Why not ask your question on the new OpenStreetMap Community Forum?

Hi there,

I have a problem to understand how the API works.

These two lines work well:

wget -c http://api.openstreetmap.fr/xapi?"node[waterway=wreck][bbox=-27,29,44,72]" -O EU_Wrecks-1.osm
wget -c http://api.openstreetmap.fr/xapi?"node[historic=wreck][bbox=-27,29,44,72]" -O EU_Wrecks-2.osm

But when I try to combine them it doesn't:

wget -c http://api.openstreetmap.fr/xapi?"node[waterway|historic=wreck][bbox=-27,29,44,72]" -O EU_Wrecks.osm

Any hints for me? Tnx...

PS: Seems it worked once: https://wiki.openstreetmap.org/wiki/User:Sparcuser

Rather than "node[waterway|historic=wreck]" you need to do something like "(node["waterway"="wreck"];node["historic"="wreck"];);"

Also note that the wizard of https://overpass-turbo.eu/ can be very helpful for figuring out what works

Thanks for your answer!

I tried wget -c http://api.openstreetmap.fr/xapi?"(node["waterway"="wreck"];node["historic"="wreck"];);[bbox=-27,29,44,72]" -O EU_Wrecks.osm and got ERROR 400: Bad Request.

When I send only the http part in my broser I get:

Error in ["(node["waterway"="wreck"];node["historic"="wreck"];)]: Error: Query must start with 'node', 'way', 'relation', or '*'

Tested with dozends of variants with or without brackets, quotes, ... :-P

In the Overpass Turbo wizard mentioned above I wrote "type:node & (waterway=wreck | historic=wreck)", which it then translates to QL code.

(when tested from inside JOSM the result is a bit different)

What I'm not at all sure about here is how to transform the result into something that will fit into a commandline string like yours

The Overpass server implements an XAPI compatibility layer. I don't know it well, it may not support the combined query.

You can use the Overpass QL to do the query though, I think Hjart has written their answer in the QL. Here's the query in Overpass Turbo:


(Click "Run" to see the output)

Under "Export" there is a link "raw data directly from Overpass API" that is suitable for use with wget.

The query language is documented here: http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL
