I think now that either way could be implemented, with special software for the
vector map. A bit map you can upload, and just view, but a vector map, you can
save space, but when uploaded, you could easily have software to map out the area.
The whole reason for this project/thread for me was to be able to scan a room
using ultrasonic rangefinding, then upload the map and save it. This would give me
an 'aerial' view of the area. This could be loaded into that mission editor from
that university(can't remember the names), and then a map could be made. This has
very few applications, but I thought it would be interesting to do.
