Running the QGIS OSM utilites to create a Spatialite db, I've noticed that during the last phase (converting nodes.ways to spatialite tables) a lot of data got lost.
I tested the Tuscany .osm file [1] and I extracted a portion of it with osmosis: toscana.osm.bz2 | ./osmosis --rx /dev/stdin --bounding-box top=43.7908 left=11.2153 bottom=43.7634 right=11.289 --wx "toscana_subset.xml" which appears to be complete when loaded in JOSM. Here are the counts on the tables generated by QGIS' OSM utilities: SELECT count(*) FROM ways union SELECT count(*) FROM toscana_osm_polylines count ---------- 221335 568129 More then a half ways are not translated. An example is: http://www.openstreetmap.org/way/16236141 Reading the OSM utils source code I thought an error would be raised in case of problems [2] but I didn't received any notice. giovanni [1] http://geodati.fmach.it/gfoss_geodata/osm/output_osm_regioni/toscana.osm.bz2 [2] https://github.com/qgis/QGIS/blob/master/src/analysis/openstreetmap/qgsosmdatabase.cpp#L500 -- Giovanni Allegri http://about.me/giovanniallegri Twitter: https://twitter.com/_giohappy_ blog: http://blog.spaziogis.it GEO+ geomatica in Italia http://bit.ly/GEOplus
