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!
