Natural Earth
World countries, capitals/cities points, lakes, rivers, admin-1 lines, US states, and the Russia outline are derived from Natural Earth (public domain), and shipped here as local SVG maps and quiz data.
Flags
Country and US state flag SVGs from flagcdn.com / Flagpedia (Wikimedia Commons-based vectors), included in this site. Individual flags may carry their own Commons license terms.
Sweden - landskap
- Province boundaries: perliedman/svenska-landskap (CC0).
- Coats of arms (vapen): Wikimedia Commons SVGs (per-file licenses; Swedish heraldic rules may still limit how arms are used).
- Provincial animals and flowers: concept lists from WWF Sverige and Wikipedia (province flowers). Photos come from Wikimedia Commons (searched by species); thanks to the Commons contributors who shared them.
Sweden - kommuner
- Municipality polygons: okfse/sweden-geojson (reuse offered by that project; upstream Swedish open data).
- Population figures in item text: Statistics Sweden (SCB) via their open data APIs.
- Lakes on the map: Natural Earth (above).
Brazil
-
State and region practice maps are SVG derived from IBGE-style state
boundaries (GeoJSON in this project carries
codigo_ibgand Carto-style export fields from a 2015 open dump). - Phone-code (DDD) practice maps are SVG from a 67-area DDD polygon set kept with this project; the original publisher of that polygon file is still being traced.
Philippines
- Region and province boundaries: faeldon/philippines-json-maps by James Faeldon (MIT).
- Province study list adapted from a Learnable Meta map (author όλδօ).
- Motorcycle plate strip images from plonkit.net / Philippines guide (template licenceplates.png), used with Plonk It’s stated condition that guide resources may be reused when Plonk It is explicitly credited. Colour-strip rules also follow Philippine motorcycle plate regulations (RA 11235 IRR).
Indonesia
- Province / kabupaten geometry: mashadinoor/Indonesia-Geojson-2026 (MIT; BIG-derived data - see that repo).
- Regency codes/names: edwardsamuel/Wilayah-Administratif-Indonesia (BPS-style CSV).
