How to get started with the overpass API?
Simply click on the Icon next to each query to try it in overpass turbo! The simplest way to get started with Overpass API is to use Taginfo and to navigate to the tag you are interested in. Take post boxes as an example. Push the Overpass Turbo button there in the upper right.
Which is more concise overpass or Overpass Turbo?
Overpass Turbo nowadays can directly process the results of out geom and out center and the delivered raw data is more concise. As a last step, we make the query more concise:
How does Overpass Turbo work on OpenStreetMap?
The Overpass Turbo user interface has a lot of capabilities. For the moment it should suffice that you have in the upper left corner of the map view a textfield. Type in your favorite location. It will then, with the use of Nominatim move the map view to that location.
Why do we have a bounding box at the beginning of a query?
But we have brought the bounding box to a single place in the beginning of the query. An important reason to do so is that you should develop the habit of having always a bounding box unless you really want results from all over the planet.
How to find intersection by searching name of 2 streets?
I need to find intersection by searching name of 2 streets; I found overpass API to query on osm data; the way I found was to find a node near a way; but the problem is all nodes don’t have name and in most cases the answer isn’t accurate, is there a better way? You could use the following approach:
How to search for an intersection in Java?
It keeps crossing, if you don’t need it, just substract the set of crossing to the intersection node (node.n3.n2). Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
How to calculate the intersection of input set?
Edit: node.n1.n2; calculates the intersection of input set .n1 and .n2. Please check the documentation for details. Works fine for me. Could be enhance. It keeps crossing, if you don’t need it, just substract the set of crossing to the intersection node (node.n3.n2).
How to load data from overpass API in LibreOffice?
/* CSV-Format: To load the query results in LibreOffice, click on “Export” -> “Open Raw Data directly from Overpass API” in overpass turbo. Fields are tab-separated.
Why do we have parentheses in the query statement?
An important reason to do so is that you should develop the habit of having always a bounding box unless you really want results from all over the planet. We also have grouped the query statements by an union statement – these are the parentheses. This allows to have only a single output statement.
How do you move a map in OpenStreetMap?
For the moment it should suffice that you have in the upper left corner of the map view a textfield. Type in your favorite location. It will then, with the use of Nominatim move the map view to that location. Type in e.g. Manhattan and choose the first hit. The map then jumps to the upper end of the Central Park in Manhattan.

Why is geometry missing in OpenStreetMap data model?
Running this query will result in a message that geometry is missing. This is because the OpenStreetMap data model does not directly associate coordinates to ways and relations. Ways and relations instead get their geometry by resolving their node references.
