End to end on the longest path: about 1.1 d of proposed target service levels. Gates wait for the people named; bars with a fading end have no fixed length.

Steps
  1. Area and question

    Find · You · instant
    Draw or upload an area, or pick ADM units · Event window and baseline window · Question: what changed, who and what is exposed
    Geocoder and entity matcher
  2. Search the catalogue

    Find · NXS-GRX run service · instant
    STAC search by area, time and cloud cover · Scenes from the same sensor and processing level · Scene list kept with its query
    Earth-observation pipelineGeocoder and entity matcher
  3. Licence gate approval

    Find · NXS-GRX run service · automatic
    Each source checked in the licence register for the use · Rows under legal review are refused · Attribution and obligations attached

  4. Make scenes comparable

    Prepare · NXS-GRX run service · 1 hour
    Same grid, CRS and resolution · Cloud, shadow and no-data masked · Processing-baseline offsets corrected
    Earth-observation pipeline
  5. Detect change

    Analyse · NXS-GRX run service · 1 hour
    Spectral-index differencing · Damage or change classes with thresholds stated · Masked pixels stay no-data, never zero
    Earth-observation pipelineTested model kernels
  6. Exposure on H3 cells matrix ·

    Analyse · NXS-GRX run service · 1 hour

  7. Spatial checks

Search imagery, pass the licence gate, make scenes comparable, detect change, put exposure on H3 cells and publish a spatial risk product as tiles, with every scene and source in its lineage. The canvas shows where a request stands at the marked job; it is illustrative, not the status of a real request. Durations are proposed target service levels. Select a job for its steps, the people who act, the technology it runs on and what it produces.

સંપર્ક

સ્થિતિ

The methodology, structure and definitions of The Global Risks Index are a preparatory working draft (2026), circulated for review and comment and not for implementation. No value appears until an edition is released from a governed evidence cut; values then carry intervals, classes, sources and their correction pathway. Simulators run the published methods on numbers you choose and never show a NXS-GRX value.

What NXS-GRX is not

NXS-GRX is research and risk-analytics information. It is not a credit or ESG rating and uses no rating scale, not a benchmark for financial instruments, not official statistics, not an emergency warning or official classification, and not advice. It must not be used to evaluate natural persons. Risk classes are bands on a published scale, never rankings of countries or people.

Institutions and sources

The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Every value carries the attribution of its sources, which keep their own licences. External names are cited for interoperability only. Nexus-authored text is intended for CC BY 4.0 on release.

Avis en français

La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
