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.

步骤
  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. 搜索目录

    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. 许可门槛 审批

    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
    Population and assets aggregated to H3 · Totals conserved across resolutions · Change overlaid on exposure
    H3 exposure kernelsTested model kernels
  7. Spatial checks

    Check · NXS-GRX run service · automatic
    CRS and units checked end to end · Withheld features counted · Accuracy assessed on held-out areas
    Verification engineProvenance (W3C PROV)
  8. Analyst review approval

    Check · Analyst · 1 day
    Map and figures reviewed · Limits and confidence written · Approve or send back
    Usage and SLO monitoring
  9. Publish as tiles and map

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.

状态

The Global Risks Index 的方法、结构和定义为预备性工作草案（2026），供审阅和评论，不供实施。在从受治理的证据截取中发布版本之前，不会出现任何数值；届时数值将附有区间、类别、来源及其更正途径。模拟器以您选择的数字运行已发布的方法，绝不显示 NXS-GRX 数值。

NXS-GRX 不是什么

NXS-GRX 是研究和风险分析信息。它不是信用评级或 ESG 评级，不使用任何评级尺度；它不是金融工具的基准，不是官方统计，不是紧急警报或官方分类，也不是建议。不得用于评估自然人。风险等级是已发布尺度上的区间，绝不是对国家或个人的排名。

机构与来源

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.

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.
