Dear mobile developers,
We all have the same problem: the XML OSM format is not efficient for mobile
devices.
For the time being, we all develop our own solution to transform the XML in
whatever binary format suitable for a mobile application, often forcing the
user to use a specific desktop
Hello Chris,
not only for mobile devices but for Laptops too
I'd really apreciate a binary-format.
Do you intend to save all the data OSM has
or only support a subset required for routing
and map-rendering?
Do you think about floating-point or fixed-point
coordinates?
We could start by
indeed, every application has other requirements
- editors, wants all data, read/write
- rendering, wants (very) limited datasets, readonly
- routing, remote or local ?
i like the discussion

The idea is to have a binary format specification.
The actual organization of the files will be up to the application.

This is one of the things to discuss. For mobile applications, fixed-point
is the most efficient but we have to balance this with the loss of
precision.

I currently use my own implementation for my java mobile routing and navigation
implementation (see we-travel.co.cc), though I would be very happy to switch to
a common implementation or help develop such an implementation if this fits my
needs.

Thank you Pol.
It sounds great,
can someone start organizing what we have on a wiki-page?
I guess we should get a concensus on the purpose of the applications
what are to be offered usage of this file-format first.

I propose it to be ment for routing and navigation.

Hi All,
I'd like to disable the daily bz2 changeset files once and for all. I
intend to do this over the next day or two. Yell if you want me to keep
them going for a bit longer.

There's a reason people use XML, it's an interchange format but binary

I built a fast tile browser that, because of all the flash and
javascript is faster than the normal map browser at openstreetmap.org.
It simply shows 4 tiles, zooms to that tile if you click on it, goes

Hi Marcus,
normaly the company as Teleatlas or Navtech sell their data in some
public format as shape or GDF , then the data is organized in different
way , but is not binary data. Is not possible to share this kind of
technical information because We sign a NDA. But if you have some
question

Good idea :)
I am always tempted to do my own binary vector map format after suffering the
madness by Garmin. However the wonderfull world of raster maps keeps me from
doing it.
Anyway, I would suggest you have a deep look into the Garmin binary
sepcification. Some things are good, some are
