天桥Turbo中的位置查询

Question

I have just learned about the overpass turbo service and its ability for querying data. I have tried the following query and it works fine:

[out:json][timeout:25];
(
node["highway"]({{bbox}});
);
out body;

But when I replace the bbox with a name of city which according to the wiki page of overpass it should be like below, the code gives an error. Would be glad to know what is the problem with the second code?

[out:json][timeout:25];
(
node["highway"]({{geocodeId: Vienna}});
);
out body;

error message:

An error occured during the execution of the overpass query! This is what overpass API returned: Error: line 3: parse error: Unknown query clause Error: line 3: parse error: ')' expected - 'node' found. Error: line 4: parse error: Unknown type ")" Error: line 4: parse error: An empty query is not allowed Error: line 4: parse error: Unknown type ";" Error: line 5: parse error: An empty query is not allowed

Answer 1

As you want to query nodes in a certain area, you need to use the following syntax for overpass turbo:

[out:json][timeout:25];

{{geocodeArea:Vienna}}->.searchArea;
node["highway"](area.searchArea);
out body;
