Hi Greg,
I think we should remove (ignore) the --route option, as it is mandantory. If possible, we should allow to create maps that don't contain a NOD section, I think this is wanted by some users.
I'm not sure what you mean. It sounds like having basic/advanced/routing is desireable from the list consensus. But I would suggest that routable maps be the default, when mkgmap is invoked without special arguments. Perhaps keep --net and --route, but allow --no-net and --no-route and make --net and --route default (and of course make route imply net)
What I meant is this: The current implementation of mkgmap does more or less assume that --route is used. Many functions are not executed without that option, although they are not needed for routing, only for the creation of the NET data. For example, --housenumber has no effect without --route, but if I got that right you may want to be able to search for housenumbers without being able to route to them. NET data is not written without --route. In the current implementation it is not simple to write NET data without also writing NOD data. I agree that we should support NET without NOD. Gerd
