[mkgmap-dev] Duplicate IDs

Mon Jan 7 19:52:47 GMT 2013

Thanks, Gerd.

There seems to be a lack of compatibility between SRTM2OSM files and 
other programs. Having converted them to pbf with OSMConvert, the files 
would not compile - no errors - just produced essentially empty IMG 
files. After a lot of experimentation, it turned out that the problem 
was the 19 digit (64 bit) IDs in the files. But since they all start 
with the same sequence, I was able to cut this back to 8 digits with 
Notepad++ (not a quick process). They then compiled. There must be an 
easier way!

I know mkgmap can cope with 11 digit IDs, but it seems it can't handle 
19. What is the limit? (During the process I also discovered that 
Osmosis seems to take 8 but not 10  -  I haven't tried 9).

Thanks again for the advice.

Roger
