Issue with OSM tag #709

Open bramws opened 1 month ago

bramws commented 1 month ago

We use OSM tags for our app, since a few weeks we have an issue mostly with the historic tags. There a lot of castles who are tagged with historic=castle but the overpass turbo find only a few and we have the same issue with other historic tags.

I give an example around Brussels Belgium

https://overpass-turbo.eu/ node [historic=castle] ({{bbox}}); out;

He find only one castle but there are a lot more on the map and also tagged. We have the same issue with graphHopper so maybe the issue is not related to overpass turbo.

Thank you for your help.

You should use the wizard with the input "historic=castle". This would create a query including ways (and relations) which your current query misses.

Thank you, indeed with this query is works fine for the castle:

/ This has been generated by the overpass-turbo wizard. The original search was: “historic=castle” / [out:json][timeout:25]; // gather results nwr"historic"="castle"; // print results out geom;

The problem is our query is our native app with graphHopper. Was there a change in the last weeks?

graphHopper is a routing engine. I have no idea what your problem is with it. I do not know its api. Please try https://community.openstreetmap.org/

Thank you. For your information GraphHopper has also a Geocoding API https://docs.graphhopper.com/#tag/Geocoding-API

We receive help from OSM Belgium. The problem was we only search on Nodes and not on Way & Relation. The nwr["historic"="castle"] search on nodes, way & relation. Some of the historic data is changed from Nodes to Way or Relation.

Node: A single point with coordinates, used for simple points of interest (POIs) and as building blocks for more complex structures.

Way: A series of nodes that form a line or area, used for roads, boundaries, and regions.

Relation: A group of nodes, ways, and/or other relations, used to describe complex connections and structures.
