Administrative boundaries for the 18 mainland districts (distritos) of Portugal. Primary official source (Direção-Geral do Território / dgterritorio.gov.pt, all subdomains) is network-unreachable from this vantage (TCP connect timeout across geo2/ogcapi/snig/www subdomains, reproducible) — sourced instead from Huwise's 'georef-portugal-distrito' geographical repository (OpenDataSoft), which explicitly attributes Direção-Geral do Território as contributor, vintage 2024, filtered to dis_type='district' to exclude the 2 autonomous regions (Açores, Madeira).

Federal Electoral Districts of the Canada, 2023. PUBLISHER/SCHEMA EXCEPTION — read before processing. Publisher is ELECTIONS CANADA (hosted by NRCan), not StatCan; licence is Open Government Licence – Canada (open.canada.ca record 18bf3ea7-1940-46ec-af52-9ba3f77ed708, license_id ca-ogl-lgo): copy, modify, publish, distribute. Elections Canada specifies NO attribution string, so the OGL fallback applies. CHOSEN OVER StatCan's lfed000b21a_e.zip (which IS live, 206) because that file is the OBSOLETE 2013 Representation Order (338 seats); the 2023 Rep Order (343, proclaimed 2023-09-22) is current and was used for the 2025 general election, so real joins will be against 343. SCHEMA BREAK: fields are FED_NUM (LONG), ED_NAMEE(100), ED_NAMEF(100), REP_ORDER(4) — there is NO FEDUID, NO FEDNAME, and NO DGUID, so this type does NOT fit the CA-DGUID code_scheme and anything assuming StatCan field names will break. FED_NUM is an integer, not a zero-padded string. CRS CONFLICT UNRESOLVED: the ArcGIS REST layer reports EPSG:3978, but the technical guide's parameters (false easting 6200000, northing 3000000, central meridian -91°52', SP 49/77) match EPSG:3347 instead — read the .prj at convert, do not assume. Single geometry variant, no carto/digital split; 9,388,965 bytes (Last-Modified 2024-12-17), already generalised. Verified 206 application/zip.
