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 sample 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/

Acabo de actualizar los #GeoJSON de la división política estatal y municipal de #México (2025), con los cambios administrativos más recientes.

Útiles para mapas, análisis… o para dejar de usar ese shapefile misterioso que alguien te pasó en 2012.

Okay, there was supposed to be something about #architecture, but today I was absorbed by the #GeoJSON editor. 🗺️

The most difficult thing about programming? Resisting the urge to implement new ideas! 😅

I love #code! 👨‍💻

Interactive map of Warsaw with blue polygon overlays highlighting multiple service or analysis zones and a layers panel showing 34 layers.

Under a recent post, someone asked if I really need such an extensive #architecture. 🤔

While I developed my approach more for sport, the project itself is quite elaborate. In fact, it's time to return to my #GeoJSON editor, which will play a major role in the data layer. 🗺️

GitHub - opendatalab-de/geojson-jackson: GeoJson POJOs for Jackson - serialize and deserialize objects with ease GeoJson POJOs for Jackson - serialize and deserialize objects with ease - opendatalab-de/geojson-jackson

I still need to either fork (and maintain 🙁) or inline geojson-jackson. Thankfully just a small #GeoJSON library. That was my only significant breaking point. Unfortunately github.com/opendatalab-... looks unmaintained. The fun of #OpenSource 🙂.

I want to finish the #ZarazJade refactor before the end of the year. It will include several additional features. 🚂

This means I will also bring back another project of mine! #GeoJSON is key to a good transit app! 🗺️

I love what I do! I end the year with a bang! 💥

Question: Are there freely available #GeoJSON files out there for the boundaries of the provinces/states of various Central European nations?

I need them individually, i.e. one for "Bavaria" one for "Tyrol", and so forth.

Using CDFs, can a single Data Provider return several layers? Hi, I have read through the docs and the Samples Github repo, but I have not yet found clarity regarding multi-layer CDFs. At developer stage the console is pretty clear regarding the routes:debug: ROUTE | [GET, POST] | /test-layers/rest/services/FeatureServer debug: ROUTE | [GET, POST] | /test-laye...

The official documentation states clearly that the exposed table does not cover all:The table below describes some of the key metadata properties:

I've been looking at assorted ways how to (a) replace my German Folklore Map with something #OpenStreetMap -based (b) making it filterable based on narrative elements (such as "dragon", "treasure", and so forth), and (c) integrating it into my new #Mediawiki wiki.

Bruh what's with formats being made that don't focus on streaming as a baseline requirement? Lookin at you #GeoJSON!

I get you "can" do streamed parsing of JSON, but it's just so much more efficient to do something like ND-JSON at the very least.

#GetCoordinatesOnline is in a very early stage of development. But we already have important functionality. We can place several points on the map, get their coordinates and export them to #GeoJSON.
