<DIV><FONT size=2 face=Arial>Each Typfile is designed for only
one FID, not for a (map-)name. The FID is stored inside at Byte 48 and 49.
It is irregular, if 2 different typfiles with the same FID exists. If you use
Mapsource or MapInstall to send the map's to GPS, this can never occur, because
Mapsource shows only 1 map per FID. The PID is not interesting. </FONT></DIV>

<DIV><B>Betreff:</B> [mkgmap-dev] Line TYP Collision between two different
maps</DIV></DIV></DIV>
<DIV><BR></DIV>Hello,<BR><BR>I am seeing a collision between custom line TYPs
when I generate two different .img files (different Map IDs (--mapname=
parameter to mkgmap)). Here is what I am seeing and was wondering if
anyone could offer ideas:<BR><BR>Map 1 : TYP file : Type=0x100001 (solid red),
contains a single line<BR>Map 2 : TYP file : Type=0x100001 (solid green),
contains a single line<BR><BR>Both .img files get loaded into my gps (montana)
and are enabled and both lines show, however, map 2's lines shows as red, not
green, as expected. If I disable map 1, map 2's line still shows
<B>incorrectly</B>. If I delete map 1 form the gps, then map 2's line
shows correctly. I thought that each map had its own TYPs and the GPS
would sort out which TYP to display for each map's line. It seems that the
gps unit is getting confused or caching the line TYPs from the "first loaded"
map and using those for subsequent maps. If it were true that an earlier
loaded map's custom TYPs override later loaded maps, how would it be possible to
sort out custom types across different maps?<BR><BR>Another thought I had is
that since both my maps share the same family id and product id, could this be
causing the collision? I cannot find any decent documentation on what
family id and product ID are supposed to be.<BR><BR>Thanks for your
help,<BR><BR>Scott<BR><BR><BR>
