[OSM-newbies] Preparing a mapping party: cutting the cake

[ivom]

Hi,

I took part in two mapping parties previously and have noticed the 
returning ad-hoc process of carving a paper map into pieces with 
pen&pencil and distribute the sub-areas to be mapped among the various 
participants this way.

I wonder if there is some sort of app/procedure available that could 
assist with this planning proces and as a result would extract osm data 
per area.

Do you have experience preparing mapping parties? Please post your 
tips&tricks.

Bye,
Ivom
