I have a ~ 8 GiB GeoJSON file. What's would you use to compress it? gzip is regular and fast, but not as space saving. Something installable via apt on debian

(and no cheeky answers like converting it out of geojson! 😛 I wanna know what The Cool Kids are using as compression tools now-a-days)

looking to data from a proprietary format into an open format, to be specific.

any suggestions on good ways to proceed using ?

Emphasis should be placed on the *transform* step (e.g., I can't simply convert the XML to JSON, I need to modify fields/values).

et hop, plus de 3000 bornes de recharge électriques intégrées (progressivement par zones et après vérification à la mano) dans osm grâce à mon mappeur de donnés geojson en provenance de du jeu de données datagouv vers

forge.chapril.org/tykayn/scrip

ce dépôt permet de mapper des propriétés de à partir d'une configuration en json qui va prendre et transformer les données selon des critères simples ou complexes, le tout en et .
vous pouvez déjà créer vos propres fichiers de configuration de mapping. le script npm start vous montre comment personnaliser la commande de conversion.

on peut ensuite transformer le geojson en fichier osm à utiliser dans l'éditeur avec geojsontoosm.

havez fun

PostGIS is so cool, did you know you can just make it return rows as GeoJSON?

Say you have a table with an id, location and other columns. You can `SELECT ST_AsGeoJSON(t.*) FROM thetable AS t` and it will return niceley formatted puttin all extra columns as "properties". Even the SRID of the location will be added 🤩

Given a collection of geoJSON features, adjoining polygons, is it possible to collate or collapse them to be just the outer boundaries of adjacent features? A handy library or postGIS thing?

It is always a good idea to optimise your GeoJSON files if you are going to use them on the web. Often GeoJSON files can be bloated because GIS software will output ~15 decimal places on every coordinate. That is effectively to Angstrom accuracy - atomic scales! In a big GeoJSON file, as much as 40% of the file size can be due to entirely unnecessary precision. I've made a simple tool to help optimise files at open-innovations.github.io/geo

So it seems that I can do something a bit hacky with and have event pages be able to have files sitting next to their ones, and the map will show them. I was too busy trying to make it work to ask anyone if this is what we want. Still, that's fun isn't it?

I love my code:
- translated from local to
- connects to 's RDS and S3
- makes calls
- uses and intersection

(still, for handling dataframes, R is better IMO)

Having incredible difficulty getting to read data types (shapefiles, kml); no idea how to convert area and length from a csv.

file is taking forever to generate.

Shapefile works just fine in , which makes me think it's an thing (perish the thought).

Don't know what else to try at the moment.

GitHub changed its awsome rendering of from & to Microsoft Azure Maps and now nothings works anymore due to CORS and CSP. Not even the feedback button ... not even in Edge 🙄

Or is this just me?

Great map showing lighthouses in Europe, from the Geodienst researchers of Groningen University (geodienst.xyz/): geodienst.github.io/lighthouse

Project: github.com/geodienst/lighthous
The lighthouse data is in JSON format.

Here is a view of southern Europe. Location, color, pattern and area covered are all real.

h/t @Lambo 👍 !
