get surrounding buildings to a set of nodes with specific tags

Question

Dear all,

I want to query overpass-turbo.eu for all buildings that contain at least one node with the tag "country=EU" and "office=government".

I tried so far:

node({{bbox}})[country=EU][office=government];
is_in;
(way[building](pivot);>;);out;

Test on overpass: http://overpass-turbo.eu/s/MaJ (courtesy of mmd)

However, this does not work as areas are not always updated (see discussion with mmd and on github). The results are not complete and not reliable.

Then, I tested to achieve this with the around operator.

[out:json][timeout:25];
// fetch area “Brussels” to search in
{{geocodeArea:Brussels}}->.searchArea;
// gather results
node[office=government][country=EU](area.searchArea)->.offices;
( 
  way[building=yes](around.offices:8);
);
// print results
out body;
(._;>;);
out skel qt;

Test on overpass: http://overpass-turbo.eu/s/Mbp

However, here I do not know how to choose the distance of the around operator. The results are either incomplete or I get false positives, i.e. also neighbouring buildings.

Is there a solution to get the surrounding building of a set of nodes with specific tags?

Answer 1

This is my best take so far:

[out:json][timeout:25];
{{geocodeArea:Brussels}}->.searchArea;
// get EU governmental offices nodes
node[office=government][country=EU](area.searchArea)->.offices;
(
        // get all enclosures from EU governmental offices
        .offices is_in->.enclosing;
        // limit result to buildings
        way(pivot.enclosing)[building=yes]->.officebuildings;
);

.officebuildings out geom;
.offices out meta;

Run in overpass turbo: http://overpass-turbo.eu/s/NID

The problem is yet that some buildings are not marked (most of them?).
