[OSM-talk] Map and Programm for Offline

[john whelan]

There is a Google mailing list for support maperitive at googlegroups.com

http://maperitive.net/

Recently there has been some discussion there on how to reduce the size of
off line maps.  Whichever software you use it is likely that it will want
to hold the data file in memory so I suspect you'll need to split up the
file.  .pbf format can help substantially over .osm format, removing tags
that won't be displayed such as source and author details can help as well.

What you need on the display at one time is a fairly small amount of data
so sp

Try it with a smaller data file.  Be aware that not all software that
manipulates the data files leaves it in a state that everything can use
it.  You need to be aware of XML and how it works sometimes to make sure
the headers are correct.

It should be simpler but it isn't and Maperitive is one of the better off
line solutions.

Sorry
