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

Commit r4910: Fix calculation of minimun resolution in overview map: Use same constant as in MapSplitter so that the tile selection polygon 0x4a is not split as this confuses the Garmin PC programs.

Trouble with merging IMG files (for Garmin)
by Tamas Gal 15 Jul '23

15 Jul '23

Hi all, maybe I got that wrong but I thought I can merge multiple IMG files into a single one with Mkgmap. My problem is that I need a bunch of maps and my Garmin 64s only shows 12 in the map selection. A simple solution to this limitation is merging maps ;) Anyways, I gave Mkgmap a try but I get an error which I don't know how to interpret, since it's missing the input files but they are definitely in the folder. Do I maybe need the original OSM files as input files? In that case, the error message is probably wrong. Here is an example where I try to merge the Hungarian and German map into a single IMG: ░ tamasgal@silentbox:~/opt/mkgmap-r4909 ░ 16:29:24 > ls -alh *.img -rw-r--r--@ 1 tamasgal staff 126M Jul 13 16:24 otm-germany-contours.img -rw-r--r--@ 1 tamasgal staff 43M Jul 13 16:28 otm-hungary-contours.img -rw-r--r--@ 1 tamasgal staff 346M Jul 13 16:28 otm-hungary.img -rw-r--r--@ 1 tamasgal staff 246M Jul 13 16:29 otm-slovenia.img ░ tamasgal@silentbox:~/opt/mkgmap-r4909 ░ 16:29:32 > java -jar mkgmap.jar --input-file otm-hungary.img --input-file otm-slovenia.img --gmapsupp Mkgmap version 4909 Time started: Thu Jul 13 16:29:45 CEST 2023 SEVERE (Main): : input file '' doesn't exist WARNING (global): Setting max-jobs to 1 SEVERE (Main): : input file '' doesn't exist Number of MapFailedExceptions: 0 WARNING (global): To reduce the run time, consider increasing the amnount of memory available for use by mkgmap by using the Java -Xmx flag to set the memory to more than 32800 MB, providing this is less than the amount of physical memory installed.
