Thats right - we take GPS units to map stuff with, and I will have a
load of GPS units to lend out to anyone who wants to use them.

Recently Yahoo have allowed us to  work from their aerial imagery,
which means a lot of the tracing can be done from the comfort of a
chair.  But, we still need to get the names of the streets - which
means walking down them.  At a mapping party in London recently, we
had a lot of success with printing out aerial imagery and noting down
road names on the maps, and then uploading the data.

Another problem with satellite imagery is that it isn't always current
- so new developments won't appear, requiring a good old GPS.

Finally, satellite imagery provided by Yahoo is typically only
available for urban areas.  So mapping downtown Victoria will be no
problem, but if people want to go out further and map some rural
areas, a GPS unit could also be required.

So - I'll have some GPS units which will be useful for some stuff.
Having a laptop will also be helpful, as will print outs of yahoo
images and OSM maps.

Best,
