Tagging restaurants and categories
by blc 20 Mar '20

20 Mar '20

I've noticed that category searching on my Garmin Nuvi that it will not find Dunkin' Donuts when searching for Donut/Bagel in the USA. I ended up finding out that if an amenity is tagged amenity=fast_food the restaurant will automatically be placed in the fast food category and nothing else. The rub is that pretty much all donut/bagel shops necessarily are "fast food" because the food needs to be prepared well in advance, waiting a half hour or more for yeast to rise for fresh prepartion would be very inconvenient. According to https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/POI_Types it seems that perhaps only one category can be added per restaurant. In this case I wonder if it would be better to have categorization slightly different where fast_food would be a later conditional, so that (in the USA) Fazoli's (fast semicasual italian), Dunkin' Donuts, Einstein Bagels, Winchell's, Lamar's Donuts, Krispy Kreme Donuts, Pizza Hut (fast casual pizza), etc. should show up as their food category rather than simply as fast food. This is a bit tougher to manage with the automatic categorization with the template tags when editing in iD. I found a few independent donut shops and having a hard time deciding whether to mark them as fast_food as they definitely are, but they will subsequently not show up as a donut/bagel shop. Comments, or perhaps nobody really uses these things to find shops anymore...

Performance with --bounds option

Hi Gerd With the current version I have a tile that takes 3.5 hours to build. With an old version (r4295) it took about 3 minutes. Without --bounds it takes 1 minute 15 secs. Relevant options are: --bounds=bounds.zip --location-autofill=is_in,nearest >From the mkgmap.log files: INFO: uk.me.parabola.mkgmap.reader.osm.LocationHook ../mapGB/74220001.osm.pbf: Checking bounds dir took 66 ms ...

problem with reading style file
by Mike Baggaley 19 Mar '20

19 Mar '20

Hi Gerd, it looks like the merge of the is-in branch has introduced a bug in the style file reader. I now get the following error: Error in style: Error: (inc/address:19): Cannot start rule with tag!=* Could not open style style The offending line is: type()=way & highway!=* {delete mkgmap:country; delete mkgmap:region; delete mkgmap:city; delete mkgmap:is_in; set mkgmap:add-to-index='no'} Previous versions are happy with this. Regards, Mike

Re: [mkgmap-dev] precompiled sea
by David 18 Mar '20

18 Mar '20

Hello Ticker and Gerd, I may introduce some noise in your search. I had a problem with sea generation for Ireland and I wrote about that few weeks ago. Gerd or Ticker suggested to me to update my precompiled sea files. I did it but it did not solve the problem of flooded areas (even with OSM latest data). Then I tried options with generate-sea instead of precompiled sea files, without more success. I decided to wait for few days to see if an update would solve my problem. And it worked. All versions (I did not test later than 4466) after the merge of is_in filter, and few ones before produce, a correct result for Ireland. David

precompiled sea
by Mike Baggaley 18 Mar '20

18 Mar '20

Hi, I have not used precomp sea before and am struggling to compile the sea tiles. Using the following process I get a map with no sea: Used osmfilter to extract just the coastline data Used splitter on the coastline data Used mkgmap on the splitter data with a simple style that just processes coastline and with --generate-sea=multipolygon. I can see some img files created in my sea folder Used splitter again on the original data Used mkgmap again with --precomp-sea and --generate-sea=multipolygon Am I doing something wrong? Regards, Mike
