- This layer will automatically load  [osm-buildings](./osm-buildings.md)  into the layout as it depends on it:  A
  calculated tag loads features from this layer (calculatedTag[0] which calculates the value for _
  overlaps_with_buildings)
- This layer will automatically load  [generic_osm_object](./generic_osm_object.md)  into the layout as it depends on
  it:  A calculated tag loads features from this layer (calculatedTag[18] which calculates the value for _
  intersects_with_other_features)

Basic tags for this layer
---------------------------



Elements must have the all of following tags to be shown on this layer:

- HUISNR~^..*$
- man_made!~^mast$

Supported attributes
----------------------

### Import-button

_This tagrendering has no question and is thus read-only_

- **{conflate_button(osm-buildings,building=$_target_building_type; source:geometry:date=$_grb_date; source:geometry:
  ref=$_grb_ref; addr:street=$addr:street; addr:housenumber=$addr:housenumber, Replace the geometry in OpenStreetMap and
  add the address,,_osm_obj:id)}** corresponds with _overlap_percentage>50&_reverse_overlap_percentage>50&_
  overlaps_with!~^$&addr:street~^..*$&addr:housenumber~^..*$&addr:street!=&addr:housenumber!=
- **{conflate_button(osm-buildings,building=$_target_building_type; source:geometry:date=$_grb_date; source:geometry:
  ref=$_grb_ref, Replace the geometry in OpenStreetMap,,_osm_obj:id)}** corresponds with _overlap_percentage>50&_
  reverse_overlap_percentage>50&_overlaps_with!~^$

### Building info

_This tagrendering has no question and is thus read-only_

### overlapping building address

_This tagrendering has no question and is thus read-only_

- **The overlapping openstreetmap-building has address {_osm_obj:addr:street} {_osm_obj:addr:housenumber}** corresponds
  with _osm_obj:addr:street~^..*$&_osm_obj:addr:housenumber~^..*$
- **The overlapping building only has a street known: {_osm_obj:addr:street}** corresponds with _osm_obj:addr:street~
  ^..*$
- **The overlapping building only has a housenumber known: {_osm_obj:addr:housenumber}** corresponds with _osm_obj:addr:
  housenumber~^..*$
- **No overlapping OpenStreetMap-building found** corresponds with

### grb_address_diff

_This tagrendering has no question and is thus read-only_

### overlapping building type

_This tagrendering has no question and is thus read-only_

### apply-id

_This tagrendering has no question and is thus read-only_

### apply-building-type

_This tagrendering has no question and is thus read-only_
