01In brief

The short answer.

Reinsurance and Catastrophe tools are the public technical views the platform releases on insurance and catastrophe: 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: from layers to a published mapLayers are ingested with their licences, reprojected and harmonised, analysed (overlay, zonal statistics, indices), checked for uncertainty and published as a map with its passport. Design of the process, not a record of a run.

03Geography

Connected activity in the Gulf of Mexico coast.

For analytical and data resources, in GRA's spatial-finance reading, the map opens on night lights and population density with night lights tonight from NASA GIBS, framed on the Gulf of Mexico coast; every other NASA layer, live feed and forecast waits in the layer list.

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

Reinsurance and Catastrophe maps, models and scenarios.

Reinsurance and Catastrophe tools are released only after review, with sources, time and space reference and uncertainty.

ModelsCat model modules
ScenariosEvent replays

In Reinsurance and Catastrophe, a released map states its hazard layer and resolution, a model its assumptions and validation, and a scenario its narrative, for example back-to-back events against reinstatements. 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.

07Key terms
