OCHA COD-AB Viet Nam ADM1, sourced from the General Statistics Office of Viet Nam (GSO). 63 provinces and centrally-governed cities — the division in force from 2020-01-03 until Viet Nam's 2025 administrative reform (effective 2025-07-01) merged them into 34 units. Published to serve data keyed to the pre-reform division, which covers essentially all Vietnamese provincial statistics up to 2024. Source fields DATE=2019-10-01, VALIDON=2020-01-03, VALIDTO=null. Bytes retrieved from the fieldmaps.io COD mirror (https://data.fieldmaps.io/cod/originals/vnm.shp.zip, src_name 'Government of Viet Nam', src_lic CC BY-IGO, src_url the canonical HDX page) because the HDX COD-AB resource has been replaced in place by version 02, the post-reform 34-unit set; source zip sha256 7bd79710. Keep-list ADM1_EN/ADM1_VI/ADM1_PCODE; ADM0_* dropped as constant, DATE/VALIDON/VALIDTO dropped as metadata. One RFC7946 writer artefact (Quang Ninh VN225, GeometryCollection{MultiPolygon, 2-point LineString}) coerced to MultiPolygon per decision 0020 — source geometry was ST_IsValid=1 and plain ogr2ogr produced zero collections; total area preserved to 2e-10 relative. Extent reaches lon 117.8/lat 7.18 because the set includes the offshore island districts as the publisher represents them: Hoang Sa (Paracels) under Da Nang city, Truong Sa (Spratlys) under Khanh Hoa — disputed-sovereignty areas carried exactly as published, not edited. Five-view inspection clean, shoreline-clipped variant (archipelagos render as discrete islands). Produce fixes: multi-normalised only. Resolver miss ms_995cba076f7746109dbeef0787d46c79, join 63/63 at 100%.

OPERATOR NOTE. Source: OCHA COD-AB Ethiopia v04 (eth_admin_boundaries.shp.zip, layer eth_admin3), sha256 b5456da9346a448bbf135896e03c9a82a7c1fa2e13a6f11a8e281efe4e4a49ac, retrieved 2026-10-29. Upstream is the Ethiopian government: CSA (Central Statistics Agency) + regional BoFEDs; OCHA methodology states 'Shp file received from CSA and government', P-codes adapted to OCHA standards. Hierarchy cross-checks against the publisher's own declaration: 15 adm1 / 107 adm2 / 1148 adm3. Convert kept names+identifiers only (adm3_name, adm3_pcode, adm3_alt_n, adm3_ref_n, adm2_name, adm2_pcode, adm1_name, adm1_pcode); area_sqkm, center_lat/lon, all-null alt-language columns and constant adm0/version columns dropped. Reconciliation 1148 source -> 1148 converted -> 1148 published, 0 dropped, 0 filtered. 2215 nulls all attributed to the two optional alt-name columns (adm3_alt_n 1090, adm3_ref_n 1125); zero nulls in every identifier and canonical-name column. Produce fixes: crs-reproject-verified + multi-normalised only, no geometry repair. Five-view inspection clean, full resolution, no simplification. Published by the boundary-miss nightly pass for bucket admin:ethiopia:woreda:: ; the five retained acceptance files did NOT join at woreda level (32.2% exact, 29/90, measured by verify_boundary) because that project spreadsheet uses non-standard transliterations - the misses stay open.
