How to create line draworders in Basecamp
|
Forget about line draworders on your gps as there is no logic to the algorithm - ie bridges over dual carriageways or motorways often only overlap one of the highways . However, it is possible to force line draworders in Basecamp.
One way to get 'overlapping' bridges is by placing them all in one img and make the priority of this map higher than the rst of the maps - in my experience, this is not guaranteed to work.
The following applies to Basecamp and more than likely will not apply to your gps device.
Bridges

- Routable types have a higher draworder then non routable ones
- Changing a non routable line from a bitmap to a non bitmap gives it a higher draworder
- Change rivers, streams etc to bitmap lines - In TYPWiz.click 'Convert to Bitmap' .
- Some extended type numbers also have a default higher draworder , ie 108
The following procedure is just one way of creating bridges Problem: You can't use 0x1 for a Motorway as nothing crosses 0x1 ! Solution 1 Bridge No Outline: | |
| Use 0x1 - 0x7 as bridges | highway=motorway & bridge=* [0x1 road_class=4 road_speed=7 resolution 24 continue] |
use 0x12 for mways and make this line TRANSPARENT | highway=motorway [ 0x12 road_class=4 road_speed=7 resolution 16 continue] |
| use an extended line number to show the motorway AS A BITMAP | highway=motorway [ 0x10108 resolution 16 ] |
Solution 2 Bridge With Outline: | |
| Use 0x108 as a a transparent bridge outline | bridge=* [0x1 resolution 24 continue] |
| Use 0x1 - 0x7 as bridges | highway=motorway & bridge=* [0x2 road_class=4 road_speed=7 resolution 24 continue] |
use 0x12 for mways and make this line TRANSPARENT | highway=motorway [ 0x12 road_class=4 road_speed=7 resolution 16 continue] |
| use an extended line to show the motorway AS A BITMAP | highway=motorway [ 0x10108 resolution 16 ] |
Using this method you can have railway lines / even canals ALWAYS crossing motorways and other highways.For railway lines perhaps use type 0x0 (no bitmap)
The draw back is :
- you will need to reorganise you highway numbers
- You are having to create extra lines
