — goes on a human-verify checklist. We route it to you; we never guess it.
LandBenchmark measures any parcel on Earth — flood history, slope, soils, hazards, what sits next door — and goes deepest in the US, where federal layers like FEMA flood zones and USDA soil surveys take a parcel from 36 checks to 56. Every value carries its method, its source and the date it was observed. What we cannot measure, we say so.
The full framework covers 84 factors a land buyer weighs. 56 are measured live today from satellite and public data — each with a published method, a source link and its trust limits stated.
Everything below is live today. Pro features are marked.
Monitoring
We re-measure watched parcels every day and email you what moved — not a re-reading of an old report, a fresh measurement.
Timeline
Every measurement we have taken of your land, plotted. Days we could not measure render as gaps — we never draw a line through them.
Compare
Put your finalists side by side, signal by signal, and see exactly where they differ.
Checklist
The questions that kill land deals — title, access, perc, water rights — matched to this parcel's flags, with who to call.
Expert
A land-quality assistant grounded in your parcel's measured evidence, not in generic advice. Ask what a signal means, or why the verdict went that way.
Lookup
Owner, acreage and legal description from the county record — no account, no card.

Accuracy
We publish how often we are right, and say so plainly where we have never checked. No competitor does this.

Most land tools fill gaps with estimates and call it coverage. LandBenchmark's rule is stricter, and it is the entire product: a value appears on a report only when we actually observed it — and it carries the evidence to prove it.
The same rule applies to this page. No testimonials, no invented user counts, no fake urgency — just what the product measures and how.
No placeholder numbers, ever. A parcel where nothing could be measured returns a pending report — never a dressed-up guess.
Every live value states when it was observed — the sensor, the imagery window and the resolution it was read at.
Every signal names its method and its source — peer-reviewed science or the responsible public agency, with a link.
Trust limits are disclosed on each signal, and the verdict is a screening call — not a survey, appraisal or flood determination.
Anywhere on Earth. The core satellite, terrain and climate signals are global; parcels in the United States get additional depth from federal datasets — FEMA flood zones, USDA soil surveys, USGS seismic design values, EPA registries. Each signal on a report states its own coverage and the dataset it was read from.
It is a screen, not a determination. Green / caution / walk-away summarises which measured signals raised flags, so you know where to dig before paying for surveys and site visits. It is not a survey, an appraisal or a flood determination — and if nothing could be measured, the report says pending rather than pretending.
Public, citable sources: Copernicus Sentinel-1 and Sentinel-2 imagery, Copernicus and USGS elevation models, ERA5 climate reanalysis, NASA MODIS, ESA WorldCover, USDA soil surveys, FEMA, NOAA, EPA and OpenStreetMap, among others. Every signal on every report links the source it was computed from — the full list is on the methodology page.
Anything that lives in paper records rather than on the land: title and liens, deeded access and easements, zoning, mineral and water rights, soil bearing capacity. Those 8 checks appear on every report as a human-verify checklist — flagged for you, never estimated.
No. You can draw a parcel and run your first analysis without signing up. A free account adds saved analyses, a dashboard, the human-verify checklist — and your first full satellite report, free.
That is half of what it is for. Tell us a parcel is yours and we re-measure it every day, keep a timeline of every measurement, and email you when the land changes — new standing water, vegetation coming off it, a fresh burn scar, a verdict that moves. Land does not stop changing the day you buy it, and nobody sends you a letter when it does.
Screening a parcel is free, and so is the checklist that comes with it. Pro — the full satellite report, the land expert, daily monitoring of your land and its timeline — is $19 per month after a 3-day free trial, and you can cancel in one click. See the pricing page.
About a minute from boundary to verdict — every value dated and cited. No account required. If you buy it, we keep watching it.
