Release of a world map

[bchapuis]

I recently got a dedicated server aimed at producing a world map. I still encounter some issues with the geometries of some relations in planet.osm.pbf, hence the small fixes here and there and the increase in the number of releases.

The preliminary results are very encouraging. A planet database import take about 24hours and the time taken to index the data is about the same. More details will be posted here soon.
