[OSM-dev] Osmium - "Corruption" when writing PBF

[Pris Matic]

Sorry!

I totally forgot I had already asked this :)

http://pastebin.com/GjtgqzkP  -  osmium handler header
http://pastebin.com/75JUT824  -  osmium handler source
http://pastebin.com/bSpGj0Ez  -  main.cpp

It should be possible to just run this on any map file as long as you set
the bounding box correctly in the handler source file. It takes a single
osm.pbf file, adds tag data, and outputs 4 quads from the original. It seems
to work find on some smaller data sets. On larger files, I get the corrupted
output I mentioned previously...

Regards,

Pris
