Tijuana city guide — sources and map provenance Reviewed 18 October 2026 MAPS The fourteen polygons are original approximate learning areas, generated from named neighborhood and visitor-corridor anchors by scripts/build-tijuana-map.mjs. They are a schematic partition of a limited visitor corridor, not official delegacion or colonia boundaries, the municipal limit, a navigational map or an assessment of local security. The labels deliberately mix neighborhoods with broader learning areas, including the airport corridor and the eastern Parque Morelos cluster. The whole municipality is not shown. The original schematic polygon geometry is released under CC0 1.0: https://creativecommons.org/publicdomain/zero/1.0/ Sight pins identify selected places rather than guaranteed public entrances. Coordinates were checked against cultural venue records, Wikipedia/Wikidata, Wikivoyage listings and OpenStreetMap data. Caesar's, Mercado Hidalgo, the Casa de la Cultura, the former municipal palace, Pasaje Rodriguez, the cathedral, Plaza Santa Cecilia, El Trompo and Parque Morelos received individual location checks. In particular, the similarly named Parque Morelos in Guadalajara is not the Tijuana park.
