Learning about #OverpassUltra @dschep on the second day of #MappingUSA. Excited!
Ultra

A web based tool for making MapLibre GL maps with data from sources such as Overpass, GeoJSON, GPX, KML, TCX, etc

We know how exciting it is that we can make heatmaps with #OverpassUltra (cause it uses #MapLibre).

And now I realised you can make A GLOBE!

put this at the start of your style and GO GLOBULAR!

projection:
type: "globe"

Thanks @trailstash!

#TIL about this awesome interactive tool to explore toponyms in #GreatBritain called Grep Britain. 🇬🇧

(And for anything more complex and worldwide, there’s #OverpassAPI via #OverpassTurbo or #OverpassUltra using #OpenStreetMap data.)

Grep Britain

oh boy. with #postpass & #OverpassUltra I can generate heatmaps directly from OSM data.

Here's a heatmap of `place` tag's with this query

```
---
type: postpass
style:
layers:
- type: heatmap
heatmap-radius: 20
heatmap-weight: ["get", "count"]
heatmap-intensity: 0.0001
---

select count(*), geom from (
select ST_SnapToGrid(geom, 0.1) as geom from postpass_point where tags?'place' AND geom && ST_MakeEnvelope(-26, 33, 52, 72, 4326)) t group by geom
```
#OpenStreetMap

Places in the world where the blood sport, cockfighting are popular.

Well, at least those mapped in #OpenStreetMap, as queried using #OverpassUltra

Das wird eine lustige Liste, nachdem ich ein bisschen sortiert und ausgewertet habe … Habe gerade schon mal ein paar Stichproben gezogen.

Demnächst mehr.

#OpenStreetMap

I'm giving a workshop about #OpenStreetMap's Overpass query language on Saturday evening at #gpn23

It's a very powerful and useful tool, allowing for things such as custom queries, maps, statiscs, OSINT, or finding mistakes in OSM's data.

Unfortunately it's not the most intuitive thing, but we'll get you there during the workshop.

There are limited seats available and registration is mandatory: https://pretix.entropia.de/entropia/gpn23-workshops/89/

By popular demand, here's a map showing the Netto Marken-Discount / Netto distribution within Germany.

Was bored on my way to #eh22 and made a map showing the ALDI Nord / ALDI Süd distribution within Germany using Overpass-Ultra and #OpenStreetMap data.
