Preventing Routing Node Creation
Please excuse me coming to this mailing list with a 'beginners' question but, believe me, I have searched widely without a solution. I would like to know if is possible in a 'routing generation' compile to have a command in the style 'lines' file which will prevent creation of routing nodes completely for a specific code for which such nodes would normally be created. For example can something like this be used: highway=* {add mkgmap:abxdef-ghj=false} [0xXX] Where 0xXX is the routable Garmin code. Thanks for any guidance. Bill.
two solutions come to mind: 1. use a non-routable code 2. highway=* {set access=no} [0xXX] Am 19.07.2011 11:45, schrieb Bill Lancashire:

Many thanks for your suggestions. !. I want to use the code because of it's desirable rendering features compared to an extended type of code. 2. I've thought about this one, but does it prevent routing by any means?. I guess the routing nodes will still be formed. Bill. michael lohr wrote:

1. what do you mean by desirable rendering features? 2. to be honest, i never tried it extensivley. it works if there's only a couple of roads like this around, but i don't know if the device forces routing if say 80% of the roads have access=no. i always use a non-routable code to prevent routing (ie. highways and bicycle routing) Am 19.07.2011 13:39, schrieb Bill Lancashire:

1. what do you mean by desirable rendering features? Certainly on my devise (GPSMAP 62s), where a road having one of the standard default Garm,n routable codes makes a junction with a road having a custom 'extended' type code then the former 'pushes into the latter making the result rather unsightly.
I am wanting to use one of the 'routable' standard codes to draw the roundabouts with an 'overlay'. However, as I already have the roundabout code (0x0c) in invisible form on the same region of road I want the overlay to be non-routable otherwise there will be two routable lines in the same place in the same layer.

Hi
I would like to know if is possible in a 'routing generation' compile to have a command in the style 'lines' file which will prevent creation of routing nodes completely for a specific code for which such nodes would normally be created.
There are no routing nodes by default in the style language. If you want them you have to add road_class and speed: eg: highway=secondary [0xXX road_class=2 road_speed=3] This will cause mkgmap to add the routing nodes to the map. It may not completely stop mapsource or a device using it particularly if there is no other way, although on a quick test it did and only straight line routes were drawn to the road. ..Steve
