Legality assessment software: one clear outcome for every plot
Legality assessment software takes the polygons you already hold — supplier farms, candidate sites, a portfolio of fields — and checks each one against the records that determine whether land may be converted or used: protected areas, Indigenous and community lands, World Heritage and biosphere sites, protected wetlands and threatened-species occurrences. Each plot receives one outcome and the strictest restriction tier behind it. ERWAY Legality Assessment is that software, and this page explains what it screens, how it decides and what the export contains.
Four of the five sources decide the outcome; threatened species are shown alongside it and never enter it. The outcome scale has five steps — No findings, Informational, Verification needed, Restricted, Prohibited — and six tiers, 1 strictest to 6 weakest. A plot takes the most serious finding across the deciding sources; a project takes its most serious plot. The rule is the same for every customer, so two people looking at the same polygon see the same result. See the protected-area screening and the World Heritage and wetland check for what each source contributes.
What is screened
Polygons, in GeoJSON or drawn from coordinates. The plot's own properties — a supplier's plot code, a cadastral reference — become its identity in every table and every export. A plot without geometry is kept and marked 'Not assessable', which the product never treats as 'No findings'. Five checks are queued per plot on save and run in the background, one queue per source.
How the outcome is decided
Each source answers for itself: an overlap with a strict-protection area is tier 1 and prohibited; a sustainable-use area or an official wetland boundary is tier 3 and restricted; an international designation without settled terms is 'Verification needed'. The plot's outcome is the worst of those answers, never an average. The page names which sources decided, so a reviewer sees not only the result but its reason — the outcome scale and tier scale are shown next to every finding.
What the export carries
CSV for the page or for every matching plot, and GeoJSON with the plot's geometry and a findings array. Every finding travels with its source, its tier, its overlap in hectares and the date the source was checked. The file is what a credit analyst, an auditor or a consultant reads next; exports are logged with the user and the time.
What it is not
Not a legal opinion, not a field survey, not a critical-habitat determination and not a cadastre lookup. The outcome is a preliminary screening against international protection records; where a national register is the authority, the page tells you to consult it. The line between a desktop screening and the specialist work that follows is drawn on the screening tool versus consultancy page.
