Re: [mkgmap-dev] route recalculation senstivity bug found

Nuvi 255 here. Route recalculation works very well now (25/30m). I remember a month ago (+/-) it was much worse (say > 100m). Mark, do you have some advice about OSM tagging for address search? Ciao. --- Sab 13/6/09, Mark Burton <markb@ordern.com> ha scritto:

Hi Felix,
I found out the problem associated to route recalculation not working (well working but only far too late). We currently set the TRE header at 1,3,17 IF we change this over to 1,4,23 route recalculation kicks in at around 25-30m instead of 300-400 (as it happens with 1,3,17 we currently use) on my Vista HCx.
I don't know how this is set because the value introduced with the patch about this seems to be organized differently. I changed this with gmaptool and now it works very well. Would be great if these values could be set directly by mkgmap.
With my vista hcx and using the current value of 0x110301, the route recalculates if I go off course by no more than about 25m. I believe other people are also getting similar results. Perhaps people could confirm that?
Cheers,

Hi Marco,
Mark, do you have some advice about OSM tagging for address search?
If a road has a name or reference it will have an entry in the address search data structure. It needs also to have a city associated with it which can either be the nearest city (town, village, etc.) or the road can be tagged explicitly using an is_in tag. Cheers, Mark

If I remember correctly, someone mentioned that roads may have a postcode associated with them. Is that true? Would it use the addr:postcode attribute of the way? Would it make sense to have an addr:city way attribute override an is_in attribute? Sometimes, post offices have different names from the city or town. The post office name would be more useful than the city name. I haven't added is_in or addr:* tags to ways yet; only to POIs. So, my map gets the city information from the nearmost "place" point on the map. Recently, I added addr:* to all shop=bicycle in Finland. I'm also going to add phone and url, but unfortunately, download.geofabrik.de (my source of finland.osm) has been unreachable since Friday. Marko
