Pre-purchase due diligence - any parcel, any country
The land has been changing for months. You just can't see it.
Gradual drift and early-stage construction are invisible to anyone comparing satellite images. GeoValida runs five years of monthly data against a fixed baseline, attributes every zone to its cause, and delivers a plain-language verdict with onset timing - before you make an offer.
Analyze a parcelWhat every report includes
The complete picture. In one run.
5-year monthly trajectory
Monthly satellite composites against a fixed baseline. Not two snapshots - a 60-month history with the seasonal cycle removed, so gradual structural change is visible.
Price heatmap
IDW-interpolated price per m² from deed records, IPTU assessed values, and time-series price indices. What comparable land has sold for, at parcel resolution.
Market listings
Active asking prices from local classifieds (OLX Brazil, Zillow US) overlaid on the map at parcel level. Supply-side context on the same canvas as the satellite analysis.
Legal exclusion layers
WDPA protected areas, Brazilian indigenous territories (FUNAI), quilombola zones, and environmental restrictions from the national registry. Rasterized to pixel level - legally untouchable land is excluded before any ranking occurs.
Zone signals
INVEST, PROCEED, WAIT, or AVOID per spatially coherent zone. Each signal comes with a dominant driver (heat, vegetation, construction, or surface change) and an onset time.
Acquisition brief
400-word plain-language report. Zone reads, risk factors, development dynamics, and a concrete recommendation. No jargon. Every claim backed by a pipeline number.
What GeoValida detects
Two signals that satellite images hide.
Pre-visible construction
Ground-surface changes from clearing, grading, and early paving are detectable 3-6 months before rooftops appear at satellite resolution. That is the entry window - before Google Maps shows anything, before the listing price reflects it.
Gradual structural drift
An area quietly heating up, vegetation slowly retreating - these changes accumulate over months and are invisible to anyone comparing two images. They only appear against a held-fixed, month-matched baseline over five years.
Onset timing
Not just what changed, but when it started. Change detected in the last 3 months is an open entry window. Change from 12 or more months ago means the easy value may already be priced in.
How it works
Four steps. Fully automated.
Define a parcel and a time window. Everything else runs without manual steps.
Define the parcel and time window
Draw any bounding box on the map. Pick the analysis period, typically three to five years. Set the project type. Any location, any country, no setup required.
Five years of monthly data becomes a trajectory
Monthly satellite composites are built and held against a fixed baseline. Each month is compared to the same calendar month in the baseline, removing seasonal cycles. The result is a trajectory - not two snapshots compared.
Each zone is attributed to its cause
The area is divided into zones where the change signal is spatially coherent. Each zone is attributed to its dominant driver - construction activity, vegetation loss, heat stress, or surface change - and given an onset time: when did it start?
Report: signals, plots, price context, brief
A decision signal per zone. Ranked buildable plots with price estimates from local deed transactions. Legal exclusion layers for protected areas, indigenous territories, and environmental restrictions in Brazil. A 400-word acquisition brief in plain language.
Who uses it
Built for acquisition professionals.
Primary tool for directors, analysts, and investors evaluating land before any offer.
Pre-offer due diligence
Know what the land has been doing for the past five years before you make an offer. Pre-visible construction, gradual drift, legal flags - all in one report.
Site shortlisting
Rank every buildable plot across a large area by trajectory signal and price context. Cut a 40-site shortlist to 4 in an afternoon.
Portfolio monitoring
Catch slow degradation before it shows up in valuations. Quarterly runs on held land, with drift signals by zone.
Neighborhood evaluation
For buyers deciding where to live: five years of trajectory data, environmental flags, and what is nearby - not a static map.
