Imagery catalogues through STAC
Satellite and aerial products are indexed as STAC items with footprint, time, sensor and processing level, so analysts query by place and date and analysis runs next to the archive.

Informasi geospasial sistem give every record a place: hazard grids, asset registers, boundaries and imagery brought into one frame. In this field they also carry the sharpest disclosure risks, so the work runs from coordinate reference and catalogue through to a recorded public-safe release decision.
Informasi geospasial sistem capture, store, analyse and present location-referenced data. They provide the common spatial frame for combining hazard, exposure and vulnerability information. In data and compute and methods and modelling, geospatial analysis identifies where hazards overlap critical assets and vulnerable populations. It supports location-based planning across infrastructure, health and finance. The canonical description is on STEM Commons.
Satellite and aerial products are indexed as STAC items with footprint, time, sensor and processing level, so analysts query by place and date and analysis runs next to the archive.
Hazard layers are intersected with buildings, population grids and networks on a common equal-area grid, with the aggregation unit and denominators stated beside every count.
Before publication, sensitive layers are generalised, small counts are suppressed and combinations with other public data are reviewed; the release record names the person who decided.
Population density, land cover and night lights over North America, from NASA GIBS. Each layer carries its own date.

Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.
| Pemeriksaan | Cara pelaksanaannya |
|---|---|
| Reference system check | Every layer’s horizontal and vertical reference is declared, and transformations use EPSG definitions |
| Positional accuracy | Layers are compared with surveyed control points and the error is published with the layer |
| Topology validation | Gaps, overlaps and invalid geometries are detected before any overlay |
| Disclosure review | Published resolution and layer combinations are checked so no facility or household can be singled out |
Errors in projection, scale and data currency propagate through analysis. Aggregation to administrative units can mask local variation.
A Jejak bahaya takes out co-located assets in every layer; fragmentation, dependency between layers and overload of the survivors then spread the failure. The 3D view separates the layers by depth. Teaching model with stated illustrative values, not a prediction. The map on this page shows North America; the model itself is not tied to a place.

Di seluruh enam pilar, dipimpin oleh Nexus Consortium
Disusun dari profil bidang Nexus Standards profil area Infrastruktur kritis dan entitas kritis: bahaya yang disebutkannya, sistem dan sektor yang menanggung kerugian, kendali yang meredamnya, dan data yang mengamatinya. Pilih komponen, tentukan bahaya pemicu, dan telusuri kaskade langkah demi langkah. Tampilan Peta menempatkan proses pada contoh geografi dengan data terbuka. Setiap bobot keterkaitan adalah asumsi yang dinyatakan dan dapat Anda ubah. Model pengajaran, bukan prakiraan, penilaian, atau sertifikasi.
