Hello, I have an ubuntu server installed on a computer which have an i7 processor (4 physical CPU, 8 logical) with 8Gb of memory.
My objective is to extract a country data with completeWays & completeRelations = true, to have a better cutting than what we can have with the geofabrik cutting. For the moment, I can make it, but it's long, very very long (9/10 days of processing for the bounding-polygon operation). I'm sure I can improve this treatment by a better osmosis usage, but I don't understand stories about pipes, buffer etc. Here is how I actually process (for example, for the France country) : - Download european set (10.2 Go) - Apply a "bounding-bbox" of the country (2.7 Go) - Apply a "bounding-polygon" of the country (1.5 Go) The commands provides from a basic usage of osmosis : --read-pbf file=xxx.pbf --bounding + options --write-pbf yyy.pbf I first remark that with htop, I have 8 processors, but only one used. Maybe we can exploit the all computer performance by a "spacial command" ? Also, I don't need all osm data, and I know exactly which entity / tags I need, for example : Ways (tunnel, bridge, oneway, ref, z_order), Points (addr:housenumber, addr:housename, addr:street, addr:postcode, addr:city), Relations (admin_level), etc. Can you, please, help me to find the better steps / commands to make this job in the spirit of "what I need, how I need, where I need, when I need, not too much, not too less" ? Thank you for your help, very much, and sorry for my bad english (I will improve it ;) See you later, Kin
