[mkgmap-dev] Binary OSM file support?

From Chris Miller chris_overseas at hotmail.com on Wed Sep 8 20:27:20 BST 2010

Hi Jeff,

Scott Crosby posted a message to this list back in June asking for comment 
on his binary format. My thoughts at the time were that it looked rather 
promising and adding support for it to the splitter would be a good idea, 
though I was reluctant to use it other than internally if the file format 
wasn't relatively stable because of the maintenance problems that it might 

I haven't been following the discussions on the Osmosis side (and indeed, 
have had hardly any time to dedicate to the splitter lately either), but 
it sounds like this file format is now at release candidate status in Osmosis? 
If so I think that's great news! I can't speak for the other developers on 
splitter or mkgmap, but personally at least I'd really like to see a revamped 
splitter and mkgmap that can work with the format directly - there are clearly 
some huge benefits to be had from going that route. Perhaps Scott, Steve 
and co can chime in with their thoughts on the topic and where they see things 
heading from here?
