[mkgmap-dev] default style improvements / upated typ-file

From Joris Bo jorisbo at hotmail.com on Sun Jan 13 11:11:13 GMT 2019


I modified the type-file up to Ticker's changes in build  r4262.
Latest changes can also be found on https://github.com/Jorisbo/Mkgmap-Mapnik-Style-Garmin
It already reflects some new mapnik colors which will be first visible on www.openstreetmap.org in a couple of days

The deltas I found after comparing Tickers changes are
Added rendering for polygons
	place=suburb [0x02 resolution 19]
	# mop up any remaining water areas
	waterway=* & waterway!=no & area!=no {add name='${waterway|subst:"_=> "}'} [0x3b resolution 22]
	natural=water & area_size() < 100000 [0x41 resolution 22]  # Small Lake
	dock=drydock [0x4c resolution 22]  # might also have natural=water
	natural=water & water=lock [0x4c resolution 22 default_name 'Lock']

Added rendering for lines
	highway=raceway | highway=gallop {add name='${highway}'} [0x30 resolution 23]

Some changes to be considered?
Different kinds of public transport are mapped to the same symbol. For now I choose the arbritary bus_station as the most common
	Line 106: amenity=bus_station [0x2f08 resolution 23]
	Line 126: amenity=ferry_terminal [0x2f08 resolution 22]
	Line 206: railway=station [0x2f08 resolution 22]
	Line 207: (public_transport=platform & rail=yes) | railway=halt [0x2f08 resolution 23]
Different kinds of roads mapped to the same linetype, especially cycleways deserve there on linetype I think
	Line 190: highway=bridleway [0x07 road_class=0 road_speed=0 resolution 23]
	Line 197: highway=service & service=parking_aisle [0x07 road_class=0 road_speed=1 resolution 24]
	Line 198: highway=service & (service=alley | service=driveway) [0x07 road_class=0 road_speed=0 resolution 23]
	Line 199: highway=service [0x07 road_class=0 road_speed=2 resolution 22]
	Line 201: highway=cycleway [0x07 road_class=0 road_speed=1 resolution 23]
	Line 214: highway=turning_loop | highway=turning_circle | highway=layby | highway=escape | highway=emergency_bay [0x07 road_class=0 road_speed=0 resolution 24]

Add different (non-routable) linetype for highway = construction instead of converting them to a routable footway (0x16)

Any comments, please let me know,
Kind regards Joris

Hi Gerd

Here is summary of the changes:

A few minor layout tidy-ups

Add GBR section to inc/access_country

Do aeroway=runway/taxiway/taxilane as lines unless marked as area=yes and show these lines even when also a highway

Ignore more highways when abandoned/disused/demolished

Ignore more highway tags that are not suitable for routing

highway=steps/corridor/stepping_stones/elevator/escalator/platform to footway with bicycle=no and remove later test for steps

Convert highway=crossing/virtual to path

Don't convert footway to cycleway, but more rules to convert path to footway/cycleway/bridleway

Add footway around man_made=pier even if area=yes

Fix common bad tagging for highway= by converting to the presumed values

Put routable path around highway=pedestrian closed areas; squares/plazas often don't have other routing joining all entry/exit ways. Similarly for footway. Then continue to allow any polygon processing

Handle some rarer highway types by converting to more generic type

Show any other water lines

Removed all the {set cityxx/tmp:city}, & cityxx/tmp:city!=yes, continue with_actions bits from place=city/town...

Group the rules amenity=restaurant/fast_food, cuisine= to clarify, simplify and show better how it relates Garmin "Food & Drink" search and add some more cuisines. One effect of this is that amenity=fast_food,cuisine=pizza/grill moves to the "Fast Food"
category. The other effect is that an element that is both a Restaurant and a Lodging now shows as Lodging rather than Restaurant

For leisure=* where sport might be involved, show the sport if no name available

Show canal/lock as 0x6505 (Water Features>Canal)

Show aeroway=runway/taxiway/taxilane as polygon only if marked as area=yes

Increase resolution that amenity=cafe/fast_food/restaurant polygons show at

Show place=suburb

Alternative rule to show highway=pedestrian as square/plaza unless explicit area=no. highway=footway show as square/plaza if explicit area=yes

Don't assume any other closed highway is parking area, just services/rest_area

Show more historic=*

Show drydock, canal & lock differently from standard natural=water, and use a different code for small lakes

Show any other water area

Show all man_made=* unless explicit area=no
