[mkgmap-dev] Size Limits

From Andrew Ayre andy at britishideas.com on Wed Dec 10 17:13:55 GMT 2008

I have an OSM file which is 836Mb in size. When I try to convert it to 
an IMG file I get:

"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."

I understand how to solve this problem (osmosis, osmcut, etc.) but I'm 
wondering what the size limit is and whether it is imposed by the IMG 
file format or mkgmap. Does anyone know?

thanks, Andy
