Hi all, I need help for a slightly offtopic problem. I've got a (huge) list of addresses in CSV format. I want to add them to the pbf file from geofabrik before running splitter/mkgmap. Those addresses aren't in OSM. I converted the CSV file to an .osm file. The script produces the addresses with a negative osm id. I then use osmconvert : ./osmconvert geofabrik.osm.pbf addresses.osm --out-pbf -o=complete.pbf No error returned. The complete.pbf file is correctly processed by the splitter/mkgmap toolchain. But the map doesn't show the addresses. I tried to look for the problem : - The .osm file seems correct, it opens correctly in JOSM. - Converting the .osm file to .pbf format before merging doesn't help - Something funny : after merging, the .pbf file is slightly smaller than the geofabrik one. osmconvert does a more efficient job at creating pbf files ? I guess that the problem lies in the merging part but I didn't find any inspection tool for the pbf format. Can anybody help ? Paco.
