A durable record of which external data ecosystems Habitability has explored, what they can measure, where they fit, and why they were admitted, held or rejected. Exploration does not imply scientific validation.

Primary candidate for harmonised socioeconomic and urban indicators.
Geography: city · FUA · 2005/2015/2025 fit: REVIEW
Domains: demography · economy · labour · health · living_conditions · transport · environment
Revisit when: Complete variable-level coverage and licence audit · Last reviewed: 2026-09-20
Treat as primary candidate source, not only benchmark.
Geography: city/FUA · municipality · region · 2005/2015/2025 fit: REVIEW
Domains: demography · economy · climate · environment · transport · housing
Revisit when: Complete indicator-level time-series and reuse audit · Last reviewed: 2026-09-20
High-priority candidate backbone; much broader than GHS-POP.
Geography: urban_centre · 2005/2015/2025 fit: REVIEW
Domains: population · built_environment · land · climate · environment · infrastructure · urban_form
Revisit when: Map UCDB attributes to Habitability constructs and FUA crosswalk · Last reviewed: 2026-09-20
Derived-first candidate for heat; evaluate before any further raw ERA5 pipeline.
Geography: grid · European derived views · 2005/2015/2025 fit: LIKELY
Domains: heat · cold · precipitation · drought · fire · climate_hazards
Revisit when: Audit exact historical products, spatial resolution and reusable downloads · Last reviewed: 2026-09-20
H05 experience shows semantics must be checked at artifact level.
Geography: various · city/commuting-zone for selected products · 2005/2015/2025 fit: REVIEW
Domains: air_quality · climate · land · green_infrastructure · adaptation · hazards
Revisit when: Dataset-level inventory and geography/time audit · Last reviewed: 2026-09-20
Potential ready-made land-use trajectory; never relabel vintages as exact 2005/2015/2025.
Geography: FUA · 2005/2015/2025 fit: NEAREST_VINTAGE_REVIEW
Domains: land_use · green_space · built_environment
Revisit when: Evaluate explicit 2006/2012/2018/2021 nearest-vintage rule · Last reviewed: 2026-09-20
Scientifically useful; must not silently become production geometry.
Geography: city · FUA · 2005/2015/2025 fit: N/A
Domains: geometry
Why not used: Commercial reuse/redistribution constraints require explicit clearance or replacement.
Revisit when: Exact rights clearance or commercially usable harmonised FUA alternative · Last reviewed: 2026-09-20
Every source remains addressable by a stable ID. Holds and rejections preserve their rationale and a revisit trigger, so future research can resume from prior evidence rather than repeat the same exploration.
This Observatory is a research and build artifact. ADMIT/REVIEW/HOLD/REJECT are source-selection states, not Research/Validated/Published evidence states and not publication approval.
