FAQ

Common questions

Most questions that hit the inbox cluster around the same handful of topics. This page gathers them in one place. Read top to bottom, or jump straight to the section that matches your situation.

Pins, shortlist, and the difference between them

A pin is a marker at a specific coordinate, usually carrying a URL: a real-estate listing or a personal landmark. A shortlist entry sits at the location level (city, town, village) and pulls the whole metric profile through compare and visit planner. Pins are object-level; shortlist is location-level. Use both. They do different jobs.

Sync and devices

Shortlists sync once you sign in. Without an account, they live in the browser only. Pins and annotations always require an account — they live on the server. Filters and compare selections live in URLs, so sharing them is as easy as sending a link.

Offline use

On first load for a country, the geometry and metric data are cached. After that, repeat visits work fast even on a poor connection. True offline — no connectivity at all — is partially supported: cached data is available, but new edits queue locally and replay once you are back online.

Sharing your work

  • Filters — share the URL. The hash captures filter state.
  • Compare table — share the URL. It encodes the selected locations.
  • Visit planner — share the Google Maps link or the GPX file.
  • Pins, shortlist, annotations — not directly shareable today. Workaround: open the relevant compare or visit URL — it carries the data without exposing the account.

When something looks wrong

Data errors flow through the feedback button: a number that does not match the source you trust, a POI dot that should not be there or is missing, a tax rate that changed last month. Each report is reviewed in batch, and updates ship in the next data refresh cycle.

Behavioural issues are different: the map will not load, a filter does nothing, a sync seems stuck. Most of them clear with a hard reload (Cmd-Shift-R on macOS, Ctrl-F5 on Windows). If they do not, send the URL plus a short description through the feedback button and we will dig in.

How fresh is the data

Every metric in the details panel carries a verified date. Climate data refreshes annually; tax rates around policy changes; infrastructure (hospitals, stations, airports) on a quarterly cadence as OpenStreetMap is ingested. Where freshness matters, the date is the source of truth, not the polished look of the metric.

Frequently asked

My country is not in the supported list yet. When will it be?

Coverage expands as research finishes. The Atlas country catalogue shows the current state. A country in the catalogue with a thin data layer is on the roadmap; a country missing entirely is not yet planned.

Can I use the map for a paid client project?

Yes. The data and the interface are usable for any non-redistribution purpose. If you plan to use it as a consultant, the partner programme has dedicated tooling for that case.

How do I report a data error?

The feedback button (bottom-right on most pages) opens a small form. Include the metric, the location, and the source you believe is correct. Updates ship in the next data refresh cycle.

Is the source code open?

The product is closed-source today. The methodology behind the data — sources, refresh cadence, calculation rules — is open, documented in the Atlas and on the Methodology page linked from the homepage.
