I've put the full South Australia
Gov Topo map online, this is to zoom 14. Download from here.
Compatible with a sqlite map viewer like Locus. Zoom 14 is probably enough for most driving needs and gets you most street names, but not quite enough detail for bushwalking as it lacks contour lines.
To create your own South Australia
topo maps up to zoom18 using MOBAC (2.1.3 compatible) use this xml
file in your mapsources folder. Note this is the same Location SA Topographic base map as on the SARIG
You will not be able to create a full state map at higher than zoom 14 due to tile count limits, but zoom 15 does contain extra labels, so is worth creating sub maps where higher detail is needed e.g Flinders Ranges. To give you an idea, a map taking in Hawker, Leigh Creek, Arkaroola at zoom 15 is a bigger file than the whole state at zoom 14. Also to note is not all of the state is available at zoom 18, but I'm yet to find things at 18 that I can't see at 17 where it is available.
