Maps and layers

The network on a live OpenStreetMap globe, with open-data layers for the home region. Each outside layer comes from a registered source and is drawn only after the owner approves it.

Before you begin IDCDC is a peer-to-peer network. It is not a university and acts for no government, party, corporation or faith body.

Outside sources keep their own licences. A listing or a link is not an endorsement.

How this page handles evidence

Every figure carries its measure, year, source and label. Unknown is shown as unknown.

Verified
A label: the item matches its primary record, such as the official table or the Crossref entry.
Secondary source
A label: the figure comes from a reliable report about the source, not from the source itself.
To verify
A label: the item is listed as found and still needs checking against its source.

01The network and its layers

Turn layers on and off in the panel. Switch between the globe and the flat map. City points open their pages.

The map needs JavaScript. The layers it shows are listed beside it.

Layers

  • Cells of the H3 grid at resolution 2, shaded by how many city pages they hold. A count of pages, not of people.

  • Earthquakes of magnitude 4.5 or more in the last 30 days, in a box around Iran.

  • First-level provinces of the home countries, each with the licence of its source.

  • Awaiting licence review

    Urban centres from the GHSL database, as context for the city pages.

  • Awaiting licence review

    Gridded population density of the home countries, as context. Never a count of the community.
