I would like to print a large map of Africa on several A3-pages. I want to hang the map on the wall. So the different pages should overlap a minimum.
The map will be used as a road map, so it should have the highest resolution possible, but consist of 5x7 A3-pages. (A3 is the largest format my printer can handle.) How do I print my map into tiled A3 pages with little overlap?
I am currently using QGIS and OSM-data, but other solutions are more than welcome.
Could anyone point me in the right direction?
