Thread: Selectable maps with same FID possible?

gmaptool shows one maps has FID 4600 and the other FID 4620. I tried changing the FID to greatly different values. For further information I added the gmaptool info for each file.

I changed the map-id and this worked for one map type; Thanks

Two other map groups still have a problem. I think they have different PID, different names ands Map-id., but I do not know what I am looking at. Here is the gmaptool "info" for both map samples. Any further guidance would be appreciated.

End.

The FID of all these mapsets is 0.

Contour Aus 2.00 has PID 7200, FID 0
Contours Australia 5m has PID 8500, FID 0

Shonky Topo has PID 800, FID 0
Shonky Topo w/out Contours has PID 801, FID 0

The value 1252 is listed under "CP", what ever that is. I do not know what all the values listed by GMapTool are!

Chris

1252 is Code Page, West European.

Thanks. I guess the code page can/should be 1252 for all the maps. I still do not know what factors group these maps together in the Nuvi!

Chris

FID 0 is a kind of depreciated value, this value is used by maps, that do not belong to "Family" but "Products". Both names comes from Mapsurce registry keys on PC. I'm not sure, how current gps treat "Products", maybe just as you observe.

For this maps you can change FID/PID value with gmaptool, but in a bit complicated way. You need to split img into maps (not "files for Mapsource", but "single maps") and than join all this maps giving mapset name and new FID/PID numbers in gmaptool join options.

For 3 different mapsets, I finally managed to alter them so that, the maps in each mapset could be selected individually, both visible, neither visible or both visible.

Firstly I had 2 maps generated by gpx2img [Only registered and activated users can see links. ]. These are transparent maps. For these I used GMapTool [Only registered and activated users can see links. ] and changed the map name and map ID.

I had both 10m and 5m transparent contour maps from Contours Australia. [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ] . These maps had the same PID and a FID of 0. For these I had to use GMapTool to split one of the img into maps (not "files for Mapsource", but "single maps") and then join all these maps giving a mapset name and new FID/PID numbers in gmaptool join options.

Similarly I used the same approach to alter one of the maps I was using from the Shonky Topo maps [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ]

In the end I managed to make the various maps individually selectable, but I could not have done it without help from people on the forum [Only registered and activated users can see links. ]

Thanks to all
