Mexico GeoJSON — States and Municipalities (2025)

This dataset provides Mexico’s 2025 political–administrative boundaries at the state and municipal levels, converted from authoritative CONABIO shapefiles into GeoJSON and delivered in both full-resolution and topology-preserving simplified forms.All processing was performed using GeoPandas to ensure cartographic integrity, metric-based generalization, and compatibility with modern web-mapping and GIS workflows.Two 8K reference maps are included, showing national coverage at the state and municipal levels.Processing MethodOriginal CONABIO shapefiles were loaded into GeoPandas.Data were re-projected from EPSG:4326 to EPSG:3857 to enable meter-based geometric operations.Topology-preserving simplification (Douglas–Peucker) was applied:States: 100 m toleranceMunicipalities: 15 m toleranceLayers were re-projected back to EPSG:4326 (WGS84).All layers were exported to GeoJSON.The preserve_topology=True option ensures that polygon adjacency, shared borders, and spatial validity are maintained, preventing gaps, overlaps, and self-intersections.Included Filesstates_full.geojson — Original state geometries in GeoJSON (no simplification)states_simple.geojson — State boundaries simplified at 100 m, topology preservedmunicipalities_full.geojson — Original municipal geometries in GeoJSONmunicipalities_simple.geojson — Municipal boundaries simplified at 15 m, topology preservedstates.png — 8K reference map of state boundariesmunicipalities.png — 8K reference map of municipal boundariesUse CasesFull layers: spatial analysis, legal or administrative mapping, high-precision cartographySimplified layers: web maps, dashboards, interactive GIS, and high-performance renderingData SourceCONABIO — Comisión Nacional para el Conocimiento y Uso de la Biodiversidadhttp://www.conabio.gob.mx/informacion/gis/
