Commit: r988: Generate sorted road data to enable finding addresses and intersections.
Version 988 was commited by markb on 2009-03-30 21:50:43 +0100 (Mon, 30 Mar 2009) Generate sorted road data to enable finding addresses and intersections. Incremental search for alphanumeric street names basically works but could do with more testing with non-ascii characters. Incremental search for numeric street names and all city names does not work although if you input the whole name it will match. No support yet for house numbers.

I've tried to test with non-ascii characters, but it appeared that it doesn't work for me at all. Tried run with --location-autofill=3: Locator City Map contains 0 entries Locator Places Map contains 9216 entries Locator City Map contains 0 entries after resolver run 1 Still unresolved 9216 Locator City Map contains 0 entries after resolver run 2 Still unresolved 9216 After uploading the map to a Garmin 60Csx, "Addresses" option does not appear in the "Find" menu. So, the map behaves the same way as any other map without MDR file. AFAIU, the is_in tag is used for search index. My OSM dump (part of Russia) has several regions, where is_in tag is put on many streets. -- Totus tuus, Glebius. GLEB-RIPE

You are supposed to be able to draw a polygon, marked with "place=village/town/suburb(etc)" and "place_name=whatever" and then all streets inside the polygon would behave as if they included an "is_in=whatever" tag on the way. POIs would behave similarly. See http://wiki.openstreetmap.org/wiki/FAQ#What_makes_a_road_belong_to_a_city.3F The "is_in" tag is supposed to be used only in exceptional cases. I've been doing this around my area (South Wales) and where possible, flagging the polygon with "landuse=residential(etc)" which shades the map nicely: See http://www.openstreetmap.org/?lat=51.53023&lon=-3.67813&zoom=15&layers=0B00F... I sure hope mkgmap makes use of these polygons or I'm wasting my time!! Steve

is_in is a workaround for missing admin boundary polygon. I tried correcting the vast amount of is_in's on german place nodes to at least be able to make a place hierarchy possible.

My guess is that it does not - A residential area is not the area which contains all roads belonging to that place. I live in the countryside and i am far far away from the next residential area or better place node (at least 5-6 km) so there is no way to know the correct place name than guessing by distance to the next place node. There is no good solution to this problem except putting administrative boundaries around the place but at least in germany we are far away from having admin boundaries for all hamlets, suburbs, or even small villages. Another thing still unsolved is that the next place node for me is place=village name=Bokel So my street ends up in Bokel - The problem is that the postal address is 33397 Rietberg where Bokel is one village of. So there is no way of finding the correct adress.
