The latest impressively detailed manual tells us that: If the type is not extended, it must be >= 0x0100 for a point,
I might be wrong but looking at the img structure I come to a different conclusion: Non extended POIs have their 8th bit set to denote the possible inclusion of a subtype. If so I make the maximum for a non extended POI to be &7F and not &FF as perhaps was implied? '< 0x3f for a line, and < 0x7f for a polygon.' Perhaps explain why non extended lines can't be &40+ ( ie bits used for direction & length of bitstream) Regards nick -- View this message in context: http://gis.19327.n5.nabble.com/type-numbers-again-tp5818050.html Sent from the Mkgmap Development mailing list archive at Nabble.com. _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
