[mkgmap-dev] typ question

Sun Nov 7 10:43:38 GMT 2010

Each polygon has a separate generally 4 byte  block referred to at 0x47 of a non NT type file header;
the first two bytes plainly tells me where the polygon block is found,but what do the other 2 bytes refer to?
They are obviously incremental for each polygon and may be related to a polygon’s xpm?

Any ideas?

Thanks

Nick
