How to create offline map

[Sjors Provoost]

Hi there,

The new location application looks very promising. I'm glad to see it
is using OpenStreetMap.

I would like to create some offline maps the place that I live
(Melbourne) and some places that I will be traveling to next week
(Adelaide, Alice Springs, Katherine, Darwin).

I've read http://wiki.openmoko.org/wiki/Om2008.8_Locations but I do
not understand the instructions at the end:

>  om-locations-map-pack /tmp/diversity-maps my_map.eet

>From the help:

> om-locations-map-pack [-b base] [-d version,source,min_level,max_level,lon,lat,width,height] <cache-dir> <output>

I assume lon and lat refer to the center of the map? Width and height
refer to the size of the map? In meters, in degrees?

What is meant by version, source, min_level and max_level?

One example would probably help me a lot.

Kind regards,

Sjors
