HERA · Human Entity Reference Atlas · Phase 2 Live Ingestion

Every country.
Every admin level.
Zero data loss.

HERA — the Human Entity Reference Atlas — discovers, normalizes, and packages public census and human-geography data for every country on Earth. Aligned to DGIWG SEL and CCL, cross-walked to Overture Maps via stable GERS IDs. Official sources first. Every field preserved.

Why HERA

Built for the Complexity of Human Geography Data

Every national statistics office publishes differently — APIs, PDFs, web tables, bulk downloads, restricted access. HERA handles all of it, and preserves every field along the way.

Official sources first

Primary data pulled directly from NSOs — Census Bureau, StatCan, ABS, ONS, IBGE, INEGI, INSEE, GUS, e-Stat, and more. Secondary sources (World Bank, WorldPop, DHS, MICS, HDX) supplement where needed.

Every admin level

If a country publishes at six admin levels, we create six tables — not one. 56 countries ingested at admin depth 3 or deeper: tract, ward, gmina, neighborhood.

Zero data loss

Every field from every source is captured in the DatasetFieldInventory. If the DGIWG schema can't hold a field, an extension table does. Nothing is silently dropped.

DGIWG + Overture aligned

Spatial/demographic data maps to DGIWG SEL; cultural/linguistic data to CCL. Admin boundaries and places are built to cross-walk to Overture Maps via stable GERS IDs (US counties crosswalked today, expanding with GERS coverage). ISO 19115 XML ships with every package.

Multi-format export

CSV, Parquet, GeoJSON, Excel, and ISO 19115 metadata XML — every country package ships in every format, with provenance, QA reports, and licensing baked in.

Site Selection engine

3,311 US counties scored for 15 business types: hotels, casinos, dispensaries, restaurants, warehouses, and more. Weighted by tax environment, regulatory status, and pending legislation.

Themes we collect

Every dimension of human geography.

From population and housing to religion, language, migration, and health — HERA captures every thematic layer that matters for defense, development, and commercial decisions.

HERA × Overture Maps

For everyone who builds on or buys Overture data

The human-context layer for every Overture division.

Whether you contribute to Overture Maps, build products on top of it, or license its data downstream, you get places, buildings, and administrative divisions — but no context about the people who live inside them. HERA is that context layer. We pull census, demographic, cultural, and linguistic data directly from national statistics offices across 283 live countries (with 283 configured and ingesting), built to join to Overture via stable GERS (Global Entity Reference System) identifiers — the persistent ULIDs Overture assigns to every division. US counties are GERS-crosswalked today; the join key is designed to extend to every admin unit as GERS coverage grows.

If you're an Overture contributor, HERA is the enrichment layer your customers keep asking for. If you resell or redistribute Overture data, HERA is the value-add that lets you charge a premium. If you're building products on Overture — mapping, LBS, geo-AI, retail siting, logistics, risk — HERA is the fastest way to turn empty polygons into decision-ready rows. Building the 283-country ingestion pipeline in-house takes years of engineering across API, bulk, scrape, and PDF extraction paths. We've built the hard part. Plug us in.

Hook #1 · Census & Demographics

Official NSO data for every Overture division.

Population, age, sex, households, housing, income, employment, education — pulled directly from US Census, StatCan, ABS, ONS, IBGE, INSEE, INEGI, GUS, e-Stat, and 30+ more. Joined to Overture division GERS IDs at every admin level the country publishes.

Hook #2 · CCL (Overture has nothing for this)

Religion, language, ethnicity, migration layers.

Overture stops at the physical world. HERA's CCL layer adds the cultural and linguistic dimensions: religious affiliation, 11,161 languages with genealogy and endangerment, ethnic groups (D-PLACE / EPR), refugee/IDP flows, and cultural values (WVS / regional barometers). A category Overture simply doesn't carry.

Countries crosswalked

Two honest numbers: 95.2% of all the admin units HERA holds carry a stable Overture GERS ID today; and where Overture models a division at our granularity, HERA matches 95.2% of them. The gap is where Overture models no division at that depth (e.g. Brazil's municipalities) — we hold the authoritative, commercial-safe boundaries for those and are contributing them back to the GERS registry.
