Using overpass-turbo.eu I want to query different types of elements near a certain point. Here's an example which returns all trees 150 meters around Big Ben in London.
[out:json][timeout:25];
(
node[name="Big Ben"]["addr:street"="Bridge Street"];
node(around:150)[natural=tree];
);
out body;
>;
out skel qt;
It works for all trees. But what if I for example also want to find all shops 150 meters from Big Ben? Due to overpass' flow concept, I can use the Big Ben node only for the query next to the line where I've queried for Big Ben.
What I may need to do is to store Big Ben's node in a variable to access it for all queries following. How does this work?
Simply use the following Overpass syntax:
(around:radius,latitude,longitude)
In this case:
node(around:150, 51.50069, -0.12458)[natural=tree];
