GRMN_TYPE

I was comparing a fairly new TYP file (r4905 mapnik.txt) with my own (grown from Openfietsmap quite a while ago) and noticed there was usually a line like this ;GRMN_TYPE: Roads/HIGH_SPEED_RAMP, RAMP/Highway ramp which is to be driven at high speeds/Non NT, NT or ;GRMN_TYPE: // What is the meaning of this? Thx Brad

Ranking of relations
by Bernard Mai 30 Jan '24

30 Jan '24

Dear all, I want to generate an overlay map to be used as additional layer on a Garmin watch. This layer can be turned on/off on the watch and should show only bicycle routes (route=bicycle and route=mtb). As most routes in openstreetmap are defined as relations I am using the following rules in my bike-routes style: *relations (file)* # Route relations as additional transparent layer for: # bicycle # mtb # bicycle routes type=route & route=bicycle { apply {set route='${route}';set route_name='$(route_name),${name}'|'${name}';set route_ref='$(route_ref),${ref}'|'${ref}';} } type=route & route=bicycle & network=icn {apply {set route_icn=yes;}} type=route & route=bicycle & network=ncn {apply {set route_ncn=yes;}} type=route & route=bicycle & network=rcn {apply {set route_rcn=yes;}} type=route & route=bicycle & network=lcn {apply {set route_lcn=yes;}} # mountainbike routes type=route & route=mtb { apply {set route='${route}'; set route_mtb_name='$(route_mtb_name),${name}'|'${name}'; set route_mtb_ref='$(route_mtb_ref),${ref}'|'${ref}';} } *lines (file)* # bicycle routes route=bicycle & route_icn=yes {name '${route_ref}'} [0x10f01 resolution 18-22 continue] route=bicycle & route_icn=yes {name '${route_name} (${route_ref})'|'${route_name}'|'${route_ref}'} [0x10f02 resolution 23-24] route=bicycle & route_ncn=yes [0x10f01 resolution 20-22 continue] route=bicycle & route_ncn=yes {name '${route_ref}'} [0x10f02 resolution 23 continue] route=bicycle & route_ncn=yes {name '${route_name} (${route_ref})'|'${route_name}'|'${route_ref}'} [0x10f02 resolution 24] route=bicycle & route_rcn=yes [0x10f03 resolution 20-22 continue] route=bicycle & route_rcn=yes {name '${route_ref}'} [0x10f04 resolution 23 continue] route=bicycle & route_rcn=yes {name '${route_name} (${route_ref})'|'${route_name}'|'${route_ref}'} [0x10f04 resolution 24] route=bicycle & route_lcn=yes {name '${route_name} (${route_ref})'|'${route_name}'|'${route_ref}'} [0x10f05 resolution 24] # mtb routes route=mtb {name '${route_mtb_ref}'} [0x10f06 resolution 23 continue] route=mtb {name '${route_mtb_name} (${route_mtb_ref})'|'${route_mtb_name}'|'${route_mtb_ref}'} [0x10f06 resolution 24] In general, these routes are drawn by mkgmap and I am able to generate an overlay map, but sometimes a route with "lower" priority (i. e. a route=mtb) hides a route with "higher" priority. In other words, I would like to show the routes in a ranking: The routes tagged with network=icn should be on top, followed by network=ncn and so on. The route=mtb should be only shown, if no other bicycle route is on the same way. Is this possible to achieve with mkgmap alone? Or do I need some sort of additional script to rank the relations before rendering them with mkgmap? I have read something, that the draw order depends on the ID of the relation and mkgmap renders the lower IDs first. But what about the higher relation IDs? It looks like ways tagged from the relation only get the tags from the relation with the lowest ID. Is this correct? Does anybody have an idea, how this could be overcome? Example: Way ID has 3 bicycle relevant relations: relation IDs 2119154, 9623717,2956920. With the style from above only the last one (relation ID 2956920, route=mtb) is shown although the second one (relation ID 9623717, network=icn) would be desired as it is an international bicycle route.

map types on different devices
by 7770 24 Jan '24

Hi. An observation, but maybe known to all mappers :-) I am using self defined TYP symbols for stay over huts or shelters along hiking trails or in the wilderness. It could be things like wildernes_hut lean_to shelter: https://wiki.openstreetmap.org/wiki/Tag%3Atourism%3Dwilderness_hut https://wiki.openstreetmap.org/wiki/Tag:shelter_type%3Dlean_to etc. For that i use the styles (points) to assign points in the group 0x2bnn (nn being a number). https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/ POI_Types#Type_0x2b_(Accommodation) According to the above page, eTrex devices may not show higher number than 0x2b07 in that group. What i notice is that GPSMAP 66s/st picks up higher values such as 0x2b11-0x2b18 and displays them, whereas eTrex 32x does not pick up those but i have to map the same symbols/icons to lower numbers (which not all are free). E.g., 0x2b07 works. I yet have to try exactly where the cut off is. Even if the eTrex 32x does not show the symbol on the map, at least some of the points can be searched for. If i have the map pointer close to the point and search for "all points" the points will show up in the list of close by points. But they do not show up under "lodging" category. Does anyone have additional details or guidance that i could read to see if i can find better numbers to assign so that the self made TYP definitions would show up on the etrex 32x device?

Border of polygon
by 7770 14 Jan '24

14 Jan '24

Hi. I read the TYP compiler manual but don't understand if it is possible to make a polygon to have: 1. transparent inner colour (this should be fine using "none" as colour i imagine). 2. adding a border with one or two colours, making the outline of the area/ polygon. If it is possible, can one set the border width as well? For example, i want to mark the boundary of a nature reserve, but not fill it. I attached a very small section of a larger polygon (from some other map), the outer colour is darker blue, the inner is lighter blue. Regards Karl
