How to show 'arrowed lines' ON (NOT NEXT TO) one way roads and make them routable!

The following routine works on all devices and Basecamp/Mapsource. The principle is to add an invisible routing line to a one way highway.

Example for residential:

highway=residential & oneway!=* [0x06 road_class=0 road_speed=1 resolution 24]

highway=residential [0x12 road_class=0 road_speed=1 resolution 24 continue] # invisible routable line

highway=residential [0x10600 resolution 24] #extended line showing arrow

Adjust code to capture the useless 'oneway=no' , for example

oneway=no {delete oneway)

mkgmap automatically reverses nodes when oneway=-1 (minus one)

Ideally, use Garmin's 0x6 (and not 0x12) for residential routing purposes and make it transparent.
Then create two extended lines,one for 'not oneway' and another for 'oneway'

How to avoid routing along private highways

There are several ways depending on whether you want your map to route for all modes of transport , and legs as well

One of the safest - often used by Garmin - is to decide

1) on one mode of transport, ie pedestrian or bicycle

2) only use routable types (see below) for highways which allow bikes (pedestrians) - this cuts down on number of routable lines and thus speeds up the search for a route !

3) display any highway where bikes are not allowed as an extended type, ie using number 100+

4) In your typ file have copies of highways , as seen in Garmin typ files.

5) in you lines sheet filter out all access occasions where pedestrians (bikes) are NOT allowed -

highway=motorway|highway=motorway_link { add bicycle=no; add foot=no }

highway=residential & (access=private|access=no) & foot!=yes [0x11b00 resolution 24 ] # private housing estate

What are routable types?

0x1 - 0x13 , 0x16 , 0x1a , 0x1b

How to outline Woods & other Polygons

Polygons can have outlines of ANY thickness or ANY pattern , striped dotted etc, or ANY Color

Notice forest with exaggerated outline and woods/residential area with striped outline.

Lines are parsed before Polygons - see pdf for more details

How to show housenumbers/postcodes.

Recently,OSM address pois can be used for address searches although in a limited way - see mapuploader4 They can , however, always be plotted on your map.

Insert the following in your POINTS file

addr:housenumber=* { set name='${addr:housenumber}' } [0x1e04 resolution 24 continue ]

addr:postcode=* { set name='${addr:postcode}' } [0x1e04 resolution 24 continue ]

Add a new poi to your TYP file with number 1e04 ; this will centralise your poi on the coordinates supplied.

Make the poi transparent with width and height set to 1.

Note : If you don't add 'continue' , some POIs may not be rendered.

How to show steep hills using a symbol

In your points file add:

mkgmap:line2poi=true & mkgmap:line2poitype=mid & (incline=up |incline=down | incline=yes | incline=steep) [0xXXXX resolution 24]

use --add-pois-to-lines option and create a poi 0xXXXX in your typ file

How to show hiking or cycling routes using matching symbols

You can show symbols of a route by

1) creating a new poi in your typ file showing the symbol

2) Adding a condition in your Relations file This applies to a route with a reference=ABC -

check reference of route and substitute.

(route=foot | route=hiking) & ( ref ='ABC') { apply { set route_evw='$(route_abc):${ref}'|'${ref}' } }

For additional step by step help with clear illustrations see Creating OSM relations

3) Adding the following in your points file

mkgmap:line2poi=true & mkgmap:line2poitype=start & route_abc=* [0 x XXXX resolution 24] # ie XXXX = 3301

4) use --add-pois-to-lines option
