This independently supplied geometry database contains only the two original public Crimea (UA-43) and Sevastopol (UA-40) features, selected from the pinned upstream dataset. The selected geometry database is made available under ODbL 1.0. The machine-readable database is ukraine-crimea-sevastopol.geojson; provenance accompanies it. No sanctions records, private research, workbook contents, application source or business information are included in these downloads.

Administrative boundaries represent 2017 data, updated/built in 2023; they do not depict current control lines. Application code selects display colors separately and does not insert sanctions attributes into the geometry database.
