Completeness?

Posted by AlexSpritze on 27 January 2026 in German (Deutsch).

For the German regions of Sachsen-Anhalt and Niedersachen, I thought there are probably all buildings mapped. At least those called Einfamilienhaus or Reihenhaus.

But I found that with the following overPass query, many potential spots for missing buildings data can be found:

way["landuse"="construction"]({{bbox}});

And because of that my change set statistics of today is as follows:

Edited on 2026-01-27:

  • 2281 nodes
  • 404 ways
  • 1 relation

Most used tags for nodes:

  1. natural (371)
  2. addr:housenumber (48)
  3. addr:street (48)
  4. addr:postcode (46)
  5. addr:city (46)
  6. entrance (36)
  7. addr:country (26)

Most used tags for ways:

  1. building (319)
  2. landuse (22)
  3. highway (16)
  4. amenity (9)
  5. addr:postcode (9)
  6. addr:city (9)

Conclusion

Many buildings have been added (and some trees 🌳👼) in Niedersachsen and Sachsen-Anhalt.

But as the query suggests, there are still some construction sites which can be investigated. Probably this “trick” is already known to hardcore-mapper ;)

Okay, warum nicht mal filmen, was man so bei OpenStreetMap für Änderungen vornimmt?

Geht zum Glück schneller als gedacht, auch wenn das erste Video nur ein One-Shot ist, ohne weitere Bearbeitungen und ohne Ton. Naja, die bewegten Bilder sprechen für sich.

Stolpersteine

Einige Stolpersteine haben keinen Commons-Bilder, weil sie eigentlich Sammel-Stolpersteine sind

area["de:amtlicher_gemeindeschluessel"="15002000"]->.municipality;
(
nw[!"wikimedia_commons"]["memorial"="stolperstein"]
  (area.municipality);
);

Noch mehr Commons-Bilder für diverse Nodes

area["de:amtlicher_gemeindeschluessel"="15002000"]->.municipality;
