Create pbf files for areas covering multiple geofabrik regions #16

Closed Hagellach37 closed 6 years ago

Hagellach37 commented 6 years ago

Currently the input area for realtimeosm tasks can't intersect with multiple major geofabrik regions.

Let's see how we can fix this:

Idea 1: We need to know whether overpass API can handle the load. The Wiki[https://wiki.openstreetmap.org/wiki/Overpass_API#Limitations] specifically states that downloading large regions is advised against. I just ran a query on our local overpass API:

(
   node(29.48,-51.52,52.09,14.45);
   way(29.48,-51.52,52.09,14.45);
   relation(29.48,-51.52,52.09,14.45);
);
out count;

The bounding box (format: South, West, North, East) mostly covers the atlantic. It fails saying that it needs at least 513MB RAM. So I guess overpass cannot handle our loads. But feel free to experiment with your own bounding boxes!
