Je tente ma chance : quelqu'un sait où et comment me procurer en carte géoréférencée (si possible en shapefile) des départements français en 1848 (ou en tout cas avant 1860)?
Je cherche à faire des cartes sur QGIS pour ma thèse mais je me heurte un peu aux absences de données historiques utilisables. J'ai moyennement envie de tracer des polygones moi-même...

Friends don't let friends save geodata as #shapefile 
(http://switchfromshapefile.org)
On a related note:
A friend is looking at tracing features (mostly streets and public transportation) from old city maps (Berlin, 1920-30s) with #QGIS. Does anyone have recommendations for (semi-)automated tools?
We've already tried Bunting's AI-Tool and 'Raster Tracer' https://plugins.qgis.org/plugins/raster_tracer, both with some success but not entirely satisfying...
Maybe something using #gdal?

Hey #spatial #R folks, is it possible to extract geometries from #ggplot as files? That is, the point, line, and polygon geometries in the graphs to #geopackage or #shapefile etc.
It is possible with #seaborn and #matplotlib, but that's Python not R. There's a nice and lightning fast #EdgeBundling technique in the newest ggplot, which is very promising for the #visualization of massive #mobility data.
There is also something in #HoloViews but I do not understand that library at all.
Started to build a webapp that generates random #geodata for testing and experimenting
Currently only points are supported. Export works for #GeoJSON and #Shapefile
The data generation runs fully client side without any backend. In future I might try #Gdal #OGR #wasm to support more file formats and projections

@AtanasE is the 3rd a reference of the number of minimum files need to compose a #shapefile?
@stuartdunn I took a quick look. Easier said than done.
Here are all the churches in OSM: https://taginfo.openstreetmap.org/tags/amenity=place_of_worship#overview
Best I can find, the procedure is to use the "Overpass turbo" option (near the top right) to make a query and export the results (#shapefile not an option, but you might be able to convert kml or something else). In your case you probably just want nodes (points) and need to find a way to limit to England.
Query help is: https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_API_by_Example
@AtanasE any sight of that pesky #Shapefile fella?
Just in case I have your attention: what do the cool kids use these days for the #shapefile to #geojson conversion within a #nodejs script? #gis #programming
I thought I was late to the #zip #domain party, but there are still some things to break. #shapefile

A follow-up to the story about the GIS pro who loves shapefiles. This time, the protagonist meets Jill, a GIS developer who refuses to use anything other than Python 2. It's a reminder that sometimes, it pays to be a little bit stubborn and stick to our guns. #gis #shapefile #python #python2 #python3 #giscommunity #gispros #gischat #geospatial @atanas @RebelGeo @pokateo @sarae @anulahtinen @shapefile
Had ChatGPT write a heartwarming tale about a GIS pro who refuses to let go of his love for shapefiles. It's a reminder that sometimes, sticking to our roots and what we know can be more important than following the latest trends. #gis #shapefiles #geopackages #mapping #giscommunity #gispros #gischat #geospatial #shapefile @shapefile
Wow, we’re getting some big data sets. I’m 2023 let’s investigate alternatives to the #shapefile #mappymeme
