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.

Pasos
  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. Buscar en el catálogo

    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

  3. Control de licencias aprobación

    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

  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

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.

Estado

La metodología, la estructura y las definiciones de The Global Risks Index son un borrador de trabajo preparatorio (2026), difundido para examen y comentarios y no para su aplicación. Ningún valor aparece hasta que se publica una edición a partir de un corte de evidencia gobernado; los valores incluyen entonces intervalos, clases, fuentes y su vía de corrección. Los simuladores aplican los métodos publicados a las cifras que usted elija y nunca muestran un valor del NXS-GRX.

Lo que NXS-GRX no es

NXS-GRX es información de investigación y analítica de riesgos. No es una calificación crediticia ni ESG y no usa ninguna escala de calificación; no es un índice de referencia para instrumentos financieros, ni estadística oficial, ni una alerta de emergencia o clasificación oficial, ni asesoramiento. No debe usarse para evaluar a personas físicas. Las clases de riesgo son bandas en una escala publicada, nunca clasificaciones de países ni de personas.

Instituciones y fuentes

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.

Cada valor lleva la atribución de sus fuentes, que conservan sus propias licencias. Los nombres externos se citan únicamente a efectos de interoperabilidad. Los textos de autoría de Nexus están destinados a publicarse bajo CC BY 4.0.

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.
