Administrative areas

Pinned source: https://github.com/wmgeolab/geoBoundaries/tree/90a1d52/releaseData/gbOpen/BIH/ADM1
Source credited by geoBoundaries: Wikimedia Commons; public domain; represents 2013.
Metadata: /data/bosnia-boundaries-source-metadata.json
The source contains the Federation of Bosnia and Herzegovina, Republika Srpska
and Brčko District. Brčko is a self-governing district, not a third entity.
The source's trailing asterisks are removed from its ISO-like lookup codes.
Federation cantons and municipalities are not shown. These are administrative
reference boundaries, not ethnic homelands or a current boundary survey.

Rivers

Named river ways are merged and all river sources are clipped to the union of
the three administrative areas with a 0.02-degree margin. Very small details
are simplified by 0.00008 degrees. Named OSM ways can contain gaps. Rivers and
tributaries are selected for learning: this is not a complete drainage network,
a navigation chart, a control map or an indication of safe outdoor access.

Cities and towns
Curated coordinates from English Wikipedia coordinate records, fetched
19 October 2026, with expected entity/district checked against the geometry.
Urban reference points are not municipal boundaries. Article titles and the
retained coordinates are in scripts/bosnia-map-places.json.

Reproduction
python3 scripts/build-bosnia-maps.py (Shapely 2).
The builder reads scripts/bosnia-map-source.geojson and
scripts/bosnia-map-places.json without network access. Selected source geometry,
metadata and attribution are retained alongside the resulting maps.
