Hi, mkgmap is dropping international boundaries from a maps (OSM file format but not a download from OMS) without issuing any error message or warning. I checked the image files in mapsource as well as with gpsmapedit, and the national boundaries are not included in the img file. I created a test file to demonstrate the issue with only three line types, national boundaries, provincial boundaries and minor contours, and have uploaded it here. Size = 98.1 MB. http://dl.dropbox.com/u/4900023/cambodia.osm Things I have tried: a) I compiled the original source file in mp format and it works correctly. b) I reduced the OSM file to the smallest size that demonstrated the error by deleting contour lines. If I delete one more contour line from the end of the file the error goes away and international boundaries are displayed. c) I loaded the file in JOSM and checked it. The international boundaries displayed correctly. I saved the file to a new file name, and although the elements were rearranged and the file size increased, the international boundaries were still dropped when I compiled the file. d) I compiled with no options set, and checked the img with gpsmapedit, and it WORKED correctly. The boundaries displayed in the img file. e) After further experimentation I found that removing --remove-short-arcs=5 from the command line cause the international boundaries to display correctly. Command line java -ea -Xmx2000m -jar ./mkgmap-1581/mkgmap.jar --remove-short-arcs=5 cambodia.osm Does not work. Thanks for any help Garvan
