Hello! Currently I am getting a little bit confused with all of the development being done on mkgmap. I have read about making streets searchable and that it does decrease performance and that there is a parameter to suppress sorting of streets. But when are features like this executed? Do they need a parameter to activate them? Or do they need a parameter to suppress them? I have read about a patch do create a certain type of shields on the highways. But what if I don't need them or want them to look differently? So I wanted to ask what does mkgmap do by default? What can be activated, what needs to be deactivated? Or more specifically: I just want to build a huge topological map and need good performance for that. I do not need routing and no searchable streets. So how do I need to call mkgmap? confused Nop

Take a look at the output that --help=options produces. That will tell you quite a lot about the behaviour of mkgmap.
Unfortunately, this output tells me nothing about the dependencies. E.g. --ignore-turn-restrictions Do I need this? Sounds like it was relevant only for routable maps. But where do I switch routable maps on or off? Or are they always on? --no-sorted-roads Do I need this? Or do I only need it if I use --road-name-pois[=GarminCode] (which I am currently not doing)? I don't find any reference to the highway shields so I guess it isn't in r1001. Or would something like that be added without a switch? bye Nop

You need it if you want to ignore turn restrictions in routable maps. Routing is not enabled by default - you need to specify the --route option for that (yes, I know, that isn't mentioned in the help).
--no-sorted-roads
Do I need this? Or do I only need it if I use --road-name-pois[=GarminCode] (which I am currently not doing)?
It is independent of the road name pois feature.

That feature is not yet in the trunk. Cheers, Mark

It is independent of the road name pois feature.
So is it dependent on another switch? Or do I always have to give this parameter or suffer a performance penalty? bye Nop
Nop,

Well, most people will want to have the address find feature so generating the sorted road data is enabled by default. If you can't live with the performance hit, specify the parameter. Cheers, Mark
