Biodiversity Nexus · Map workspaceMap workspace, in outline: domain structure with placeholder names and illustrative values, not a record.
Biodiversity Nexus released maps are reviewed map views of biodiversity and nature, published once their data rights are cleared, each with its coordinate reference, date, sources and uncertainty. Layers draw on sources such as IUCN Red List of Ecosystems. A map shows released, rights-cleared evidence, not a live feed or an official warning.

Mountain ranges, deserts, wetlands, glaciers and reefs, and how remote each division is from large cities, shown for Colombia as an example geography for this subject.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Coordinate reference system | The definition that ties coordinates to locations on Earth, catalogued with EPSG codes. |
| Modifiable areal unit problem | The change in statistical results that comes from how areas are drawn and aggregated. |
| Zonal statistics | Statistics of raster values summarised within boundaries such as districts. |
| Public-safe release | A recorded decision on the detail at which a layer may be published without exposing sensitive sites or people. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
