Settlement area from buildings layer

Question

I'm using QGIS 3.22.0 Bialowieza. I have an osm-building-Layer. I would like to transform the single buildings into a settlement area as you can see in the image.

In the image you can see the buildungs (yellow as a layer), in the background you can see a basemap. In the basemap the settlement area as a whole is shown (in grey). I thought by merging the building-layer I could get a settlement area, but obviously this didnt work. Is there a way to solve this?

Answer 1

In QGIS [3.26 used]

Zoom to Area of Interest Load the Quick OSM tool

go to Query in the tool

use the code

/*
This has been generated by the overpass-turbo wizard.
The original search was:
“landuse=residential ”
*/
[out:json][timeout:25];
// gather results
(
  // query part for: “landuse=residential”
  node["landuse"="residential"]({{bbox}});
  way["landuse"="residential"]({{bbox}});
  relation["landuse"="residential"]({{bbox}});
);
// print results
out body;
>;
out skel qt;

The query will create a temporary virtual layer OSMQuery
