I’m probably being rather slow here. I’ve generated a number of maps in GroundTruth, but the registry entries seem to overwrite each other. I’ve tried installing with MapSetToolkit, but have forgotten the particular sequence I’ve used to get good registry entries in the past. So when I’ve got two registry entries, MapSource crashes.
Basically, I’m trying to generate transparent overlays (some with non-OSM compatible data - derived boundary data) which can be downloaded onto the Garmin. My problem is that GroundTruth always seems to generate the .TYP, .TDB etc and the registry with product code = 1.
There’s command-line options you can use to change the productcode or family code
--fc, --familycode=code
Garmin map family code (integer, default value is 1)
--fn, --familyname=name
Garmin map family name
--pc, --productcode=code
Garmin map product code (integer)
--pn, --productname=name
Garmin map product name
I have broadly sorted out this problem following up the hints given: I now use all the above options, and keep my maps in separate directories. I think before the problem was that I was not changing product code and the registry install was overwriting the previously installed map.
I now have overlays of : no-name streets (very useful as I can’t use the big Cloudmade IMG); OSGB (for biological recording); County boundary (for biological recording); cake-slice boundaries; and (a bit sad this one) 1,2,3 km circles from the house to enable me to see which unmapped areas are closest. I also have transparent SRTM contours via the Scottish Mountaineering Club page.
