[OSM-dev] Directly reprojecting OSM/PBF files?

[Jukka Rahkonen]

Hi,

I suppose you want the output to be in some OSM format but GDAL OSM driver
is read only so I fear it is not your tool. You may want to compare the
speed of what ever solution you will finally use with GDAL. It reprojected
yesterdays great_britain.osm.pbf (464 MB) into EPSG:27700 and saved the
result into Spatialite database in 6 minutes and 3 seconds. I fooled a bit
and saved several minutes by turning off the spatial index creation.

C:\GDAL_dev>time
Nykyinen aika: 11:28:16,44
Anna uusi aika:

C:\GDAL_dev>ogr2ogr -f SQLite -t_srs epsg:27700 -dsco spatialite=yes
great_britain.sqlite great_britain.osm.pbf -gt 20000 -progress
--config OGR_SQLITE_SYNCHRONOUS OFF
--config OSM_COMPRESS_NODES YES -lco SPATIAL_INDEX=NO
0...10...20...30...40...50...60...70...80...90...100 - done.

C:\GDAL_dev>time
Nykyinen aika: 11:34:19,50
