The registry
Every concept, connector, deployment and source TGIS knows about, read from the database. Read at 22 October 2026 at 23:21 UTC; the page refreshes at most once an hour.
Why it is shaped this way is on the model. How one question uses it is on how this works.

The chain
A question is matched to concepts. A concept is filed against sources. A reachable source lives on an endpoint, and a connector reads that endpoint. A source with no way in still answers, with who holds it.
Concepts
The shared vocabulary every source is filed under. A person writes and reviews each one; a run may never add one. Hover a concept for its definition; each dot is one source filed under it.

Concepts with nothing reachable
NO2 tropospheric column density, Travel time to school, Night-time light, Surface reflectance, Committed or proposed scheme, Transport greenhouse gas emissions, Vehicle fuel economy. A question about any of these ends in a named holder or a live search of the portals, never in a substituted figure.
Connectors
Data arrives through a small number of kinds of door. Each kind has one connector, a piece of code that speaks it. 67 sources are reachable through 11 connectors today.

- WorldPop R2025A gridded population, Ethiopia
- WorldPop unconstrained population, R2024B
Research archives
1 source
Datasets published alongside scientific papers, read tile by tile.
- Global Flood Susceptibility Map (GFSM v1)
Humanitarian statistics
1 source

- OCHA HAPI baseline population, Ethiopia
parquet

- Ookla Speedtest fixed and mobile performance
Air quality monitors
1 source
A global aggregator of ground monitoring stations and their readings.
- OpenAQ v3 air quality measurements
Coverage grows with doors, not with datasets. A second open data portal is one more row, not new code: the connector that reads the Humanitarian Data Exchange reads Transport Data Commons too.
Deployments
An endpoint is one deployment of one protocol: HDX's CKAN, the OECD's SDMX. Whether it is searched during a question is measured, not set: a catalogue too slow or too large to search per question is harvested on a schedule instead.

The bar is the sources each deployment holds: solid when a connector reads them, dashed when a harvest has only listed them. A deployment with none is one the registry can search but no run has drawn from yet.
Sources
One row per dataset. A reachable source is fetched live; a named gap is a dataset someone holds and nobody can fetch, kept so the answer can say who to ask; a candidate was listed by a harvest and earns its connector the first time a run uses it.

Evidence and subjects
Every figure inherits the kind of evidence of the source under it, and the answer shows it. A planner accountable for a number treats an official count, an instrument reading and a model's estimate differently.
- Official statistic 17Published by a government body as its figure
- Instrument reading 19A satellite or a monitor measured it
- Modelled estimate 34Computed from other data by a model
- Derived product 30Built from other sources, such as an OpenStreetMap export
- Survey 1People were asked
- Stated intention 4A plan or a target, not a measurement
- Not yet checked 32Harvested from a catalogue and not yet read by a person
Sources by subject
A source can sit under more than one subject. Transport has the most gaps because most of what a city transport office holds (ridership, travel surveys, traffic counts, the road hierarchy) is supplied on request only.
Places
The place spine: administrative units with the codes different publishers use for them. A run resolves a place name here before it looks for any data, and no city is written into the code.

Observed
What calling the sources has recorded. A source row holds what someone claimed about it; these hold what happened when it was called.
821
calls, each with what came back
199
coverage measurements over an area
30
disagreements between sources, written down
37
fetched files kept, so nobody pays twice
The warm set
Sources whose calls measured slow (over five seconds at the 95th percentile) or heavy (over 20 MB), so their files are fetched ahead of a question. Computed from the calls; a source falls out on its own when its provider speeds up.
