Recent TM versions allow non-rectangular Jobs. Within the job a 
descriptive description is usually sufficient. It's not like the city in 
the center could be missed, no?

That is right. Sometimes I let the machine choose, to avoid making a 
decision and sometimes I want to pick a specific, interesting location.

Re: features crossing the task boundary: I usually complete them in the 
context of my current task, if they do not reach too far into the next task.

I often wondered about that too. Most of the recent building trace jobs 
drive me out of my mind because I can't wrap my head around tagging 
clumps of pixels as huts. Then again, I'd probably also be of no use if 
I just map the roads and keep all the fun for myself, leaving others to 
struggle with the buildings.

I guess that's a loose-loose situation right there.


On a similar tangent, it would be really great to have a global TM with 
finishing levels which keeps track of up-to-date-ness, complete-ness and 
data fidelity.

Pierre, you're already working on that? Great! would it be possible for 
mappers to dynamically split tasks? or will the admin have to do that? 
Anyways, looking forward to that!
