Urban exposure databases
Building footprints, land use and population are combined into exposure databases that risk, service and planning analyses share.
GCRI · 城市与建成环境
地理空间信息 系统 hold the city’s map: land use, buildings, networks, services and hazards. In this field they support planning, exposure analysis, service gap mapping and community mapping, with residents involved and data protected.
地理空间信息 系统 capture, store, analyse and present location-referenced data. They provide the common spatial frame for combining hazard, exposure and vulnerability information. In cities and built environment, 关键基础设施 and society and human development, 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.
Building footprints, land use and population are combined into exposure databases that risk, service and planning analyses share.
Residents of informal settlements map streets, services and hazards with open tools, keeping control over how their data are used.
Hazard maps are overlaid on zoning and growth areas to show where planned development would increase exposure.

| 数据 | 角色 | 标签 |
|---|---|---|
| OpenStreetMap | Streets and buildings | 观测 |
| Open machine-learned building footprints | Building outlines | 估算 |
| Global Human Settlement Layer | Built-up area and population | 估算 |
| Municipal zoning and cadastre | Planning layers | 已发布统计 |
团队遵循该方法时会使用的界面:其指标、状态与决策。名称为示例,数值仅作示意。
Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.
| 核查 | 如何开展 |
|---|---|
| Completeness assessment | Building and street coverage is compared with imagery or field samples |
| Consent and data protection | Community data are used only as agreed with residents |
| Positional accuracy | Layers are checked against reference points |
Errors in projection, scale and data currency propagate through analysis. Aggregation to administrative units can mask local variation.

The model runs on the teaching values set by the controls. To calibrate it for a place, read it against these admitted layers and series, which this page’s map can draw:
贯穿六大支柱,由 Nexus Consortium 牵头
Assembled from the Nexus Standards area profile 城市与建成环境: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.
