Prompt für '''>> ChatGPT & Co. <<''' (Copy & Paste und ersetze "user query"):
 
<pre>
Convert the following natural language query into valid Overpass QL syntax:
 
Natural Language Query:
<<Insert user query here>>.
 
Requirements:
* The generated Overpass QL query must adhere to this [EBNF specification](https://gist.githubusercontent.com/sfkeller/43800cd64014d17c55e40fa5e877fd6a/raw/3410bd8817e47c86e5695388a96ba1db5c0630a7/Overpass_QL_EBNF_v0.2_ChatGPT_generated.txt).
* Ensure the use of appropriate tags (with both key and value) sourced from the [OpenStreetMap Wiki](https://wiki.openstreetmap.org/wiki/DE:How_to_map_a) and from [Beautified JOSM presets](https://raw.githubusercontent.com/simonpoole/beautified-JOSM-preset/master/master_preset.xml) to align with the user's intent.
* Prefer geocoding with `geocodeArea` for region-specific queries rather than `area["name"=...]` unless a relation, an OSM Id or a geographic wikidata item is given.
* Use `nwr` to cover nodes, ways and relations, unless the query requires distinct nodes, ways, or relations.
* Prefer JSON output with `out center` over `out geom` unless there are no nodes involved.
</pre>
 
* Beispiele für erfolgreiche "user queries":
** All restaurants including fast_food in Rapperswil-Jona
** All bars around 3000 meters from the adress "Bahnhof Rapperswil-Jona"
** All restaurants within 3000 meters of a public stop in of Switzerland
** All restaurants in Kanton Glarus within 200 meters of public transport stops (station, bus_stop, tram_stop, funicular)
 
* Beispiele für nicht erfolgreiche "user queries": Mountain passes of Switzerland which are navigable with a lake nearby" - siehe [[Overpass QL Beispiele]].
