Querying OSM to find forests+woods?

General talk
1

Hello,

I’d like to find all the woods and forests in a given region. The following times out even at 60s, so I suspect it’s not the right way to query OSM.

Any idea?

Thank you.

[out:json][timeout:60];

//Region
rel(8649);
map_to_area -> .searchArea;

(
//BAD: Returns bunch of dots
//relation[landuse=forest](area.searchArea);

//BAD: Times out
way[landuse=forest](area.searchArea);
);

out body;
>;
out skel qt;

For any sizeable area, e.g. a country, state or province, I really recommend you to download a geographic extract in PBF format from the Geofabrik website:

https://www.geofabrik.de/

And then use e.g. Jochen Topf’s “Osmium Tool” (in the “Synaptic Package Manager” of Ubuntu listed as “osmium-tool”) to extract all the woods and forests. Jochen gave an example query for that on this webpage under the heading “10. Filtering by tags”:

https://osmcode.org/osmium-tool/manual.html

I have used this workflow with success for extracting all woods and forests of a 50GB planet download.
