Does anyone know a way to get good GeoJSON for neighborhoods? Like the city of Austin publishes some but they’re related to the way the city is administered not the actual neighborhoods

For #30DayMapChallenge day 5: Earth, I wasn't particularly motivated until I remembered that one guy in Auckland (AoNZ will understand what I mean) so learned to process geojson- Earthquakes (+) over 3.5 Magnitude, south of -38.8 and where and how strongly they were felt. #rstats code in alt text

GeoArrow is undoubtedly a superior format to GeoJSON, yet GeoJSON remains the dominant standard in web browsers. I'm hoping we'll reach a point where using GeoArrow is just as easy and seamless as using GeoJSON. I hope my talk helps to figure out what's still missing in the ecosystem.

The fact that I have decided I am dissatisfied with a good chunk of the geoJSON from the API, I am manually replacing some of it, and this is why my childhood report cards always said I get so into details that I lose sight of the big picture...

If you ever need someone who has now become an expert in weird geoJSON assemblages to create polygons for disputed territories or historical geographical entities, it me.

Ahhhh the soothing feeling of hiding in the Studio (trying to adjust to our rebrand from two separate labs to the Creative and Critical Data Studio) and spending a morning adding VIAF and Wikidata identifiers and GeoJSON to a data repo.

idk if the alt text is working so here the nerdy details are also in the alt text of this picture of my mom's cat butterscotch
Animation of a zoom in from about 100 parsecs away to Earth, made 100% in Blender using Eevee render engine w/ render times below 7 secs on gtx1050 graphics card. Data used from NASA SVS website for most textures, including a cloud simulation! Also from the Hipparcos mission of the ESA, someone made a csv file of the stars with colors, distances, and magnitudes. Blender has issues when dealing with large and small scenes, and float point limitations (computers can only do so much) so the distances are not accurate, but I tried my best. I think I can achieve near perfect accuracy in a few weeks of messing around with linking cameras at diff scales. I can also use geojson data here. Looking at plate techtonics data and milky way data, but that might require help. I can get data in and with great accuracy, but I'm doing all this on a potato, and with only 20 GB of free storage space at a time, in eevee, so I may have to table this again (for now). Hope someone thinks this is cool!

In terms of best practice, what's the consensus on objects as properties of GeoJSON features?

I further filter from a geographical area to avoid false positives. Red= filtered, purple= pre-filter. (Diff. timespan, dots illustrative.) There will be some false positives left. The geojson is an estimate by me, based on a certain look that I cant quantify but is visible?

This makes me inordinately happy every time I see it. :)

We/I try to use semantic versioning but a major bump feels so... major to me! Love seeing that it doesn't have to be!

4/8 Ensuite, pour afficher les établissements sur une carte, j’ai croisé ces données avec l’annuaire des établissements. Ce dernier donne directement les coordonnées GPS grâce à un code unique. 🌍📌

Tout ça combiné = un gros fichier GeoJSON pour ma carte. 🗂️✨

Most user-friendly: @Datawrapper.be has tons of predefined maps all around the world. And you can upload your own GeoJSON file if that's not enough. One of the students in my workshops used this to build an interactive map of a conference hall, with booths and everything!

A map of Belgium, each municipality has a color brightness based on the number of companies per 1000 inhabitants. Highest values are in the North and West of the country. Municipalities are shaded for regions where regional aid is available to support economic development, mainly in the central and south-east part of the country.

Question for the GIS/GTFS crew:

Say I have a collection of route shapefiles I've converted to GeoJSON and layered onto a custom basemap. Now say I want to pick up this layer and place it on top of another city to create a visual comparison of two service areas. What tools can do this and how?

Working on a mapping project to show Berkeley's retail & commercial vacancies.

It uses openstreetmap data extracted to geojson.
You can try it here. Just press filter.

And I generate the JSON file with whatever tool I want (Kotlin so far) and the map tool is basically a viewer that I plug in the JSON data file + precincts GeoJSON file in and does the bare minimum of what I need.
