Hi all, I've reviewed the problem reported by Stephen: http://gis.19327.n5.nabble.com/ontario-canada-maps-tp5798080.html The error message is: 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. The problem has at least two reasons: 1) A mapper in that area prefers to create extremely detailed ways like this http://www.openstreetmap.org/way/188276794 (the river is ~ 181m long and has 166 points, and many roads in that area are alike) 2) Stephen uses a style that adds more or less each generated POI to the map. With r3128 I've committed a patch that detects duplicate points (in Garmin precision), but that doesn't solve the problem completely, and it only works when --preserve-element-order is active. I don't know why Stephen wants all these POI, so maybe the tags like mkgmap:line2poitype=start, mkgmap:line2poitype=end, and mkgmap:line2poitype=mid are not helping him. I think a better solution would be to change the POIGeneratorHook so that it generates POI with a minimum distance of e.g. 5m, or at least no equal points. I remember that this was discussed before, but couldn't find it in the archives. Gerd
