[mkgmap-dev] Norway not buildable with the no-trim option

Sat Dec 22 10:11:02 GMT 2012

I'm not able to build the map for Norway with the "no-trim" option.

- Source:norway extract from geofabrik from 22.12.2012
- Bounds from 18.11.2012, Sea Tiles from 12.12.2012
- mkgmap 2412 / splitter 263

Splitter options:

This seems to be the problem area (which spans over a large area):
Area 65780001 covers (57.568359375,11.689453125) to
(61.5234375,31.552734375) and contains 674846 nodes (84 %)
Area 65780001 covers (0x28f000,0x85000) to (0x2bc000,0x167000) RU-Saint
Petersburg

I let splitter calculate the tiles:

# List of areas

#       : 68.774414,16.435547 to 69.169922,18.544922

mkgmap refuses to build the tile 65780001:

java -Xmx6000M -jar

There is not enough room in a single garmin map for all the input data
   The .osm file should be split into smaller pieces first.

Perhaps a problem within the map data ... how to investigate it ?

Screenshots with the trim option:

PS: With the trim option the map is successfully buildable.
