Hi Ticker, see https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3948 https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3949 the sortResource.patch reverts these changes. In Mapsource the results are a bit better with your patch. I'll try again with my Oregon later. Gerd

Rounding off population
by osm 30 Jul '23

30 Jul '23

Hi I have a feeling mkgmap rounds off population when a comma has been inserted thinking it is a 'continental decimal comma' In my style I have place=village & population < 30 {set place=hamlet;echotags "village to hamlet"} The following place node gets flagged up as it has been given a population of 1 https://www.openstreetmap.org/node/271408#map=18/50.82664/-1.70104 When I look at the osm tags it contains: population:1,350 Perhaps we should not round off population data? Just a thought. Nick

styles and multipolygons
by helter skelter 21 Jun '23

21 Jun '23

Hello I am rendering lines that are tagged NATURAL=VALLEY to show the name along a trasparent line on the map, using this style code: natural=valley { name '${name}' } [0x12005 resolution 21] It works, but gives a problem with multipolygons that use the same tag: I get the name all along the borders of the polygon, while I would want to see it only inside. Following the style manual (page 11) I am then trying with this code in LINES style file: natural=valley & !(is_in(type,multipolygon,on)) { name '${name}' } [0x12005 resolution 21] and this in POLYGON style file: natural=valley { name '${name}' } [0x10f09 resolution 21] It now works for multipolygons: I see the name only inside, and not along the boundaries. But doesn't work anymore for lines, meaning that I don't get the name anymore. What am I doing wrong ? This is one of the areas with multipolygons tagged as valley, if you want to take a look: https://www.openstreetmap.org/#map=14/46.2816/9.6947 Thank you in advance Diego

Ferry line routing issue
by Vukovics Mihály 18 Jun '23

18 Jun '23

Hello Community, I am struggling with an issue. I am generating Garmin map from OSM o5m sources(geofabrik) using the built-in style. Nor the BaseCamp or my Zümo 396LM is unable to calculate route via ferry lines. The behaviour is very strange, here is an example: Route from Lille to Dover, all avoidances are disabled: unable to calculate route, just a straigth line between the citie. If I am forcing the route inside the service road area of Calais ferry terminal, the route is calculated correctly. Even funnier, that when I shape the route directly to the ferry line, Basecamp swims me on the ferry instead of routing through the port. This behaviour is occuring with other ferry lines (for example Aberdeen - Lerwick). I have checked on openstreetmap and the roads are connected and routable in the style file. Here are the example screenshots about the issue. https://picallow.com/mkgmap-ferry-routing/?usp_success=2&post_id=116783&for… Any ideas or fix? Br, Mihaly

Meaning of some mkgmap output messages
by Carlos Dávila 09 Jun '23

09 Jun '23

Hello all I receive two types of messages when compiling some maps which I don't know how to interpret and if I should take any action to avoid them. First is of the form "(Area): 31177007.o5m: Area.split 1669081 4757504 1670337 4759552 res 11 can't 2 1" which is produced for tile 31177007: 1548288,4409344 to 1673216,4911104 from split file. In some cases the end is "1 2" instead of "2 1". The other one is of the form "Tile selection (0x4a) polygon for tile 25171101 cannot be written in level 0 resolution 20, using 18 instead" and is produced for tile with bounding box 1753088,-8343552 to 3555328,-5726208 from split file.
