01In brief

The short answer.

Disaster Risk Finance tools are the public technical views the platform releases on disaster and crisis: maps, model descriptions and sector scenarios, each with its time and space reference, sources, licence and uncertainty. Analysis runs in Nexus Foundry for authorized projects, and data that is not released is not available through these pages.

02Canvas

Scoping to review.

Canvas · scoping to reviewDesign, not a record
Analytical and data resources: build, test and release in Nexus FoundryA request opens a workspace; data are ingested and validated; the model is built and tested on held-out data; an independent gate approves release with limits; the workspace is stood down and the record kept. Design of the process, not a record of a run.

03Geography

Connected activity in Pacific Island states.

For analytical and data resources, in GRA's spatial-finance reading, the map opens on night lights, population density and flood water with night lights tonight from NASA GIBS, framed on Pacific Island states; 3 further NASA layers wait in the list.

The interactive map needs JavaScript; the layer list and sources are below.

Disaster Risk Finance maps, models and scenarios.

Disaster Risk Finance tools are released only after review, with sources, time and space reference and uncertainty.

MapsTrigger zones and assets
ModelsFiscal loss models
ScenariosWaterfall scenarios

In Disaster Risk Finance, a released map states its hazard layer and resolution, a model its assumptions and validation, and a scenario its narrative, for example an event run down the waterfall. Values shown before release are design values.

06Build environment

Working with the tools.

Analysis runs in Nexus Foundry for authorized projects. Public pages show released views only, each with its time and space reference and its rights.
